Primary school query

[SconeofDestiny]

My DS goes to the local village National School here in rural Ireland.
He's a bright 10yr old and attended CTY classes in the summer hols for Maths, Physics and Chemistry.

He's currently in 4th class in a classroom shared with 3rd class (36 children) and one teacher. In Ireland there are Special Needs teachers but no TA's so literally, just one teacher in the classroom.

Last week's homework included revising the 1 times table (!)
This week, the 2 times table. His reading book today is from the Oxford reading tree and according to their website, it's aimed at 6-7yr olds.

Last week DS came home saying Miss x can't cope so all the class are doing the same work. (He normally never mentions anything about school so this was a bit out of the blue.)

DS loves Maths and is learning long division at home and multiplying things like 22 x 36 in his head.
He reads books from the library aimed at young teens. I know he often feels he's not learning anything at school but he did like his teacher last year as she did seem to engage him in interesting topics and discussions.

My older sister is a retired Primary School Head in the UK. She is pushing me to go and speak to the teacher/head because she says that whilst it's normal to have children at different levels in the classroom, they should be teaching them according to ability so sitting them in small groups etc and giving them slightly different work to do.
Apparently, children who are bored at school often end up messing about and getting into trouble later on.

This has got me worried.

Should I go in and speak to the teacher about the work being set or give her a few more weeks to see if things improve?

I did donate a lot of his old Enid Blyton type books to the school library previously and the Head was delighted. However, she said that they would be put into the 5th (11-12 yr olds) classroom bookcase. DS read them when he was about 6.

I don't want to cause a fuss unnecessarily but equally, is this normal and is it acceptable?

My children are in their early 20's but when they were in primary school there were 31 pupils in each of their classes and pupils were split into small groups and given work to meet each individual groups level.

Maybe give it another week or two at the most and if this is still continuing then have a word with the teacher before you have a word witht he principal. Most schools expect parents to go to the teacher first before going to the principal.

In my experience the focus is always on trying to help the children who are struggling and there are no resources and not much effort applied to children at the top. But ... if a teacher is approached they are usually quite good about providing extra more challenging work. If they aren't able to provide anything then I'd suggest agreeing to you getting some workbooks or books and agreeing with the teacher that when his work is done that he can work on these. Or that he can work on a project.

It is one of the (many) short-comings of the system and has been since I was a child.
