What can you do with a pile of colorful trapezoid-shaped tiles? Leave it to your child's imagination and you'll both be delighted with the resulting patterns, shapes, 3-D designs... the possibilities are endless! This isn't just arts and crafts: Trapecolo requires visualization, spatial reasoning, and geometric modeling skills. Children can enjoy this toy on their own, or working collaboratively with friends and family. (Hape International, multiple participants, $24.99)
