Unfinished Wooden Number Puzzle with Challenge Cards

This is a hands-on wooden toy designed to introduce young learners to numbers and counting through tactile play. The puzzle helps children master early math skills, number recognition, and simple arithmetic by physically building digits.

The chunky math blocks have smooth edges and a light, unfinished natural wood tone, perfect for small hands. The set includes challenge cards that guide children through progressive learning activities and logical problem-solving.
