Trinomial Cube

Cube du trinôme

The Trinomial Cube is an excellent way of introducing algebra to pre-school and primary / secondary school children as this cube works on various levels.

These cubes have a robust painted colour finish.

The trinomial cube is the concrete representation of (a+b+c)³ and is an indirect preparation for algebra.

The constituent parts of the cube represent the factors of the equation : a³ + b³ + c³ + a²b + a²c + ab² + ac² etc. but the young child is not exposed to this complicated algebra, s/he is occupied in rebuilding the cube by recognising colour and shape.

Later algebra work can revisit the cube as it as excellent starting point for understanding what can be a baffling subject if taught wholly in the abstract. Hence its use for older children and helping them understand mathematics in a more physical sense.

The trinomial cube is contained in a wooden box with two hinged sides and a lid.
