Early Childhood - Trinomial Cube
Look at that focus! The binomial cube, when first introduced to the child, is presented as a challenging, three-dimensional puzzle. The cube is made up of a number of colored blocks, which fit together in a specific way. Assembling it uses a child's fine-motor skills and requires the ability to discriminate between the blocks based on multiple characteristics. Some blocks have one color, others have two, and some blocks are cubes, while others are rectangular prisms. This makes the binomial cube a more complex sensorial material, and it requires organized thinking to master. The binomial cube's big brother, the trinomial cube, is a child's more complex next step.
Like other sensorial materials, the binomial and trinomial cubes are self-correcting: when properly assembled, the blocks form a cube that fits perfectly inside of its wooden box. Even if the cube is built outside of its box, visual cues alert the child to any errors they might have made.
