"Unit Bricks are terrific tools for facilitating children's developing visual-spatial and geometric skills, as well as numeracy and mathematics. In the process of playing with these building blocks, children gain a better sense of how objects and numbers fit together, exercise their advanced planning skills, and have fun -- all at the same time. I highly recommend Unit Bricks for any child wanting to learn through play!"
