A 61 slide Powerpoint Presentation based on graphical representations of functions. Starts with gradients of straight lines, y=mx + c, then plotting and solving quadratics by using intersections of points, properties of quadratics, key features of quadratics (using completing the square to find turning points), followed by cubic, reciprocals, circles and trigonometric graphs. Exercises (from GCSE Rayner & CorbettMaths) and opportunities for starters embedded throughout. The Powerpoint can be used as a workbook with some modification, success criteria given clearly on each slide.
