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. Designs are improvised and revised. 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. At last - the masterwork is finished! Then come genuine smiles and beckons to "Look!" - at a small person, beaming with pride, over effort well spent. 35-piece set Includes 35 Plastic Interlocking Dado Squares Recommended for 1 or more players, ages 3 and up WARNING: CHOKING HAZARD - Small parts Not for children under 3 years of age Domestic Product Specifications Package dimensions: 3.63 in x 3.63 in x 3.5 in Material & Care Plastic Wipe clean with dry or damp cloth
