**Instructions for Use**

**Buzzing with Shapes** allows students to identify shapes by number of sides.

The goal of this 2-player game is to be the first player to fill a row, column or diagonal. Spin the spinner. The number that the spinner lands on represents the number of side the shape has. Drag the number counter over a shape that has that number of sides. Remember, you want to try to have 3 counters in a row, column or diagonal.
