Subject: Only adding...
This might be an odd concept to follow, but I think of integers this way: There really is no subtraction, only addition. If you can add, you can do all integer problems. Ex. 4--4 = 4+4 -4-4 = -4+-4 4-4 = 4+-4 If kids can see how to change all problems into addition, integers become much easier. Also, explain them in terms of money: "If I owe Jim $4 (-4) and I owe Sue $5 (-5) how much do I owe? $9 Well, owe is a negative thing so you are at -9. I didn't write this very well, but my class really seems to get it this way.
