I'm getting observed this week and I'm lacking ideas for inspiration. I've had a very up and down year for personal reasons and I would like to prove that this hasn't affected my teaching abilities (nobody has ever questioned this but it would be nice to prove to myself I can still be creative!) My school is having a big push on raising numeracy standards with an emphasis on creative teaching and the focus of the observation is assessing pupil progress. I'm on unit D3 from the new framework and the lesson should be on solving problems involving capacity. I'm thinking that I will get the BAR to order containers based on estimated capacity and then decide how to test if their idea is accurate using given equipment with an emphasis on assessing their ability to estimate capacity. I'm not sure what to do with the rest of the class though, I know the HT and DHT are going to be looking for me to really challenge the children but I'm lost for ideas. Any advice would be much appreciated!
