Ds's class arrangements for next year have just been announced and i am struggling to see how it is going to work. Basically, they are mixing the youngest 5 of his year (he will be year 3), with 25 year 2s to make a mixed year 2/3 class. I am worried about there being such a small number of year 3s, and about teaching across the key stages. What do you think?
This happens in my dcs' school from Yr 3 onwards. The mix changes slightly each year. The teachers generally seem to manage just fine. I would ask them if you are worried how they plan to ensure that your ds is doing Yr 3 work and to differentiate between the Yr 2 and 3 children. I wouldn't worry until I had at least discussed that with them.
The only possible issue I would have with a mixed year 2/year 3 class is that schools seem to have fewer afternoon breaks for KS2 children and it might be a bit dispiriting for the five year 3s to see the rest of their class go out to play.
But as long as it is planned for well, which I would assume it would be, children would all be able to access the work at the right level for them.
DD1 has been in a mixed Y2/Y3 class this year which I was worried about, but it had worked out well. The only thing I would make sure about is whether those 5 Y3s are going to have full access to anything the rest of the juniors have access to - things like after school clubs and music lessons are quite easy, but things like junior shows, trips and library access can be more tricky.
