Help young kids practice matching, sorting, stacking, and more with this skill-building puzzle! Improve coordination and fine motor skills while matching six familiar shapes to corresponding holes in the Earth base. Each shape can only fit through one hole, helping children self-correct as they go. The bright rainbow pieces can be stacked, rearranged, and sorted, keeping kids engaged in learning. When playtime is over, all of the pieces fit easily into the bottom bowl for storage.
