I know this kind of thing gets done to death but....
My DC have previously been home educated, they've just started school for the first time, they've taken to it really well and seem to be enjoying it. DD Y3 seems to be doing well, she's learning new things but not finding the work too hard. So everything seems fine there.
DS Y2 seems to be doing very basic things, like counting and putting numbers in order, and he says he has a phonics lesson every day. His reading is very good for his age so I'm not sure what the benefit of doing phonics is. His maths, I think, is about average for his age - I'm surprised that a Y2 class is still doing this sort of work TBH. I don't know if it's just the teacher easing them into the new school year or if it's because he's in a mixed Y1/2 class and she's catering more for the younger group. I also don't know if I should say something - I don't want to hassle her so soon, but DS is complaining of boredom and I'm realistic enough to know that if he's bored he'll misbehave.
So is it normal to start off the year with relatively easy things until everyone's settled in and the teacher gets a feel for what the kids can do?
