 Today
I am working with integers.
 So
that I can add integers with the same
or different signs.

know I’ve got it if I can accurately
solve the following expression.

 Absolute
Value - The distance of a number
from zero on a number line. Absolute value
is always positive.
Inverse – The opposite of a number.
The sum is always zero.
 Integer
– The set of whole numbers and their
opposites. … -3, -2, -1, 0, 1, 2, 3 …
You can use colored counters to add positive
integers and to add negative integers.
=1
= -1
3+4
How many counters are there in total?
We can use negative counters to add two
negative numbers.
-5 + (-3)
How many counters are there in total?
absolute values of the integers and use the
sign of the integers for the sum.
Model 4 + (-3)
Model -7 + 5
You can use colored counters to model adding integers with different
signs. When you add a positive integer and a negative integer, the
result is 0. One red and one yellow counter form a zero pair.
=1
= -1
1 + (-1) = 0
Model 3 + (-2)
What is left when you remove the zero pairs?
