3–6 multi-age, Year A – Unit 6

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

Students are provided with opportunities to:

read, represent and order numbers up to millions
compare, order and represent decimals (Stage 3)
use partitioning and place value knowledge to add and subtract
identify the relationship between addition and subtraction.

Content in this unit is informed by the lessons in Stage 2 Year A Unit 6 and Stage 3 Year A Unit 6. Please refer to these units for additional lesson guidance.

Stage 2

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

Whole numbers: Order numbers in the thousands
Whole numbers: Apply place value to partition, regroup and rename numbers up to 6 digits

Additive relations A – MAO-WM-01, MA2-AR-01

Use the principle of equality
Select strategies flexibly to solve addition and subtraction problems of up to 3 digits

Additive relations B – MAO-WM-01, MA2-AR-01

Partition, rearrange and regroup numbers to at least 1000 to solve additive problems

Stage 3

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

Whole numbers: Recognise, represent and order numbers in the millions
