Collaborative learning comes to life with the Spin and Write Pyramid! This rotating, four-sided, dry-erase board lets students of all ages collaborate, game, share ideas, sequence, and so much more. Made of injection molded plastic, it is easy-to-clean with no ghosting and a wipe-off surface. Each dry-erase triangle has a color-coded frame in case you want to keep track of the action, assign a color to a student or categorize. The four-sided board smoothly rotates and has a braking mechanism for those times when you want it to be stationary.Details:White with color coded frames10.875" x 8.5" (27.623cm x 21.59cm) each side of the pyramidfour-sided pyramidPlastic
