POLYGONS

A polygon is a plane figure that is closed with thee or more line segments.

Polygons are classified based on the number of sides and angles they have.

Lines, Line Segments, and Rays

A line extends forever in both directions. A line goes on forever and ever.

A line segment is part of a line. It has two end points.

A ray extends forever in only one direction. It has one end point.

Types of Lines

Parallel Lines Perpendicular Lines

Intersecting Lines

Never

Intersect

Intersect at a 90 degree angle (right

angle)

Intersect Each Other

Angles

An acute angle is an angle that is smaller than a right angle.

An obtuse angle is an angle that is greater than a right angle.

A right angle has a square corner – a 90 degree angle.

Flips, Slides, and Turns

Does this picture show a flip, slide, or turn?

Circles Circumference is the distance

around the circle. Diameter is the line segment

that passes through the center point of the circle and touches each side of the circle.

Radius is a line segment that runs from the center point of the circle and extends to the outer edge of the circle.

The center of the circle is the middle.

PerimeterPerimeter is the distance around the

outside of a polygon.

Rounding

Rounding a number is when you take a number and "bump it up" or "bump it down" to a

nearby and "cleaner" number. A number can be rounded to any place value you want.

FRACTIONS

A fraction is a part of a whole.

Example: If I eat 1 piece of the whole pizza that was cut into 8 equal slices, I would have eaten 1/8 of the pizza.

Mixed Numbers

A fraction that is greater than one is written as a mixed number. A mixed number consists of both a whole number and a fraction!

Here is a picture of 1 whole pizza a half of another pizza. The mixed number is 1 ½ .

Practice Mixed Numbers!

In your journal, write the mixed number that each picture illustrates.

 

Odd and Even Numbers

An ODD number ends in 1, 3, 5, 7, or 9.

An EVEN number ends in 0, 2, 4, 6, or 8.

No matter how big or small the number, always look at the last digit (the ones place) to determine if the number is even or odd.

Odd and Even Numbers in Addition

Two even numbers added together will ALWAYS result in an even answer!

6 + 6 = 12 56 + 4 = 60

Two odd numbers added together will ALWAYS result in an even answer!

5 + 3 = 8 33 + 15 = 48

One even and one odd number added together will ALWAYS result in an odd answer.

4 + 3 = 7 76 + 21 = 97

Odd and Even Numbers in Subtraction

Two even numbers will ALWAYS result in an even answer when subtracted from each other!

6 - 4 = 2 56 - 4 = 52

Two odd numbers will ALWAYS result in an even answer when subtracted from each other!

5 - 3 = 2 33 -15 = 18

One even and one odd number will ALWAYS result in an odd answer when subtracted from each other.

4 - 3 = 1 76 - 21 = 45

Odd and Even Numbers in Multiplication

Two even numbers multiplied together will ALWAYS result in an even answer!

6 x 6 = 36 12 x 4 = 48

Two odd numbers multiplied together will ALWAYS result in an odd answer!

5 x 3 = 1511 x 7 = 77

One even and one odd number multiplied together will ALWAYS result in an even answer.

4 x 3 = 12 5 x 10 = 50

Odd and Even Numbers What do you remember?

- If I add two even numbers together, will my solution be odd or even?

- If I multiply an odd number and an even number, will my solution be odd or even?

- If I subtract two odd numbers, will my solution be odd or even?

- If I add and even an odd number together, will my solution be even or odd?

Finding Range

Find the range of the following data sets in your math journal.

1.) 4, 9, 0, 2, 2, 3, 8, 4

2.) 39, 10, 29, 23, 42

3.) 189, 187 , 156, 204

Range

Range – The range of a set of data determines how spread out the data is. In order to find the range, you simply follow 2 very simple steps!

Steps: 1.) Order the numbers from Least to Greatest. 2.) Take the greatest number and subtract the smallest

number. Your answer equals the RANGE! Greatest Number

- Smallest Number Range
