Hi Binkytub:
First off the thing that occurs here is that you care and are worried. You care enough to ask for advice - so you definitely are in your DS's corner and supportive of him, which is a huge advantage for him.
as ItLooksLikeRainDear suggested - 4b in Maths is actually fine for end of Y6 KS2 SATs - that's national expectation (see Mumsnet learning pages info on progress through NC Levels here: www.mumsnet.com/learning/assessment/progress-through-national-curriculum-levels).
So the issue is the reading. Whether it's assuming the role of class clown, a learning difficulty, or it's just not his thing is something you can explore in the coming weeks. One thing I did pick up is you said 'He's always disliked English despite us reading to him daily and encouraging him as much as we can...' Now that sounds like it's been a struggle all along and that you're doing his work a bit too much.
Maybe what you should be doing is getting him to read to you more.
Can he read out loud well? confidently?
What does he enjoy reading? Can you encourage more of that?
Have you considered graphic novels? Comics? [suprisingly they do build vocabulary - e.g. DD1 Y5 came home at end of first day of school this year and I asked her how was it? She informed me 'her arch nemesis' was sitting at her general work table. Well done Marvel Comics!].
We have had real struggles with DD1 regarding reading - it hasn't come easily and she hates (really hates) reading out loud. We've tried 5 things with this:
- We've explained we think it's important she improves.
- We've ensured she has access to a range of reading materials (magazines, books, comic books, etc...)
- We've also got her writing (letters, postcards, Christmas cards, etc... so she's thinking about expressing herself) - this is in the context of no writing homework from our school.
- We've found taking turns reading - one page from her, another from me, and if she's reading well and seems a bit tired, I may finish out the chapter.
- you can't see the movie/ DVD until you've read it (works great with books like Harry Potter, Babe or Holes). With the Hobbit (which is difficult language - DD gets her to read obviously easier passages, and he does bulk of reading - but this is about her listening to the pattern of language and broadening vocabulary - oh and DH reliving his youth).
It's been a long slow struggle - but our feeling is it is one worth having. It does take up some of your time, but I think it is important to try to get your DS to a point where he can easily engage with Senior School work, or ultimately weak reading skills will let him down.
