This sorting box includes pieces in 10 distinct shapes and 5 colors, giving children two simultaneous attributes to isolate, match, or sequence depending on where they are developmentally. It sits well in Toddler and Early Childhood environments as a foundational sorting and discrimination work that bridges sensorial exploration and early mathematical thinking. The variety of sorting criteria makes it a flexible material you can introduce gradually, starting with color alone before layering in shape as the child's classification skills mature.
