This SMART Notebook lesson is set up as a Koosh ball game. This works great for students who are learning perimeter. Some of the sides are not labeled on purpose. Students will need to know how to figure out the length of the opposite side. If your students are just starting perimeter, you can fill in the missing numbers as needed.
There are 12 penguins to select. Each penguin has a perimeter problem. After the students solve the problem, they can move the penguin at the bottom to reveal the answer. Simply touch the fish to go back to the Koosh ball game board.
