# 3–6 multi-age, Year A – Unit 06

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.

## Syllabus outcomes and content groups

### Stage 2

#### Representing numbers using place value A – MAO-WM-01, MA2-RN-01

• 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
