Whiteboard Game Spinner: A Fun Teaching Tool for Math and General Whiteboard Activities The human-sized spinner is perfect for selecting students to come to the board, making math probability or random number lessons a breeze. As a fun classroom activity, it's also great for choosing the last student to participate, who gets a special surprise - they get to spin again to pick the next student as a reward. To create this engaging teaching aid, you'll need a simple friction pad made from foam, cut into a 20mm diameter circle with a small hole in the middle. Alternatively, you can use a yellow or green kitchen sponge for a fun and colorful touch. This DIY spinner is designed to work with a larger screw, but a M4 (x10) works perfectly and self-taps easily. To add a secure hold to your whiteboard, attach a cheapo suction cup from eBay - just search for 50PCS Clear Transparent Hanger Kitchen Bathroom Suction Cup Sucker 20mm.
