POWERS

Arithmetic Trinomial Cube This cube represents the equation (a + b + c) 3 in concrete form and differs from the Trinomial Cube in that the component pieces are color-coded to represent hierarchical values from 1 unit to 1 million. This makes it possible for the child to equate an arithmetical value to each of the cubes and prisms. Contained in a hinged wooden box with lid. Item Number: 018700 • Algebraic Binomial Cube This cube for (a + b) 3 provides the basis necessary for the sensorial construction of higher powers of the same binomial: (a + b) 4 and (a + b) 5 . Contained in a hinged wooden box with lid. Item Number: 027200 • Cubing Material The Cubing Material is used to construct cubes and discover relationships between their component parts. These exercises prepare the child for abstract analysis of the binomial and trinomial cubes along with cube roots. The material consists of 1 cube and 27 squares for each of the numbers from 1–9. Includes a beechwood tray with lid. Item Number: 018900 • Multibase Material Hierarchical and geometric representation of numbers in bases 2 and 3 for counting forwards and backwards, and for converting numbers from base 10 into these bases and vice versa. Chart ordered separately. Item Number: 027000 •
