Math Blocks

SumBlox are an innovative way to develop math skills. Learning to count, add, subtract, multiply and much more is as simple as stacking building blocks. SumBlox are solid wood stacking number blocks designed to improve numeracy and make learning more accessible, more fun, and more exciting. They encourage both hand-eye coordination and improve motor skills. Smaller sets of SumBlox will introduce individual children to learning with SumBlox and larger sets allow exploration of more complex concepts, and further cooperation with other learners. There is endless potential to learn with building blocks, and the freedom to create something beautiful is confined only to your imagination! Currently sold around the world.
