Hi 24 again:
DD1 was in this boat in Y2. Like your DS - she was behind others and I think as a parent going into reading mornings I found it really shocking to see what other children of a similar age were capable of doing and upsetting that DD1 just didn't seem to get it.
Some things that I've discovered over the years that seem to help:
If your school uses jolly phonics the workbooks (although a bit young for a Y2) these really do help with learning letter sounds and writing skills
Oxford Owl: www.oxfordowl.co.uk - has all sorts of information about supporting learning to read at home:
---------
Also there are free e-books banded by age: www.oxfordowl.co.uk/home/reading-owl/find-a-book/library-page?view=&agegroup=0&book=1&booktype=all&series=all# - so if your DC responds better to a computer than ye olde fashioned hard back/ paperback book - this may help.
------------
Don't just have them read to you. We found that by a bit of trickery we could encourage reading by playing the you do this little thing and I'll read a paragraph/ a page/ a chapter.
For example: I had this thing where DD1 was asked to read a whole sentence perfectly and if she did I read the next paragraph.
We built up to whole paragraphs - so if DD1 read a whole paragraph well - I had to read the next page.
-------
Take turns reading. Or read a story he's ready for but skill-wise can't read for himself. We tend to do this at the weekend - nice to make the weekend reading different and something a bit special.
----
No seeing the movie without reading the book.
Brilliant for films like the Harry Potter series, The Hobbit, Charlotte's Web, Sheep pig/ BABE, Roald Dahl stories, etc....
------
Comics/ Graphic novels. It sounds like it shouldn't work but DD1 was really into Pokemon and begged and begged for a comic. DH weakened but our reward was that at the start of Y5 she announced that X, her 'arch nemesis', was sitting on her table for start of the day. I can assure you arch nemesis could only have come from that comic!
------
Out and about reading. Just simple things - like road signs, directions, back of cereal boxes.
We had DD1 read the instructions for making a gingerbread house for Christmas when in Y3. Also made her do all the measuring and convert from teaspoons & tablespoons to ml. (that was just because we're a bit evil really!).
------
Children's magazines are great for reading - get a magazine of a show they like. They're pricey yeah - but there usually is tons of reading there and often educational games too!
-----
Video games:
Chose a game for DS or Wii/ Play Station or PC that has a lot of text and make them read it. Play it together but get them reading the clues/ dialogue. DH played lego Batman with DD1 which involved a lot of reading - apparently (not sure if he and DD1 were spinning a line there).
------
Board games involving reading are a good idea - monopoly ticks all those boxes.
-----
Match Attack style cards with points for various abilities - involves a lot of reading/ and calculating.
------
Competitions:
Have them enter competitions but make them read the instructions and write off (not e-mail) to them
-------
get them writing: thank you cards, post cards, letters to father Christmas. We found with DD1 working on writing fed into working on reading. Some of our work just working on writing joined up letters better made a big difference with reading - we used spelling lists from school for DD1 (but later with DD2 found Collins Easy Learning Writing series).
---------
For you my advice is this - keep positive. Keep him believing that you are confident he'll get there in the end. DD1 was dire and dreaded reading out loud (can't say the letter 'r' well) - but work with us at home and joining a reading recovery scheme in Year 4 at school with a great TA leading it really made a difference.
At school - ask that your DS is put forward for any reading recovery/ extra reading schemes they have going. They may say no (there may be others in more need) but if you keep letting them know you're concerned they will listen (i.e. we started asking in Y2 and didn't get intervention until Y4, but we did in the end).
Over the summer try and see what is going on at your local library or main library. There usually are tons of reading schemes/ story time type events. Really important to keep that reading going on over the holidays/ half-term breaks. Treat it as a muscle that needs regular exercise.
