Lesson Description - Subtraction of Integers:

This lesson covers the idea of subtraction of integers. Students learn that subtracting an integer is the same as adding the opposite of the integer. For example, 2 - 4 can be changed to 2 + (-4) -- in other words, minus a positive can be changed to plus a negative -- and -7 - (-1) can be changed to -7 + (+1) -- in other words, minus a negative can be changed to plus a positive. Once the subtraction has been changed to addition, students add the integers using a number line, where a positive integer represents a move to the right, and a negative integer represents a move to the left.
