We love Tree Blocks and all the innovative designs they use to turn trees into toys and educational tools. The Tree Blocks Wooden Block Math Kit will help teach your child mathematics in an engaging way with fun, hands-on learning. Like all Tree Blocks products, no trees were harmed to make this math kit. All Tree Blocks are made with the discards of managed paper forests. The Wooden Block Math Kit includes 66 Tree Blocks, a log ruler with stand, special dice, a learning deck created by a teacher, and a cotton twill sack to sum it all up.
