Level 3 · Mathematics M3.6

Perimeter, area and volume

Find the distance round a shape, the space it covers, and the space inside a box.

Change between metric units. Find the perimeter and area of rectangles, triangles, parallelograms, trapeziums and circles, and of shapes joined from them. Find the volume of a box, change cm³ into ml and litres, and find the paper that covers a box with no gaps.

For parents and teachers

For learners who can find the area of a shape on squared paper by counting squares, and who multiply and divide whole numbers on paper. In many schools this fits children of about 11 to 13, and older learners who never met area and volume can start here too. Each chapter takes one or two short sessions. A learner needs a ruler, squared paper, a pencil, and for some activities string, a tin and a pair of scissors. Every exercise has its answer and the reason for it. Each chapter also has a short page for the adult, with three questions to ask.
