Mathematics – 3–6 – Multi-age – Year B – Unit 1

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

Mathematics K–10 Syllabus © 2023 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

Students are provided with opportunities to:

  • partition, represent and order larger numbers
  • apply place value to recognise, regroup and order whole and decimal numbers
  • explore the link between multiplicative structures and place value to solve problems.

Syllabus focus and content group

Representing numbers using place value A – MAO-WM-01, MA2-RN-01
  • Whole numbers: Read, represent and order numbers to thousands
  • Whole numbers: Apply place value to partition and regroup numbers up to 4 digits
Representing numbers using place value B – MAO-WM-01, MA2-RN-01, MA2-RN-02
  • Whole numbers: Order numbers in the thousands
  • Whole numbers: Apply place value to partition, regroup and rename numbers up to 6 digits
  • Whole numbers: Whole numbers: Recognise and represent numbers that are 10, 100 or 1000 times as large
  • Decimals: Extend the application of the place value system from whole numbers to tenths and hundredths
Multiplicative relations A – MAO-WM-01, MA2-MR-01
  • Generate and describe patterns
  • Use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10
  • Recall multiplication facts of 2 and 4, 5 and 10 and related division facts
Multiplicative relations B – MAO-WM-01, MA2-MR-01
  • Investigate number sequences involving related multiples
  • Use known number facts and strategies
  • Operate with multiples of 10
Represents numbers A – MAO-WM-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, MA3-RN-02
  • 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
