Number > Multiplication & Division

Australian Curriculum Version 9 Says:

Multiply and divide one- and two-digit numbers, representing problems using number sentences, diagrams and arrays, and using a variety of calculation strategies.

What this means

Multiplying up to two-digit numbers. Dividing by one-digit numbers.

  • Calculation strategies; using 16 × 5 as an example, strategies might include partitioning the 16 into 10 and 6, multiplying both parts by 5 and adding the parts together (50 + 30) to achieve an answer of 80. Another strategy might involve halving 16 (8) and doubling 5 (10) and multiplying 8 by 10.
    There are many strategies, some more efficient than others.

Tip

  • Diagrams such as arrays will help to interpret multiplication and division questions. See nrich (nrich.maths.org/8773).
