Tricky building set with different tilted blocks. Only the matching colors will complete a rectangle. All 6 blocks within one shade of color (blue/red/green/yellow and purple) have the same tilt angle and therefore will also complete a rectangle.
By building and playing with the uneven blocks, children develop fine motor skills and spatial reasoning skills.
30 building blocks in a wooden frame
