WebThe Binomial Cube, a material from the Sensorial area of the classroom, indirectly introduces (a + b)³ to the child. (a + b)³ might not typically be a concept one would think could be presented to the young child, but Montessori felt differently. This mathematical thought is presented in a concrete, visual way through the Binomial Cube. Webx - 3y + 1; 5x 2 y; 14; etc.. are not examples of binomials, as the first expression contains three terms and the rest contain a single term. In the previous chapter (but not only), we also have explained how to expand the square and the cube of a binomial.
