Stage 3, mathematics, Year B – Unit 21

This unit develops the big idea that our number system extends infinitely to very large and very small numbers.

Students are provided with opportunities to:

  • apply place value to partition, regroup and rename numbers to 1 billion
  • compare, order and represent decimal numbers to 3 decimal places
  • explore the link between multiplicative thinking and place value.

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

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

  • Use partitioning and place value to multiply 2-, 3- and 4-digit numbers by one-digit numbers
  • Select and apply mental and written strategies to multiply 2- and 3-digit numbers by 2-digit numbers

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

Represent and describe number patterns formed by multiples
