Stacking blocks without unintentionally knocking off the previously stacked one is challenging for beginning builders. Stack & Play makes stacking less frustrating and more rewarding by adding dowels and plugs to the blocks. These uniform connectors fit together easily and stay together as one block stacks on top of another. Bright colors and varying shapes support color and shape identification. Block play develops eye-hand coordination and motor control, cognition and language. Set includes 18 wooden blocks.
