Today in class we got new seating plan and started a new unit. To find out what unit we were going to learn about Mr. H made us play hang man.

The New unit is Integers

An Integer is a positive or negative number.

an example of a positive integer would be +4, (+4) or just 4
an example of a negative integer would be -3, (-3)

e.g: (-6) + (+2)=-4
-= owe += have
owe 6 and have 2

To get this answer you would have to use Zero Pairs
A zero pair is a negative number plus a positive number that adds up to zero.
(-6)+(+2)=-4

This is one way to get your answer. Another way would be to use a Number Line.

The positive integers are always on the right and the negative integers are always on the left.

After learning about integers we work on a booklet for positive and negative integers.
Here are some questions:
Indicate whether each would result in a positive or negative way.
1. Spending $27: negative
2. Climbing a mountain: positive
3. Falling off a ladder: negative

Write an integer to represent each of the following.
1. Losing $10: -10
2. Finding a $100 bill: +100
3. Making a profit of $250: +250
