The trinomial cube is an excellent way to introduce / teach algebra to both preschoolers and elementary school students, because this cube can be used on many levels.
The trinomial cube is the physical (concrete) representation of the algebraic formula (a + b + c) 3. The factors of the equation are represented by cubes and prisms: a3 + b3 + c3 + 3ba2 + 3ca2 + 3ab2 + 3ac2 + 3cb2 + 3bc2 + 6abc, but preschoolers do not know this mathematical formula, they focus only on reconstructing the cube by recognizing colors and of shapes.
Later, the use of the trinomial cube by primary school children will help them to understand algebra in a physical, visual sense, and not to remain only in the abstract where mathematics can only remain an enigma.
The trinomial cube is stored in a wooden box with a lid.
This product is a teaching material, not a toy. Not recommended for children under 3 years of age without supervised by an adult.
