This is a simple and engaging way to review integer computation. It begins with 15 addition problems using numbers between -20 and 20. Then there are 10 subtraction, 5 multiplication, and 5 division problems before the final 15 problems that mix up the operations in no particular order and contain higher numbers (mostly double digits). After the students complete the problems, they use their answers to fill in the
Halloween themed "color by number" paper. We all know students need repetition to master computational skills, but it's difficult to make it fun. This is an easy way to make the review a little more interesting.
