## Activity Introduction

Quick summary: During this lesson students investigate, measure and use formulas outdoors in preparation for furthering their understanding in the topic of geometry. They apply their understanding of perimeter, area and volume to real world situations by looking for and recording a range of shapes around their school. Students will develop communication skills as they justify answers and reflect on the topic.

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.

Learning goals:

• Students investigate and determine volumes and areas of 2D and 3D shapes by considering the individual solids from which they are constructed.
• Students recognise how geometry skills can be applied to real world situations.
• Students recognise the mental, physical and academic benefits of completing classroom activities outside.

## Teacher preparation

Overarching learning goal: Students will investigate and determine volumes and areas of 2D and 3D shapes by considering the individual solids from which they are constructed. They will recognise how geometry skills can be applied to real world situations, and will identify the mental, physical and academic benefits of completing classroom activities outside.
