Encourage early learning with the Smarty Cube 1-2-3 toy from Fat Brain Toys. Designed for ages 1 year and older, each uniquely-shaped block features a silicone number on one side and matching silicone dots on the other. Little fingers will love exploring the squishy textures and smooth, sturdy contours as they study each block and name their shapes and numbers. Then - Ready for the challenge? - Start by sliding the 1 block into the cube frame. Then the 2 block into the 1 block and finally the 3 block straight through the whole thing. BPA free; constructed of ABS plastic; numbers and dots made of 100% silicone.
