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. Journey into ice-covered waters with this set. Young explorers can follow the footprints of penguins and polar bears to their native habitats, chill out with the seals by the shore, and go on exciting whale watches. Using the click-together shapes, kids can create their own environments filled with glaciers, mountains, and animals native to colder climates. 25 pieces in all: 8 small squares; 4 patterned isosceles triangles; 4 patterned equilateral triangles; 4 quarter circles; 1 each of penguin, seal and whale animals, plus 2 polar bear animals. Compatible with other Magna-Tiles sets. For ages 3 and up.
