Number > Multiplication

Australian Curriculum Version 9 Says:

Solve problems involving multiplication of larger numbers by one- or two-digit numbers, choosing efficient calculation strategies and using digital tools where appropriate; check the reasonableness of answers.

What this means

Multiplying numbers by one and two-digit numbers.

  • The use of an array is recommended as it can then be used to explain how the standard written algorithm works. This is the first time the standard written algorithm for multiplication is mentioned.
  • This is the last reference to multiplying whole numbers.

Tips

  • Digital tool: Most likely a calculator.
  • The examples shown in the elaborations show two-digit by two-digit or single-digit by three-digit multiplication.
