Volumes of Prisms starter

A power point for volumes of prism, good if you have some boards. Starter is all volumes of cuboids, which can be done firstly by counting cubes then by finding surface area. Then an animation showing how to find the volume of a prism with a more complicated surface area. There are two example, one listening testple where I ask students to be quiet, then a questions testple where they are encouraged to ask question, I did this because this group was driving me barmy and not letting me finish a sentence without jumping in and asking a question.
