Practicing math using triangular number families is very effective, but at our house, flash cards seem to get strewn around everywhere and I thought it would be great to have it all in one place. So, I created this number wheel, which shows each number family as you turn the top circle. With this wheel your child can learn the addition and subtraction facts in a more cohesive manner rather than as abstract facts. Simply place a finger over the number which fits with the facts you’re studying. For example, if it’s addition practice, put your finger over the largest number (with a gray background).
This is the first set, with facts up to 10. Subsequent sets are forthcoming!
