The booklet includes naming and estimating angles, angles in everyday objects, reading a protractor, estimating and measuring, drawing angles, and finding unknown angles on a straight line, in a right angle and at a point.

A classroom mystery with a purpose

In The Case of the Mixed-up Protractor, students use clues to find Leo’s incorrect measurements and explain which scale he should have read. A skate park plan gives the angle work a practical context.

What you receive

50 editable teacher slides, a matching teacher PDF and a 15-page A4 booklet. Both the colour and black & white booklets come as PDFs and editable PowerPoints. Teacher notes, worked answers, instructions and fonts are included.

Differentiation and curriculum

The pack offers Getting started, On track and Challenge options. The main angle measurement work supports NSW Stage 3 MA3-GM-03. The vertically opposite angles section is clearly marked Extension (Stage 4) so you can choose whether to use it.

Using the files

Open the .pptx files in PowerPoint or import them into Google Slides. The clickable menu and answer links work in presentation mode. Print student worksheets at A4 actual size when students will measure the diagrams.
