Balance Math vs Classroom Spinners

Part of the Math Practice Tools CFS Bundle Practice Addition and Subtraction concepts. Drag number tiles to each of the balances to exlore or create a problem for a friend. Or, press the "New Problem" button to have Balance Math create a problem for you. Then, your job is to make both sides balance. You may add tiles to each balance or remove tiles. As you add or remove tiles you'll see >,<, or =. There are 10 copies of each Number Tile. You have the Option to set which balance to use for a problem, which number tiles to use, and whether or not to hide a set of number tiles after a problem is displayed.

Classroom Spinners is a collection of spinners specifically designed for educators. Using a slider the spinner can be changed to accommodate a variety of setups: 3, 4, 5, 6, 8 or 10 sections. Sections can be labelled with either numbers or letters. Use Classroom Spinners to conduct probability experiments by spinning the spinner a specific number of times. With your students compare how the experimental probability compares with the theoretical probability?
