The Learning Resources Numberblocks Counting Puzzle Set introduces children to the numbers 1 to 20 in a playful way. The set consists of 60 sturdy cardboard puzzle pieces that can be put together to form 20 three-piece educational puzzles. Each puzzle features a familiar character from the Numberblocks series, the corresponding number, and the matching quantity of items to count. Thanks to the integrated self-correcting mechanism, only the correct pieces fit together, which encourages independent learning and problem-solving. This allows children aged 3 and over to easily train their fine motor skills, number recognition, and early counting abilities.
