Use spinners to create problems using the operation of your choice! Students will benefit from practice through a hands - on game like activity that is much more fun than a worksheet. I use spinners with all sorts of math problems within the four basic operations because I want them to practice in an active engaging way. These spinners give me the chance to walk around and help students individually while they are working and unlike a worksheet, there is no "last" problem! You can have students create as many or as few problems as you want. A great way to individualize practice for your kids.
