These 5 worksheets help to explain the effects of enlargement on the area and volume of a shape by looking at the length, area and volume ratios. This is an important topic that is often found difficult by many students.
There are three basic worksheets introducing the idea then two pages of harder word problems for extension work. The first worksheet lets students calculate the surface area and volume of simple 1cm and 2cm cubes so they can create the ratios themselves and see how the area and volume ratios derive from the length ratio. Sheets 2 and 3 require students to use the relationships between the ratios to calculate missing areas and volumes.
The two word problem sheets are similar to GCSE 9-1 exam questions.
