MATHEMATICS

The Power of 3 Cube consists of a dissected cube in 13 pieces painted yellow, green and white.

Demonstrates the power of 3 by progressively tripling the previous piece, starting with a two centimeter cube. That cube is then triples with two similar cubes. Those three cubes are then tripled with two 6 x 2 x 2 centimeter prisms, eventually creating an 18 centimeter cube.

The wooden tray is included.

Algebraic Peg Board with Pegs is used for demonstrating the mechanism of finding the square root.

The whole set includes  Wooden Algebraic Peg Board and plastic color-coded pegs and cups stored in a wooden box with lid.

The Small Square Root Board is used by the children to build squares and to extract square roots. The wooden board contains 225 indentations for working square roots. Included with the board is a box of 100 each green, blue and red beads.

These Patterns serve as guides when extracting square root on the Algebraic Peg Board. The material consists of four plastic cards with silk-screened square root patterns in the three hierarchical colours. High quality!    

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.

Algebraic Binomial 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.

The Cubing Material is used to make cubes and discover relationships between their component parts.

Consists of 1 cube and 27 squares for each of the numbers from 1–9.

Includes a wooden tray with lid.
