Magna-Tiles combine magnets, science and fun! Thin geometric shapes feature magnets on the edges that always attract to other pieces, even when the pieces are flipped around. This allows using 2D pieces to create 3D objects. The small size is great for little hands. Magna-tiles are also helpful for teaching pattern and shape recognition; symmetry; fine motor skills; sorting & stacking; and even magnetic properties. This set contains bright colors and even magnetic tiles in motion, allowing you and your children to build anything from a high-rise city skyline to a bustling colony in outer space. 110 pieces in all: 2 large squares; 56 small squares; 12 equilateral triangles; 12 right triangles; 10 isosceles triangles; 2 wheeled chassis; 1 door; 1 rectangle; 2 stairs; 4 quarter circles; 1 spinner; 6 windows and 1 arch. Compatible with other Magna-Tiles sets. For ages 3 and up.
