Hi I'm reception so have PE sessions, assemblies etc but it all depends on where the child intitiated theme takes us. I try not to get hung up about it but I suppose you could say mine is around 50 -50 too. Some topics have meant more adult input (eg very active whole class discussions about the life-sized skeleton I took in) and some are more child-led (making dens outside). Often I play with the children, take a photo and then write up a comment from memory (not an observation but I feel it is better to spend time with them than worry about the silly evidence that is only there to prove I actually understand what I have seen.) The proof is only required by either OFSTED once every 3 years or the moderator once every 2 years - so I can't really justify spending time on it and I don't! It isn't the evidence that is important but what the children have actually learned and they learn more when you spend time with them either direct teaching or extending their play.
