have you been told the levels of the children? you have really good elements to your lesson but I'm just wondering about the pitch! the evaluation of the writing and peer assessment is really good as is using real life objects! im just wondering about the pitch. see if you can find out the range of levels in the class and use levelling grids to help you target - that being said my interview lesson for the job I am in now was pitched wrong! (can't say I know exactly what they're looking for during an interview lesson!).
