Year 7 Mathematics – Term 4 (WA Curriculum): Numbers, Algebra and Geometric Relationships

What this unit covers

In Term 4, Year 7 Mathematics in the WA Curriculum centres on the unit “Numbers, Algebra and Geometric Relationships”.

Students explore equivalent fractions, decimals and percentages, develop integer operations, investigate algebraic expressions and equations, and analyze geometric properties including angles, area, volume and transformations.

Curriculum codes in this unit

Content codes:

Reading the codes: WA codes (the ones starting with WA) pack the year level, learning area, strand and content number into one string, while the national Australian Curriculum v9 uses a different anatomy that starts with AC9 — same content family, different labels. Our complete WA Curriculum guide decodes both, character by character.

Planning notes for Term 4

WA terms run roughly 9–11 weeks, and in 2026 Term 4 runs from Monday 12 October to Thursday 17 December — 10 weeks for WA public schools. With 30 lessons in this unit, that leaves breathing room for assessment, moderation and the weeks that disappear to carnivals, camps and public holidays — plan the assessable work to land two to three weeks before the end of term rather than in the final week.
