## Activity Introduction

Quick summary: During this lesson students investigate, estimate, identify and classify angles in the outdoors in preparation for furthering their understanding of geometry. They apply their understanding of angles to the real world by identifying a range of angles in their local environment. Students will develop communication skills as they write instructions and provide feedback.

This lesson is designed to be taught outside. It contains all the tools required for students to reap the benefits of being outdoors while learning the outcomes of the Australian Curriculum. By spending time outdoors and connecting to nature, students are more likely to care for and conserve nature as adults.

We’ve taken elements of this lesson and adapted them for remote learning. You can find this activity here.

Learning goals:

• Students recognise how to measure and estimate angles.
• Students understand how to define and classify pairs of angles as complementary, supplementary, adjacent and vertically opposite.
• Students recognise the importance of communication in order to be successful in group tasks.
• Students recognise the mental, physical and academic benefits of completing classroom activities outside.

## Teacher preparation

Overarching learning goal: By participating in this lesson students will understand how to estimate, identify and classify angles. They will be able to take their practice outdoors where they will interact with each other and apply logic while practising their angle related skills. Finally, students will recognise the mental, physical and academic benefits of completing classroom activities outside.

## Thought starter: Do trees grow up or out?

Draw a tree that contains all the angles you were asked to find in the activity and label the size and name of each angle. Here is an example to help you:
