In this unit, pupils learn how the commutative and associative laws allow for calculations to be rearranged and factors multiplied in different orders and combinations to give the same product. They use this to simplify calculations and apply it in the context of calculating volume and to solve problems in a range of contexts. This learning will be developed with factorization also introduced as a strategy for solving multiplication calculations.

  1. Explain the use of the commutative and associative laws when multiplying three or more numbers
  2. Apply commutative and associative laws to simplify multiplications
  3. Explain the reasons for changing two-factor multiplication calculations to three-factor calculations
  4. Apply the commutative and associative laws to simplify volume calculations
  5. Apply the commutative and associative laws to simplify problems in a range of contexts
