NUMBAT OER - Open Educational Resources

1. Introduction

This helpsheet introduces the geometry of two- and three-dimensional objects. It is accompanied by a basic 'recipe sheet' that provides the formulae for perimeters, areas and volumes, and these can also be accessed in a spreadsheet that allows you to do these calculations online. The main aim of this helpsheet is not so much to provide the ways to carry out calculations, but to explore how these are used to explore real problems.
