Sneaky Swiper [Counter from N, (N + 1, N - 1)]

Activity Type: Small Group

Counter from N (N + 1, N - 1)

Quick Description:

Children count objects in a group. The teacher takes away one and asks how many there are now, guiding children to see that removing (one) gives them the counting number before the previous counting number. This is also done by adding one. Later versions focus on adding or subtracting more than one. (Adapted From: Building Blocks ©.)
