Plan Toys 50 Unit Blocks

This 50 piece unit block set has 9 different shapes for children to build and create. The "unit"- based measurements of halves, doubles and quadruples, combined with columns, curves, buttresses and other specialized shapes, lay the foundations for basic math and geometry.

Plan Toys uses recycled preservative-free rubberwood and child-friendly water based dyes to make their toys.
