Students are provided with opportunities to:
- partition, rename, represent and order numbers up to 6-digits
- apply place value to recognise, name and order decimals to tenths
- use multiplicative structures such as arrays to solve problems.
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: 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
