Circles, frustums and cylinders revision

Measure the volumes of objects

Lesson idea. This lesson is aimed at top-set, year 11 GCSE students who understand the definition of prisms, and have 'had a go at' calculating volumes and surface areas of prisms. The questions are deliberately challenging and may require a few calculation stages.

Teaching approach. This resource offer students the opportunity to engage in active learning^(ta) - measuring and calculating using large size cylinders and frustums. This lesson brings great opportunity for small group "dialogic teaching^(ta)". Open-ended and closed questioning^(ta) of students can be used to draw on their existing knowledge and extend their understanding. The teacher provides a practical commentary below.
