Rocking Numberlines is an activity to do with your kids to teach them how to use a number line or to review this tool. There are several different number lines to print off and let your kids use. There are two books. One has just equations and the other is a bit more difficult using word problems. There is a smart board that can also be purchased to introduce number lines to your kids.
I created this for Rock your School but it can be used at any time.
