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
