Hi Grey Ted we have opened our Unit this September (formed from 3 classrooms linked by sliding doors and linked outside areas too, catering for full time reception, partime reception and nursery children) It did take a lot of 'mind wrestling' and we are still tweaking the way it works but so far everyone seems quite happy and the HT keeps showing us off to any visitor who will look! At the moment all children have 'Class Base' time (grouped by chronological age) first thing till 9.40, then we all open our doors and gardens for integrated provision for one hour - children can move around and access whatever they want in any area, then class base again till lunch (or 11.30 home time for nursery). This is repeated as far as possible in afternoon. During open doors time each class has a few children wearing PE type bands (ours are bright yellow!) and any adult who works/plays with these children makes notes/ takes photos etc to give to Class Base teacher later. We keep the same 'banded' children for a week, so after 3 weeks they have all been 'special' and should have had good obs made in a range of CIL activities.As FS leader I would like to increase the amount of open door time, so will be working towards this once people are comfortable with new things eg. we now don't go to assemblies or whole school breaks. We have unit meetings every week to discuss planning and anything else eg. peer observations focus. There are 3 teachers and 3 TAs and 66 children at the moment, but this will increase in Jan to a max of 86 am / pm. We share our resources and at first all planned from the same 2 week plan, but as classes are forming their own identities we are planning more to suit each group's interests. This could become quite diverse, but maybe because they have their open doors times, children seem to have linked interests/ needs so all teachers are planning similar themes anyway eg. this week it was Bears, Bear Hunt, rhyming and rhythmic stories. Hope this has helped a bit - let me know if you have any more questions!
