So I have 2 interviews next week and have been told that in one I will be giving a 30 minute lesson and in teh other a 20 minute lesson. How much should I be aiming to get through in this? One activity? Should I be aiming for a 3 part lesson with the 30 minute lesson? Sorry lots of questions but I always had it in my head that I would teach a full 50-60 minute lesson at interview.
