The Division Working Charts & Tiles set includes two large charts each measuring 81 cm x 28 cm (about 32" x 11"), one smaller chart measuring 45 cm x 23 cm (about 18" x 9"), and a colour-matched box of wooden tiles. The tiles measure 2 cm square and are used to fill in the division tables on the two charts. The charts feature a durable hardwood frame to protect their edges from wear.
