Deriving area of shapes.
The idea is that students work through this PowerPoint (independently or in pairs) on computers to derive formulae to calculate areas of parallelograms, triangles, trapeziums and circles. At each stage there are questions for students to do to check their understanding. I have made it using a lot of animations so you need to be careful not to let students alter the file.
