Students are provided opportunities to:

  • read, rename, represent and order numbers up to and including billions
  • interpret, compare, order and represent decimals up to thousandths
  • use informal written strategies like the area model to represent and solve division problems involving whole number remainders.

Represents numbers A – MAO-WM-01, MA3-RN-01, MA3-RN-02

  • Whole numbers: Recognise, represent and order numbers in the millions
  • Whole numbers: Apply place value to partition, regroup and rename numbers to 1 billion
  • Decimals and percentages: Recognise that the place value system can be extended beyond hundredths
  • Decimals and percentages: Compare, order and represent decimals

Represents numbers B – MAO-WM-01, MA3-RN-01

Whole numbers: Locate and represent integers on a number line

Multiplicative relations A – MAO-WM-01, MA3-MR-01

  • Determine products and factors
