Year 7 Mathematics – Term 2 (WA Curriculum): Measurement and Geometry - Shapes, Space and Time

What this unit covers

In Term 2, Year 7 Mathematics in the WA Curriculum centres on the unit “Measurement and Geometry - Shapes, Space and Time”.

Students explore geometric properties, measurement formulas, transformations, and spatial reasoning while connecting mathematical concepts to real-world applications including time zones.

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 2

WA terms run roughly 9–11 weeks, and in 2026 Term 2 runs from Monday 20 April to Friday 3 July — 11 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.
