Arithmetic Trinomial Cube

Arithmetic Trinomial Cube (Montessori)

The Montessori Arithmetic Trinomial Cube gives a concrete, hands-on representation of the algebraic identity (a + b + c)3. Unlike the standard Trinomial Cube used in Primary, this Elementary version is color-coded to show the place-value hierarchy from 1 unit to 1 million, helping children connect cubes and prisms with numerical value.

What children learn

  • Visualizes and composes (a + b + c)3 using concrete pieces before moving to abstraction.
  • Strengthens understanding of place value and hierarchical numbers (units to millions).
  • Builds foundations for algebra, factorization, and advanced Montessori math work in the Elementary classroom.

Details

  • Precisely cut, color-coded wooden cubes and prisms in a quality wooden box with a lid.
  • Designed for independent exploration and self-correction.

Age recommendation: 6–12 years (Lower & Upper Elementary; commonly introduced around 6–9 when ready for algebraic thinking).
