Paper Pie Memory Matching Game for Thanksgiving

Game: This game would need to be altered to fit the content, but I love the idea of having a memory/matching game as part of a learning center. The pies are a punny way to incorporate circles. For my unit, I would use formulas for diameter, radius, circumference, and area instead of matching by design. For example, students would match the radius with the formula for area.

How to find formula for area of circle: 1. Mark three diameters of a paper plate 2. Cut pieces and line up like teeth *make a parallelogram!* 3. Trace outline of parallelogram 4. Use formula of parallelogram to find formula for area of circle
