Hi, I have an interview for a job in Y1 next week and have to do an observed numeracy lesson on doubling (45 min) a couple of days before the interview. There are 26 children, mostly performing at expected level with 5 of them still on early learning goals. There is a TA in the class. I have taught Y1 a few years back and since then have mainly taught juniors so I'm a bit rusty. Was thinking of using socks pegged onto coathangers as starter to introduce doubling then game involving domino doubles in pairs ( lowers with TA as a group), followed by doubling song from Sing Up site. Does anyone have any other ideas please?
