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.

Stage 2

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

Angles: Compare angles to a right angle

Two-dimensional spatial structure B – MAO-WM-01, MA2-2DS-01

2D shapes: Create two-dimensional shapes that result from combining and splitting common shapes
2D shapes: Create symmetrical patterns and shapes

Non-spatial measure B – MAO-WM-01, MA2-NSM-02

Time: Represent and interpret digital time displays
Time: Use am and pm notation

Stage 3

Geometric measure A – MAO-WM-01, MA3-GM-03

Angles: Estimate, measure and compare angles using degrees
Angles: Use a protractor to measure and identify types of angles

Geometric measure B – MAO-WM-01, MA3-GM-03

Angles: Investigate angles on a straight line and angles at a point
Angles: Investigate the relationships formed by the intersection of straight lines

Two-dimensional spatial structure B – MAO-WM-01, MA3-2DS-01
