Really interested to read this.
DD3 is in P3, in a P3/P4 composite class. Her teacher keeps telling me she is doing well, and "giving the P4's a run for their money".
She is still on Storyworld (last stage). The school insists each child reads every book though, so not sure how relevant that is, she reads chapter books confidently with lots of expression at home, and has done for as long as I can remember (not long, maybe a year?
)
Her spelling is atrocious - which I am OK with, because she uses complex words confidently (though she always manages her spelling homework without difficulty).
Her times tables, OK-ish, but not as confident as I'd like. My fault though, we really don't practise as much as home as we did with the others.
I am hoping it is down to a crap school which we have no choice over, rather than anything else. School is resolute in it's opinion that achievement/progress irrelevant. 
Are you worried about something OP?
