I cut out 10 balls total. Then I cut out stripes and spots. You can put stripes and spots on 2-3 balls, then ask how many balls have stripes and how many have spots. You can also teach same and different. Line 3 balls up and put spots on two of them and leave one without. How many balls have spots? Which ball is different? Which two balls are the same?
There are a number of ways you can teach counting. My sons love balls. Basketballs, baseballs, beach balls. If it is round they want to kick it, hit it, or throw it (actually it doesn’t have to be round for them to want to do those things). So when I teach counting I gear it toward their interests. If you have a daughter you could cut a middle hole in a circle and make bracelets. Then cut different color “beads” out and place them on the bracelets. How many bracelets have blue beads? How many have red?
