Algebra and Shapes. Perimeter and Area Formulas

This power point can be used very flexibly to teach, practise or revise various algebraic processes whilst also reminding students about the basic properties of shapes.

The slides show a wide variety of shapes. For each shape students can create an expression or formula for its perimeter ( and also for the area for many of the shapes ). In doing this they can practise collecting like terms, using brackets in expressions ( and multiplying them out ). The formulas created can then be used to substitute numbers in or for rearranging work.

There are two worksheets ( with answers ) to go with the powerpoint which concentrate on creating expressions for perimeters.

GCSE 9-1 refsA1, A2, A3, A4, A5, A6, G4, G16, G17
