I created this activity for Kindergarten and 1st Grade. It can be used as an introduction to subtraction. This is a Koosh ball game with 12 slides. Each slide has a problem for them to solve. Students will be given the total number of penguins and shown a part of the group. Students can hold and drag on the penguins to create enough penguins to equal the total. They will use the pens to fill in the answers.
