This is a useful way to get your students practicing math facts. I used to use these for early finishers. They would keep them in their VIP folders and work on them while waiting for the next transition.
How to Use:
Put any number in the center of the donut. Then put 5 numbers around the hole (where the actual cake of the donut would be). Students are to add the center number to each of the numbers in the donut and record their answers around the outside of the donut.
For students who are ready for more challenging problems, once you cover subtraction you can put the inside number and then the answer and have the figure out the missing addend!
