Circles, frustums and cylinders revision

Lesson idea. This lesson is aimed at year 11 GCSE students in tops sets who have a solid understanding of the definition of prisms, and have already had a go at calculating some volumes and surface areas of prisms. The questions are deliberately challenging and some have a few calculation stages. At the beginning of the lesson each group of students should be assigned a drum. They are then required to complete the set of questions associated with that drum, before starting to work on another drum (Something like circle training). It is a good idea to have a few spare drums for those who are quick to complete their task and are keen to move on.

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.
