Dado Squares truly inspire complex thought through simple design. Set a pile of Dado Squares out and stand back. What happens? Children reach out and take hold of a learning toy that's a perfect fit for busy hands, unlimited imaginations, and problem-solving growth of young minds! Little kids reason for themselves how to create incredible three-dimensional structures. Visual spatial development and problem solving come along naturally! Your child gets to know architectural principles intuitively... proportion, balance, structure and color. From 35 two-dimensional pieces, kids devise amazing three-dimensional designs. Given a few minutes with Dado Squares, they become parking garages for matchbox cars, fences for animals, angular hats, and space rockets. Every step along the way, the concentration in your child's eyes builds. Take note! This is the most impressive feature of Dado Squares - the imagination, reasoning, and visual skills that show up in playtime. Dado Squares are intended for age 3 and up.
