My dd is Year 2, in Lancs, just a little further South than you may be!! and moved schools at end of Yr1 - Lancs/Merseyside. It is interesting to see the difference in schools (I am still in touch with a lot of her friends mums there), so I wouldn't worry too much, they are all so different.
DD has only just started thinking about spelling things correctly - new school has spelling tests (old school until end Yr1, didn't have these and her old friends still spell a lot of things phonetically), DD has had a lot of catching up to do with spelling, new school was much further ahead.
She knows her 2x 3x 5x 10 x and has just learnt her 4x for next week - similar in her old school, but not sure they have done 4x yet.
Adding two figure number only, both schools, starting to subtract two digits up to 100, working on subtracting teen number by nearest 10. DD can do these mentally now, but will revert to fingers now an again! Old school using number lines/squares etc., apart from top table!
Handwriting, improving!!! This was pretty bad, but old school didn't worry about, new school does handwriting practice and puts a lot of emphasis on it.
Bascially it is on the line, legible, full stops, capitals, speech marks, questions and exclamations and sometimes, if we are lucky, a comma. Working now on the possessive ' . Being aware of using adjectives and similes and good time connectives. Old school maybe doesn't work on this side of things so much, they like the output and full stops/capitals, adjectives and connectives, but don't worry about writing/spelling. (one of the things that worried me about it!).
Reading, sounds similar to dd, who does various different schemes, but gets Level 10 books (Lime I think is 11). Old school most friends Level 9, some more some less.
Honestly the range is so varied, that I don't think you will have much to worry about. If she is slightly behind in some things, she will catch up, my dd has had quite a lot to do, but has, in 8 months, with very little extra work really.
I hope the above helps a little, I was terrified at moving dd, but it was so much easier doing it than thinking about it, just don't let her pick up on your reluctance and disappointment that you are moving, or she may take that with her to her new school. I am amazed at how adaptable kids are.
