For my GTP interview I have to prepare a 30 minute lesson for KS3 aimed at level 6 pupils. It doesn`t give any more info than that. I haven`t taught any lessons before and I haven`t had any experience of planning any yet and wondered if I could get any advice from here. I understand that as it says to aim at level 6, I should start of with level 5, main work on level 6 and then push for level 7 with assistance. I am thinking that I should use the starter activity to recap and cover the level 5 stuff, then describe the method and get the kids to use the method in the main activity. and then was thinking of using an old Sats style question for the plenary. Does that sound like the right way to go. The only other problem is I am struggling to decide what to teach as I am not entirely sure of the levels. I have looked on the curriculum website but this only gives an overview. Would say plotting lines on a graph from the algebraic form be level 6? with level five being the understanding points on a graph in all four quadrants? Any advice on whether you think I am on the right lines, or any advice of what to teach would be hugely appreciated.
