Activity Introduction

Are you a curious kid, always thinking and asking questions like: How did they make the Sydney Harbour Bridge? Or how amazing is that humongous rainforest tree? It’s basically all about angles. So prepare yourself to get outside to check out some of these angles.

When two lines intersect, at the point of their intersection an angle is formed. Learning about angles is important, as they are the basis of geometry.

Safety advice: Conduct a risk assessment of the site before heading out. Examples of potential dangers outside include large trees with dead or dying limbs, stinging or biting insects, sunburn and dehydration. It’s also best to be prepared by having a phone and first aid kit handy.

As you’ll be learning outdoors it would be best to have an adult with you to make sure you’re keeping safe and an extra pair of hands is always handy.

Most kids will be able to complete this activity independently.

Learning outside means limitless opportunities for imagination, inspiration, curiosity and creative thinking. Kids need to keep asking ‘why’, ‘how come’ and ‘what if’. There is no better source of questions and possibilities than investigating your natural and built environment.

Part A: Identifying Types Of Angles And Their Features

Step 1. Before you can head outside to look for angles, it will be useful to refresh your knowledge of angles. You can do this by having a go at identifying, naming and describing the different types of angles and their features using the Types of Angles – Worksheet. Use a protractor to measure and label the angles you create.

You can check your answers with the Types of Angles Examples (or get your parent/caregiver to check for you). Make any necessary corrections and spend some time ensuring you have good knowledge of the different types of angles included in the worksheet.
