# Mathematics – Multi-age – Year A – Unit 11

This two-week unit provides further develops students' knowledge, understanding and skills of place value and number representation.

Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

In this unit students will learn to:

• give, describe, and compare the position of objects using positional language
• give and follow directions to locations and from one location to another
• describe and identify the position of numbers using structured materials and formations
• recognise and describe the element of chance in events and games.

### Early Stage 1

• Use counting sequences of ones with two-digit numbers and beyond
• Represent numbers on a line
• Represent the structure of groups of ten in whole numbers
##### Representing whole numbers B –
• Use counting sequences of ones and tens flexibly
• Form, regroup and rename three-digit numbers
##### Combining and separating quantities A –
• Recognise and recall number bonds up to ten
• Use flexible strategies to solve addition and subtraction problems
• Represent equality
##### Forming groups A –
• Count in multiples using rhythmic and skip counting
