This Creative Puzzle is a shape puzzle and building block set in one. It will be played with throughout childhood because it can be discovered and rediscovered over and over again. The first discovery is the different shapes: What does it feel like? When children know their colors, the blocks will be sorted by color. Later, children will stack and build with the blocks (which are the same thickness as the Grimm's 4x4 sets). Fine motor skills, eye-hand coordination, differentiation and spatial thinking skills are developed. 23 pieces in a wooden frame. Materials: lime wood, non-toxic water based color stain/non-toxic plant based oil finish.
