In our notebooks we first made sure we could generalize the real rules for adding integers. Then students took turns creating an integer subtraction problem. We then discussed all the possible options for answers.
I shared a major math moment with the class as I remembered learning this when I was in 7th grade and subtracting integers was a devastating moment for me. I remember the confusion and the discomfort. Most of all I remember the help I got from my teacher. So I shared a major hint that he shared with me.
"ADD THE OPPOSITE"
When subtracting integers change the subtraction (-) sign to (+) and then change the 2nd integer to its opposite. At that point you can follow the addition rules for integers.
