estimate, construct and measure angles in degrees, using appropriate tools including a protractor, and relate these measures to angle names

How Bloomi helps with this

This is a NAPLAN-year topic. Bloomi teaches it with a short explainer, guided practice, and NAPLAN-style questions — every one traceable to this exact code.

What this looks like in the classroom

• using a protractor to measure angles in degrees and classifying these angles using angle names; for example, an acute angle is less than \(90\)°, an obtuse angle is more than \(90\)° and less than \(180\)°, a right angle is equal to \(90\)° and a reflex angle is more than \(180\)° and less than \(360\)°
• estimating the size of angles in the environment using a clinometer and describing the angles using angle names
• using a ruler and protractor to construct triangles, given the angle measures and side lengths
