Measurement – changing dimensions

How does changing dimensions affect volume and total surface area?


This investigation allows learners to see the effect on volume when you change one, two or all three dimensions. It was designed as a self-study activity (and can also be used as an assessment but there is no investigation in term 3/4) but I have also used it very successfully as the backbone of my lesson.

Learners need to be familiar with the Volume of a prism, pyramid and cylinder.

I have been a maths teacher at one of the top high schools in the country for the past 10 years. Over time I have created a lot of resources, especially slideshows. I love helping other teachers by making these resources available to them.
