Kids can't resist the 150 colorful plastic triangles with the little pegs in the middle. Also comes with an 8x8" black plastic board with recessed squares for holding the triangles in place and 16 full color task cards. Terrific for working on design copy and patterning skills. Try creating your own more challenging designs. Build fine motor skills using fingertips or one of our hand tools for grasping the small built in pegs.
