Pizza Fractions Smart Poly Busy Board helps children learn their fractions in a fun way by using pizza slices on one side and a colorful fraction bar for easy comparison on the other. Both sides include blank sections for practice and notes. Perfect for reusable learning anywhere, the write-on/wipe-off surface lets you write directly on the board and quickly wipes clean for your next session. Use with dry-erase or water-based markers and washable crayons. No lamination is needed. Heavy-duty cardboard coated with poly material is designed to be long-lasting, easy to clean and water-resistant for many years. Carry easily with the die-cut handle. Durable board includes a black, dry-erase marker (fine point).
