# Stage 2, mathematics, Year A – Unit 06

This 2-week unit develops the big idea that our number system extends infinitely to very large and very small numbers.

## Resource

Students are provided with opportunities to:

• read, represent and order numbers to thousands, applying place value to partition numbers up to 4-digits
• use partitioning and place value knowledge to add and subtract
• identify the relationship between addition and subtraction.

### Syllabus focus and content groups
