This project helps your child reinforce how much 100 actually is, as well as the fact that it is 10 groups of 10.
Cut out 10 tree trunks, approximately 4-5 inches high, from brown construction paper and 10 treetops, about the size of a saucer, from green construction paper. Glue them onto the posterboard so that none of the trees or trunks overlap.
With the marker, number the tree trunks by 10s: 10, 20, 30, etc. Using the red fingerpaints, have your child make 10 fingerprint apples on each tree, then count them up to 100!
Save this poster for later. It will be an excellent tool for teaching counting by 10s!
Optionally, if you bought apples for the “teaching half” math activity, you can slice and enjoy them now or make your favorite apple-related recipe for a yummy snack during project time.
