This PowerPoint is a revision lesson were students revise the ability to work out y coordinates for a given quadratic curve and then draw the curve.
The lesson is structured so that they follow two examples at the board before attempting the next two by themselves, before looking at a couple of more complicated questions. Then once again having a go at a couple.
The revision lesson (as with most of my revision lessons) are designed to last at least one hour in length.
I tend to get the students to copy the examples in their book.
