Unit 10: Shapes and Sizes

10 Introduction

This unit is about shapes and considers how some of their properties (such as area or volume) can be measured. It is a practical unit, so you will need some basic equipment to tackle some of the activities—a ruler, scissors, glue, a piece of thin cardboard (for example, from an empty cereal box), and a sheet of graph paper. [ The word geometry comes from two Greek words— “geo” means earth and “metros’’ means measurement. ]
