The Binomial Cube is one of those amazing Montessori materials! It introduces abstract math concept to children as young as 4 without them even knowing it! This is a wooden box containing eight wooden cubes painted red, blue, and black. The box has a special internal hinge, which allows the sides to open out flat, permitting unhindered access to the cubes. The control is screened onto the lid. The Binomial Cube, a material from the Sensorial area of the classroom, indirectly introduces (a + b)³ to the child.
