Count all the squares on a checkerboard. This is a classic problem you will look at to solve it using drawings, using patterns, solving a simpler problem, and also how to solve variations of this type of problem that may pop up on math contests. Spark your math thinking!

1. Print a paper copy of a checkerboard.
2. Count all the squares on the checkerboard. Start watching this video. Pause it at 23 seconds. Use your paper copy of the board to help you. Record your answers (Hint:  1 x 1 = 64 2 x 2 = 3 x 3 = )
3. When you have a solution, watch the rest of the video to see if you have recorded the correct numbers.

Also, check out Polymachines! Youcubed has joined with Polyup to create interactive lessons where students use Poly, their AI sidekick, to explore mathematical relationships. The student goal is to modify (mod) the poly machines. Each Machine contains 1 or more Chips that are representations of the problems posed in the Machine. In each case we have thought about learning goals that are important steps in a path towards deeper understanding of mathematical concepts. It is our goal for students to explore, create and make mistakes as they help Poly learn to solve problems.
