Quadratic Graphs

I’m teaching year 11 foundation classes this year and we are looking at quadratic graphs and we’ve previously looked at sequences. We have discussed some of the things they will need to be able to do well to be able to plot the graphs and I want them to see connections with the equations and the graphs such as translations of graphs. We did a lot of discussion about the difference between linear and quadratic sequences and then we looked at plotting linear graphs and the links between the sequence, the y-co-ordinate and the same with quadratic sequences. We also reviewed what we knew about negative numbers, order of operations and substitution.
