# Stage 2, mathematics, Year B – Unit 24

This unit develops the big idea that fractions represent multiple ideas and can be represented in different ways.

## Syllabus

Syllabus outcomes and content descriptors from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

Students are provided with opportunities to:

• partition, measure, label and compare lengths and wholes using fractions
• use addition and subtraction of fractions to find complementary fractions
• solve problems using equivalence and complementary fractions.
