I'm not sure if your DD will be moved classes but wanted to let you know what happened to us.
My school uses 3 mesures - age in the year group, academic ablility and confidence. My bright son was academically able and born middle of the year. He stayed in reception classroom due to confidence. Had it been based soley on ability/age, he would have gone into other classroom.
While in year 1 (in reception class) he did year 1 work - not reception work. The main difference between year one in reception room and year one in other classroom was slightly MORE play (yay), slightly LESS time spent writing (suited son as he didn't enjoy written work at that point) and MORE maths work?!? He continued to be in a MORE 'held' environment also.
He became a free reader part way through the year and then left the class having made made huge strides in maths. He was also much more confident having been the older child in the class. He was able to shine and take the lead when previously the louder children had dominated floor time etc.
When the class got back together in year 2 he slotted straight in and returned to the top sets. For a short time (5 months?) the ones that moved up seemed to write a little more but it has made no long term difference at all. Son is now in year 3 and on reflection i am glad he stayed with reception teacher.
What i would say is that your DD is still very young and that she has a whole life time of schooling in front of her. Why not let her enjoy a more balanced year 1 that involves a little more access to the reception toys. She will still be covering the year 1 work I am sure. You can always ask how they are going to do this if you have any concerns.
I must add that some of the parents used to say their child had 'gone up' while my child was 'staying down'. It really was an odd thing to say as both groups were doing the same work. They maybe thought of their child as being better maybe? Their kids however were really exhausted through year one and quickly lost some of thier enthusiasm for school.
