Count your way from early learner to kid genius! 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. They all combine to create one perfect cube! – But beware… Each shape has to be flipped in just the direction in order for them all to fit together. Get your little learner on the fast track to brilliance with the Smarty Cube 1–2–3. It's a brainteaser that makes early-learning stick!
