Hi all, I'm after a bit of advice for a lesson observation in the form of an OFSTED inspection (oh yes) and I want to try something out regards the format of the lesson. It's going to be on rearranging formulae, and within 20 minutes I want to be able to tick all the boxes re progress, differenation, AfL, etc etc. From the off, I'm going to try and do very little explanation myself. I'm going to give the students a set of formulae, and some rearrangements - some correct, some not. I'm going to go through each one and ask them to explain to me why they're right or wrong, and then if they're wrong, get the students to show their answers to me on whiteboards. I'll then get the students to go through an explanation if they're right. Then I'm going to get them to have a go, in pairs, at matching a set of formulae with their rearrangements. There'll be a choice of two sets, one harder than the other. Students can pick what they want to do. Then I'll display the answers and get students to mark their own. For the plenary, I was going to do a simple 'show me' task where I put a formula on the board and they show me a rearrangement. What do you reckon? Is there any way I can tweak this? Am I planning too much? Is it too dry? It's a big ask but I'm going for it to get SLT off my case and give my department some ideas on this.
