Integer Warm Up: Monday!Write out the alphabet assigning integer values to each
letter with A = -13, B= -12, C= -11…
Note there is not zero, skip zero and go to one when you get to the letter N. N should be positive one!
Now tell me what the following would be worth if adding:
• Your name• Your Special Someone’s name ( if it is
positive, it is a love match!)• The month you were born• A word with the smallest value posible• A word with the largest value possible

Create Properties Cubes, Test Friday• Review Slides: Fraction, decimal,
percent…• Homework: Worksheet or sort Monday
through Thursday, Test on Properties Friday
+ = +
•Numbers change places
•Look at the order on the left versus the order on the right side of the equal sign.
•Works only with ADDING and MULTIPLICATION!!!
( x )x = (x )x
• The numbers that are grouped together changed. Look inside the ( ).
•There are different friends paired together on the left side versus the right side.
•Be careful who you “associate” with!!!
•Works only with ADITION and MULTIPLICATION!!
( + )= +x x
How many do you have on the left versus the right?
• The number outside the parenthesis is distributed to each of the numbers inside.
•“Distribute” means to hand-out.
•You have two operations happening in the same problem!!!
X 1=
+ 0 =
What can you multiply or add
to a number and
not change the number?
•Any number times 1 equals the number.
•Any number plus 0 equals the number.
•Your “Identity” is who you are…. Do not let that change!!!!
+ = 0
x =1
What can you add to a number
and get 0?
What can you multiply a
number by and get 1?
• Any number plus it’s opposite equals zero.• Any number times its reciprocal equals one.•Multiplicative Inverse and Reciprocal are the same…FLIP!!!
