Multi-age 3–6, mathematics, Year B – Unit 19

This unit develops the big idea that angles are the primary structural component of many shapes.

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.

In this 2-week unit, students are provided opportunities to:

  • recognise and describe angles as less than, equal to, about the same as or greater than a right angle (Stage 2)
  • investigate angles on a straight line, angles at a point and the relationships formed by the intersection of straight lines (Stage 3)
  • interpret digital time displays and determine the time remaining until the next hour to solve problems involving duration, using 12- and 24-hour time
  • combine and split common shapes to create other common two-dimensional shapes and rearrange them using translations, reflections and rotations.

Syllabus focus and content groups

Geometric measure B – MAO-WM-01, MA2-GM-03

Angles: Compare angles to a right angle
