Unlock loads of learning, from 1-2-3 to A-B-C! Battat’s Lock & Learn Activity Cubes are ready for fun on all fronts, and it starts with unpacking the 4 nesting cubes. Kiddos will love stacking the colorful cubes any which way to build a tower – then the learning can start! 13 sorting numbers, letters, and shapes will challenge kids’ matching skills and improve their fine-motor function as they fit them into the cubes. Once the sorting is done, it’s time for a puzzle! Kiddos will have to use the color-coded keyring to match the correct key for each cube. Unlock the cube and the fun can start all over again! Made of worry-free and durable materials, all Battat products meet or exceed EU, U. S. and Canadian safety standards.
