We are trying to get the kids to understand that every number has a partner to get to 100. We separated the numbers into these groups: 10’s, 5’s, 1’s, 3’s, 2’s, and 4’s. Whichever one you click you will be given multiple choice answers to choose from to determine if the answer is right or wrong. We have a green text for correct and a “ding” sound, for incorrect answers it appears red and makes a “pan” sound.
