Today we are going to begin talking about adding and subtracting integers. We may not make it to subtraction today, if not we will get to it tomorrow.We will be using hands on materials, the Smart Board, simple plus and minus signs, and the numberline to help us achieve our goal for the day. We will also discuss the integer rules that apply to addition and subtraction. However that is not my ultimate goal for the day.

The following video is a cute way to remember the rules for addition with integers.

The only thing you need to know for subtraction is to use the Additive Inverser (a.k.a - Add the Oppposite) When you add the opposite in the problem you will make the problem addition and then you follow the addition rules.
