For the little builder with a flair for architecture and/or modern art, the Dado Squares are a perfect choice. As the cousin to the oh-so-popular Dado Cubes, Dado Squares allow you to create countless three dimensional structures that challenge your spatial reasoning and force you to problem solve – skills that are not only essential to development but a lot of fun too. Each set features 35 three inch squares and can be used to create structures over 3 feet high.
