CHALLENGING THE GENIUS MATHEMATICAL CURRICULUM AFRICAN MATHEMATICAL GENIUS BENNE SO
MISSION The mission of the curriculum is to center, educate and nurture all students to achieve their maximum potential while developing future
world leaders. PHILOSOPHY
The philosophy is that all children can and will learn to their maximum potential and that their dreams should be their only boundaries.
IDEALS The ideal is to provide a holistic program that will produce students who are :
Academically competent
Behaviorally confident
Socially conscious
Culturally aware
ACADEMIC FOCUS The academic focus is an experiential mathematics curriculum with strong emphasis in individualization and critical thinking. “Learning
by doing” is the primary teaching strategy because people remember ninety percent of what they see and do and only ten percent of what
they read. DISCIPLINE
The discipline approach is taught using ethical principles of truth, justice, righteousness, order, balance, harmony and reciprocity. There are
only three rules: Respect self, Respect others and Respect the environment.
GENIUS
Dr. Abdulalim A. Shabazz of Clark Atlanta University earned his Bachelor’s degree from Lincoln University, Master’s from Massachusetts
Institute of Technology (MIT) and Doctorate from Cornell University. He has directly and indirectly produced more than half of the current
Black mathematicians (at the Ph.D. level) in the United States. He is African Mathematical Genius at its finest.
Thanks
Special thanks and recognition is extended to the Marcus Garvey Academy and their director, Anyim Palmer for providing the role model
that inspired us to undertake this process. Thanks to the Roots Academy for providing an African centered curriculum prototype. Sankofa
Publishing Company wishes to thank Dr. Shabazz for agreeing to edit African Mathematical Genius with our staff. We are truly honored
to have his contributions and his validation of our work.

Message from Dr. Shabazz
Studies paint a dismal picture of underachievement and underrepresentation of Africans, Native
Americans and Hispanics in the mathematical sciences, engineering and technology. In terms of
historical time this is a recent phenomenon. From the beginning of humans until the fall of
Granada in Spain in 1492, Africans, Native Americans, Hispanics and their ancestors were the
leaders of all intellectual pursuits including the arts, sciences and mathematics.
We seek to maximize each student’s motivation and raise self-esteem while producing excellence in
mathematics. Experience teaches the best ways to change these misconceptions are: (a) to show
students how they, through their ancestors, have contributed to the growth and development of the
mathematical sciences through the ages; (b) to provide them with role models in their own images
and with many examples of successful students just like themselves; and (c) to create a favorable
humanistic learning and teaching environment in which they can mature and develop to a high degree
rapidly.
The basic assumptions are:
all students can excel in mathematics
a high level of success depends upon the students’ perception of their ability and upon their
hard work
students come to school to learn.
Such assumptions and an understanding thereof are necessary if all students are to have hope of
achieving educational success.
To effectively teach all students, teachers must take them as they come to the classroom. As Dr.
Clarence H. Stephen, professor emeritus of mathematics of the Potsdam College of the State
University of New York, so eloquently says, “We teach the students we have, not the students we
wish we had”. Lack of knowledge or background should not be used against students. Not having a
rounded mathematical background is not a real barrier to mathematical development. What is
missing should be supplied; what is broken should be fixed, and should be done as quickly as
possible. Certainly, students in the beginning should be given problems and challenges which they
can handle, but given in a humane way, never seeking to injure or lower self-esteem. Indeed, this
is in accordance with proceeding from the known to the unknown.
7
With this background teachers must have the:
knowledge of the subject to be taught
will to teach all students
belief that all students can learn
historical facts so that all students can learn the part they have played in the creation and
development of mathematical knowledge
willingness to accept students as they are and take them where they should go
motivation to inspire students to work harder
desire to publicize their students’ success in mathematics.
Other areas to consider are:
ATTITUDE
1. Consistently show students the role they have played in the development of mathematics
through historical and current facts
2. Have students write reports on multi-cultural mathematicians--ancient and modern
3. Allow students frequent experiences of success by having them to solve exercises of low
difficulty then solving those of higher complexity
4. Allow students to experiment with concepts and develop rules and methods on their own,
while the teacher facilitates the process
5. Allow students to compare and debate their concepts and methods with others
6. Allow students to prove or disprove mathematical assumptions, written and oral
7. Allow students to teach the class about a topic that they enjoy
CONCEPTUALIZATION
There are three common ways to perceive a mathematical concept or idea:
1. Physical model (geometric representation, 1-3 dimensions)
2. Algebraic model (formulas, equations, inequalities, “analytical form”)
3. Mental model (written or verbal representation that best describes concept or idea)
COMMUNICATION
Since spoken/written language is first used by the student to convey his/her thoughts and
concepts, it is natural to engage the student in using the language with which he/she is already
familiar to express and define “mathematical” language.
1. Have students translate written/spoken language into mathematical symbols and expressions
2. Have students check the reasonableness of statements and results
3. Have students check the validity of statements
PROCESS
Natural learning takes place first by physical activity or processes that convey an idea or
concept. Next is learning by verbal communication, which conveys an idea or concept through the
spoken word. Last is learning by written or symbolic communication, which conveys an idea or
concept through symbols such as alphabets and/or numbers, etc.
8
1. Conception-Object, Idea, Concept
2. General familiarization-Superficial introduction of object, concept or idea
3. Experimentation-Contact and close observation of object’s, concept’s and idea’s properties
and qualities
4. Assumptions/Theorems/Rules-Develop rules and definitions based on experimentation
5. Application-Perform tasks based on rules and theorems
INTRINSIC MERIT
Experimentation with mathematical concepts and properties is the scientific activity that
naturally stimulates the student to think clearly, logically, and constructively. Comfort in
experimentation gives the student intellectual freedom causing that student to reach within to
create unique concepts.
Logical training causes the student to constructively access, arrange and use facts to
successfully produce a desired outcome. Early exposure of the student to mathematical concepts
and methods naturally causes the student to be more “friendly” with mathematics in later years.
RELEVANCE
The learning and practice of mathematics by the student will train that student to logically
create strategies and solutions relevant to the needs of home or community life. Further the
practice of mathematics will train the student in efficient production of self-determined
objectives and goals.
In-depth mathematics training at the early years increases the likelihood of mathematics and
scientific success in the middle and high school ages. The Challenging the Genius Mathematics Cur-
riculum prepares children for their future leadership.

I ntroduction
The Challenging the Genius Mathematical Curriculum is organized into four books. The
first book is Potential Genius our preschool curriculum. The next books are African Math-
ematical Genius Giri So, Benne So and Bolo So. The African Mathematical Genius books are divided
into three themes in each book for a total of nine themes. The themes are infused across the
curriculum with goals and objectives for math, language arts, science, social studies/history/
geography and health with sample lessons in art, PE and music. The math theme is fully developed
with class introductions of topic, vocabulary, exercise and activities.
The basic strategies and techniques utilized in a holistic program include repetition and drill
while recognizing the concept of patterning. The drills used encompass a multi-sensory approach
for culturally relevant learning. This enables students to transfer these experiences for
implementation.
HOW TO USE THIS BOOK
This book should be regarded as a guide for educational creativity. It is not a recipe. Each
theme is accompanied by an introduction explaining the African history of mathematics. These
introductions are followed by goals and objectives with page numbers referring to suggested
activities. The language of mathematics is included, as is a collection of worksheets for
practice and reinforcement. Mental math and review exercises are included in each theme to check
mastery. Games and activities are included, and can be used during instruction or for additional
enhancement. Each theme ends with goals that offer suggestions to extend the lessons across the
curriculum.
This book can facilitate instruction. It is filled with suggestions that we have found sound and
useful. Be creative! Develop your African Mathematical Genius.

K emet is where we find the earliest documentation of measur-
ing time. Tony Browder, in Nile Valley Contributions to
Civilization, shows a shadow clock which is more than 3,400
years old. It casts shadows on a bar marking off the hours as a
crossbar turns toward the east. There were many timekeeping devices
in Kemet, including stone sundials and the tekhnu (obelisk) which
was used to measure the equinox. Today, the clock is used to measure
time by the second, minute and hour. The first clock made in the
United States was created by Benjamin Banneker, who also wrote an
almanac and designed the street plan of Washington, DC. The
ancestors of KEMET and Banneker operated on Imani (faith) as they
considered tasks that were beyond their time.
Success as a form of justice was their reward.

Historical Look
Mexico City, Mexico, North America The Aztecs, an indigenous people of Tenochtitlan or present day Mexico City, began making their calendar in
1427 and completed it in 1479. They used pictographs to represent the information. The circle has twenty
squares representing each day of the Aztec month. They are called the Ring of Solar Archetypes. The Aztec
year consisted of eighteen months. This amounted to three hundred sixty days. Additionally five days were
added called Nemontemi (unlucky days) which were sacrificial days. The stone was used not only as a calen-
dar but also as a sundial.
Egypt The worlds first calendar was the ancient Egyptian calendar. It dates back as far as 4236 B.C.E. This calendar was based on the moon’s
cycles and was regulated by the stars. The lunar month was determined by the interval between successive full moons, which is precisely 29
days, 12 hours, 44 minutes, and 2.7 seconds. The word month is derived from the mona, which means “moon”. Additionally, the astrono-
mers of KMT or Egypt developed stellar and solar calendars. The solar calendar provided a more accurate measurement.
Asia The Islamic calendar begins with Muhammad’s flight from Mecca to Medina in 622 A.C.E. This is also a lunar calendar.
The Chinese calendar is rooted in their philosophy and astrology. It is greatly influenced by Lao Tzu and Confucius, the founders of Taoism
and Confucianism, respectively. There are twelve signs in Chinese astrology that corresponds to one year. In this zodiac calendar there are
twelve animals that represent each year. Each person is born in one of the twelve zodiac animals. The animals are as follows: The Boar, the
Rat, the Ox, the Tiger, the Rabbit, the Dragon, the Snake, the Horse, the Ram, the Monkey, the Rooster, and the Dog. The Chinese New Year,
called Nian, is also different from the Western new year because it is lunar instead of solar.
Europe In parts of Scandinavia above the Arctic Circle the sun does not set for parts of the summer and during parts of the
winter the sun does not rise. Because of this the Scandinavians divided each sun-cycle into eight sections. A place
on the horizon that lay in the center of these eight marks is called a “daymark”. Time is identified by noting when
the Sun stood over one of these daymark-points on the horizon.

Reading The Clock
THE FACE OF A CLOCK
Clocks have three hands (when equipped with a second hand) that are used to tell time. The
short hand on the clock points to the hour. The long hand points to the minute.
All of the parts together make up the face.
There are 24 hours in 1 day.
Each hour has 60 minutes which equals one revolution of the minute hand.
Each minute has 60 seconds, one revolution of the second hand (each mark on the clock rep-
resents either one second or one minute).

Reading The Clock
THE FACE OF A CLOCK
The short hand tells you the hour. On the clock above the time is 3:00. This is because the short hand is on the three
and the long hand is on the twelve.
The long hand tells you the minute counting by ones. For every numeral displayed on the clock from 1 - 12 you count
by fives.
If the short hand is between two numbers, pick the lesser of the two numbers for the hour.
The time here is 5:09.

More with Time
When working with standard time (dividing the day into two twelve hour blocks), the same hour can be used to mean in
the morning or evening. You use the abbreviation ‘a.m.’ to tell morning time and the abbreviation ‘p.m.’ to tell evening
time. The abbreviations are Latin and mean ante meridiem(before noon) and post meridiem(after noon). For instance
9:00 a.m. means 9 in the morning, while 9:00 p.m. means 9 in the evening.
Scientists use a 24-hour clock to avoid such confusion. Beginning at midnight (the beginning of a new day), the
hours are numbered from 0 to 24. We call this method of telling time military time. When using military time, you
say the time in a different way. For instance, 9:00a.m. is not “nine o’ clock in the morning,” but “nine hundred hours.”

segments intersect, they meet
and cross at a point.
When two lines or line
segments never cross
(intersect), they are parallel
lines.

When two lines or line
segments cross (intersect) or
join to form a 90° angle, they
are perpendicular. The sign
used to show that lines are
perpendicular is .

Angles On The Clock
The two hands of a clock form different angles at different times.
At 9:00 a Right angle (90°) is formed.
Clock Dance - This is a multi-sensory activity and game that teaches students how to tell time. It is recommended that
the teacher demonstrate this activity, practice with the students and then call on students to demonstrate their
proficiency.
Stand with one arm and hand pointing straight up and the other arm in front of the body, bent at the elbow with hand
and fingers pointing up tell the students that this is 12:00. Rotate either or both arms to your left (which appears to be
clockwise to students) and tell them the time you are signifying. Students should move their arms to the right to see
that they are matching a clock. This activity will teach students to tell time by hours and by minutes. As they slowly
rotate their straight arm (the minute hand of their clock) with jerking stops, they can count by fives to 60 and complete
a circle. This activity takes a little practice, but once the children catch on they can be asked to show the time and tell the
time. Other suggestions for this activity include: open eyes, closed eyes being a.m. and p.m. respectively; identifying
acute, obtuse and right angles.

Three Dimensional Objects - Space Figures
Polygons and circles are flat, or two-dimensional objects. They have length and width but no height or
depth. Figures that have height or depth in addition to length and width are three-dimensional or space
figures. Among these are cubes, prisms, pyramids and spheres.
Cubes, prisms, pyramids and other similar solids have sides that we call faces. Faces are flat surfaces
that are in the shapes of polygons. Faces meet at edges. The edges are line segments. The line segments
meet in vertexes.

Prisms have two parallel, congruent
polygon-shaped bases. The sides of
prisms are all parallelograms. Each
face that is not a base is called a lateral
face.

A Pyramid’s base can have the shape of
any polygon like the prism. All other
faces of a pyramid are triangular.

Cylinders are solids with two circular
bases.
Spheres have no flat faces and no
vertices. A sphere has the outline of a
circle when viewed at an angle.

Daily Drill
Telling Time Have students record the time each day they come to class. Let one student come to the front and
give the correct time.
Use a manipulative to tell the time by each hour, each half hour, each quarter hour, by ten minute
and five minute intervals.
Geometry Match Draw all the shapes, angles, etc. on a set of index cards. Draw the words that correspond to these geometric shapes on a
different set of cards. Scramble the two sets of cards together. Have students match the geometric shapes to the correct
word.
“Geo Fish!” Create geometric flash cards with at least four duplicates of each type of card. Make different sets of cards, I.e., angles,
types of lines, etc. Shuffle the cards and deal to student groups, (between 2-4 students in a group). This is similar to
playing go fish. Students then have to make matches with the cards in their hand by requesting that card from anoth-
er player. If the other player doesn’t have the requested card, the tell the player go “Geo Fish!”.

T he people of Kemet were not static - they were didactic. This means
they were constantly changing and growing in response to their
environment. They even developed a system of multiplication by
doubling.
Change is critical for growth and development. Everything created by
humans is engineered and to engineer, knowledge of advanced mathematics
is necessary. Multiplication and division, like addition and subtraction,
are reciprocal processes that create number patterns. To achieve the greatness
of our ancestors, Nia (purpose) must be maintained to acquire the skills
necessary to succeed. Using these math skills enables creativity in the new
age of technology.

Historical Look
India The Harappan people of India, 2500 BCE, was followed by the Vedic civilization. The Vedic civilization, parent of modern
India, used the gunja seed, similar to the grain in English measure, as the unit of weight for precious metals.
Scotland John Napier of Scotland, circa 1600, solved multiplication problems using sets of rods. To multiply 13 by 2 do the fol-
lowing:
Draw a square and divide it in half vertically. Write 1 and 3 across the top of each new rectangle and the 2 to the right
of the second rectangle:
1 3 1 3 1 3 1 3
0 0 0 0
2 2 2 2
2 6 2 6
2 6
Divide each rectangle in half diagonally. Multiply the 3 by the 3. Write the ones in the bottom triangle and the tens in
the top triangle. Repeat for 1 and 2.
To find the product add the numbers along the diagonals. The product of 13 and 2 is 26.
65
Multiplication and Division
Multiplication and division, like addition and subtraction, are inverse operations of each other.
Multiplication is a faster form of addition. To multiply is to add a series of one number to itself a specific number of
times. This is determined by the multiplier. A few of the signs for multiplication are: x and •.
4 x 3 = 12 (4 + 4 + 4 = 12)
and
3 • 4 = 12 (3 + 3 + 3 + 3 = 12)
In the equation 4 x 3 = 12,
4 is the multiplier
3 is the multiplicand
12 is the product
Division is the process of finding out how many times one number will fit into another. The signs for division are:
÷, and — (the fraction bar).
12 ÷ 4 = 3 (4 goes into 12 three times because 3 x 4 = 12)
12 ÷ 3 = 4 (3 goes into 12 four times because 4 x 3 = 12)
In the equation 12 ÷ 4 = 3,
12 is the dividend
4 is the divisor
3 is the quotient
66
Multiplication and Division
Multiplication and division are used to solve many problems in life. Among these are your weight, the amount of
money you earn, how many days you attend school in one year, how many treats your teacher has to buy for class, etc.
Ex. Ms. Brooks has 5 students in her class and she wants to give each one of them 2 treats. How many treats does she
need to buy?
There are several ways to solve this problem:
1. Hold up two fingers and count by 5’s
2. Hold up five fingers and count by 2’s
3. Add 5 + 5
4. Add 2 + 2 + 2 + 2 + 2
By using either of these techniques you will find that Ms. Anderson has to buy 10 treats for her class.
To check by the inverse operation: 10 treats ÷ 5 students = 2 treats each
Ex. Mr. Anderson is making a photo album of his class. He has collected 12 pictures and has 6 pages in his album.
How many pictures can he put on each page?
There are several ways to solve this problem as well:
1. Draw 12 lines, count 6 and put a ring around them, count 6 again and put a ring around them. Count
how many rings you have when you have all the lines ringed.
2. Ask yourself, “6 times what number equals 12?”
3. Count on your fingers by 6’s until you get to 12, the number of fingers you’re holding up when you get
to 12 is the answer.
By using either one of these techniques you will find that Mrs. Thompson can fit 2 pictures on each page.
To check by the inverse operation: 2 pictures x 6 pages = 12 pictures total

15 ÷ 3 =
2. If you had 3 uncles and they each gave you 2 dollars, how much money would you have?
(hold up 3 fingers and count by 2’s)
Using the graph to the right:
3. If each guitar represents 3, how many guitars are there?
3 x 3 =
4. If each radio represents 2, how many radios are there?
5. If each piano represents 10, how many pianos are there?
6. If there are 10 rows in the auditorium and 6 people can sit in each row, how many people can be seated in the
auditorium? 10 x 6 =
7. If there are 5 rows in your classroom and 5 people can sit in each row, how many people can sit in your classroom?
8. If 20 people were able to sit in a classroom that had 4 rows, how many people sat in each row?
20 ÷ 4 = ( 4 times what number equals 20)
9. If 30 people were able to sit in an auditorium that had 10 rows, how many people sat in each row?

Exponents
On the previous multiplication and division fact sheets, there were problems such as 2 x 2 = 4 (also read as 2²).
When a number has a smaller number at the top to its right it is being powered to an exponent (ex. 2³). Exponents show
how many times a number, the base, is used as a factor. The answer is a power of the factor raised to the exponent.
5 x 5 = 5² =25
It is read as “5 to the second power” or “5 squared.”
2 x 2 = 2² =4
It is read as “2 to the second power” or “2 squared.”
10 x 10 = 10² =100
It is read as “10 to the second power” or “10 squared.”
3 x 3 x 3= 33 =27
It is read as “3 to the third power” or “3 cubed.”
Can you show what five to the fourth power would look like?
2 to the third power?
4 squared?
79
More on Exponents
Exponents show how many times a number is used as a factor. The answer that you get is said to be a
power of the factor raised to the exponent.
5 x 5 x 5 = 5³ (3 factors of 5)
base exponent
The above problem is read as “five to the third power.”
To find the answer:
5³=
5 x 5 x 5=
5 x 5 = 25 (compute the first two)
25 x 5 = 125 (compute the last one)
So, five to the third power is equal to 125.
Can you compute two to the third power?
23=

Exponents, Roots, and Logarithms
The inverse operation of exponents is roots or radicals and logarithms. The root is the base in an exponential expression.
The logarithm (or simply log) is the exponent. For instance,
Exponent Root Logarithm
23 = 8 The cubed root of 8 is 2 Log base 2 of 8 is 3
52 = 25 The square root of 25 is 5 Log base 5 of 25 is 2
Use the color codes above to complete the following:
42 = 16 The _____________ root of 16 is ___ Log base ___ of 16 is 2
24 = ___ The______________ root of ___ is ___ Log base ____ of ____ is ___
33 = ___

Engineers & Multiplication
Engineers use multiplication to help them perform several tasks. One in particular is calculating the area of different
surfaces and figures. For example, to calculate the amount of steel needed to build this Warren Truss (a truss is a major
type of engineering structure)*:
First find the perimeter of one triangle:
Remember the perimeter is the distance around a figure. The perimeter of one triangle is 9 because each side is equal to 3.
Then find out how many triangles there are in all:
If you count correctly, you will see that there are 21 triangles.
Then use multiplication to find the total perimeter of the truss:
21 x 9 = 189
*each member is doubled.

A Briefing on Measuring Length and Distance
The U.S. Customary System or the English System is our standard for measuring length. The Metric system is used
in Europe and other parts of the world.
The U.S. Customary System: The Metric System:
Measure Abbreviation Equivalent
inch in. 12 inches
equals 1 foot
foot ft. 1 foot equals 12
inches
yard yd. 3 feet equals 1
yard or 36
inches equals 1
yard
Measure Abbreviation Equivalent
meter m 1 meter equals
100 centimeters
centimeter cm 100 centimeters
equals 1 meter
kilometer km 1000 meters
equals 1
kilometer

Computing Area
5in
The area of a square is
S² or (side X side).
The area of this square is
25in2 because 5x5=25
Another way to find the
perimeter of a square is to
multiply the length of 1 side
times 4.
The perimeter of this square is
4x5=20in
10cm
4cm
The area of a rectangle is
length x width.
Length = how long
Width = how wide
The area of this rectangle is 40cm2
because 10x4=40.
Another way to find the perimeter of a
rectangle is to multiply the length by 2
and then the width by 2 and add.
The perimeter of this rectangle is 28cm
because:
2x10=20
2x4=8
20+8=28
4m
3m
The area of a triangle is (base
x height)÷2.
Base = the bottom of a
triangle
Height = how tall
The area of this triangle is
6m2 because 4x3=12, and
12÷2=6.

s tudying the heavens and the universe must have been a favorite pasttime of the
ancient people of Kemet. Around 5,000 B.C.E., the people of Kemet were using an
astronomical calendar. They developed solar, stellar and lunar calendars. They
recognized that the solar year was defined by a period of 365 days, 5 hours, 48
minutes and 46 seconds—the time it takes the Earth to make one complete revolution around
the sun. Their calendar had 12 months of 30 days each adding 5 days at the end of the year
to celebrate birthdays of the Gods. Each 30 day month was divided into 3 weeks of 10 days
with 24 hours in each. The year was divided into 3 seasons to correspond with the Nile and its
effect on the people. Instead of a leap year every 4 years to account for the quarter day each
year, the Kemites added a new year every 1,460 years.
The people of Kemet associated the stars with Gods to create a circle of 360 degrees, and
the 12 signs of the zodiac. The tradition of the fascination with the heavens continues with
the Dogon people of Mali, West Africa who explained Sirius and Sirius B to contemporary
scientists.
Life for Kemites was mathematics. Kemites were self-determined to create an
understanding of order in the universe. Practicing self-determination opens the mind for
creativity.

Historical Look
Alaska, North America
Although the first Iditarod , “The Last Great Race”, was held in 1973, it’s histo-
ry dates back to 1925, when Nome was hit by an epidemic of diphtheria. A se-
rum was transported from Anchorage to Nenana, Alaska by train. Mushers
(dogsled drivers) then relayed the serum to the residents of the town. Near some
of the checkpoints of the race such as near the Bering Sea, wind chill tempera-
tures can fall as low as –73 degrees Celsius( - 100 degrees Fahrenheit).
Al Grillo/Associated Press
Germany/Poland
Daniel Gabriel Fahrenheit, a German physicist, invented the alcohol thermometer in 1709. In
1714, he invented the mercury thermometer that is still in use today. He also invented the
Fahrenheit scale that is commonly used in the United States.
Sweden
Anders Celsius was an astronomer that invented the Celsius thermometer, also known as the
centigrade scale.
He was a professor of astronomy at the University of Uppsala and also studied the Aurora
Borealis, or Northern Lights.

The Calendar
There are 24 hours in 1 day
7 days in 1 week
12 months in 1 year
52 weeks in 1 year
365 days in 1 year
366 days in 1 leap year
(A leap year occurs every 4 years. This is why you sometimes see the year written as 365 1/4 days in a year)
Facts About the Calendar
There are 28 days in February; it is the shortest month of the year. When there is a leap year, the extra day is added to
the month of February, so during leap year there are 29 days in the month of February.
The following months have 30 days: April, June, September and November.
The following months have 31 days: January, March, May, July, August, October and December.
From Sunday to Saturday is 1 week.
Saturdays and Sundays are the weekend. There is usually no school on weekends.

What is weather and how does it relate to the calendar?
Weather is the way the air around you changes from throughout the year. It is the way water changes in the air. If there
were no water we wouldn’t have clouds, rain, snow, thunder or fog.
To describe weather some of the things you can say are: it’s sunny, cloudy, rainy, snowy, icy, windy or foggy.
Weather is different in different parts of the world. To describe weather over a long period of time in different places we
say “climate.” The Arctic has a cold climate while the tropical areas have hot climates.
At certain times of the year, there are certain kinds of weather that usually remain the same from year to year. We call
these seasons.
Winter - usually cold and/or stormy
Summer - warm and sunny
Spring - after winter; usually cold at night but warm during the day. The sun goes higher in the sky and the day is
longer. You set your clocks an hour ahead of time.
Autumn - also called fall. Nights are longer and cooler, usually frosty or misty in the morning.
You set your clocks back an hour.
Some places have just two seasons—wet and dry, while others have Spring, Summer, Autumn and Winter for a total of
four seasons.

The Rise & Fall of Temperature
During the course of a day the temperature rises and falls at different times. If you know
the initial temperature and are told how much the temperature has risen or fallen, you can
determine the final temperature.
Look at the first two examples, determine how we came up with the conclusion, and complete
the table.

Change Final
Temperature
Conclusion
35°F rises 12° 47°F rise means to increase, so add
12 to 35
52°F falls 10° 42°F fall means to decrease, so
subtract 10 from 52

Order of Operation
When working number sentences with more than one operation, the order in which you do them is very
important to get the correct answer.
To make it easier to remember, just remember this;
Please Excuse My Dear Aunt Shante.
first Parentheses ()
then Exponents x²
then Multiplication X
then Division ÷
then Add +
and finally Subtract -
This order should be followed from left to right (if operation is not in sentence, skip to next operation).
Example:
(5x2) + 3² - 5 =
(10) + 3² - 5 = Parentheses First
10 + 9 - 5 = Exponents Next
19-5 = Addition Next
14 = Then Subtract
117
Working with Order of Operation
Ex. 15 - 6 + 4=
9 + 4= (add and subtract from left to right which ever comes first)

1. 17 - 3 x 2 =
2. 9 ÷ 3 + 11 =
3. 12 - 3 + 2 =
4. 6 x 7 - 8 =
5. 8 + 10 ÷ 2 =
6. 5 x 3 ÷ 5
7. 8 - 8 + 8
8. 1 + 2 x 3 - 2 ÷ 2 =
Add Subtract
Multiply and Divide first!
118
Working with Exponents and Order of Operations
Remember: Please Excuse My Dear Aunt Shante
1. (5 x 4) + 6=
2. (2² + 3) ÷ 7 - 1 =
3. (30 ÷10) x 3 + 6 - 3² =
4. 7 x (2 + 1) - 4 =
5. 8 ÷ 2³ + 19 =
6. 6² + 2²
7. 4² + (5+7) x 2 - 11 =
8. (1² +2² +3² +4²)÷ (7 x 5 -32) =
