The Classroom Kit is a bulk pack of Tegu Blocks perfect for both the classroom or the home playroom. Fully compatible with all other Tegu Magnetic Wooden Sets. It includes 90 blocks in 10 shapes: 8 cubes, 14 tall columns, 8 medium columns, 16 mega planks, 14 long planks, 12 short planks, 4 short angles, 4 triangles, 2 parallelograms and 8 wheels. One study found that kids who played with blocks scored higher on language tests than kids who had no blocks. Imaginative and rambunctious “free play,” as opposed to games or structured activities, is the most essential type.
