It sounds to me like you already know the answer, but you're looking to see if other people think the same way you do. A number of distinguished authors on the subject of children's reading HIGHLY recommend what you seem to be feeling in your gut. (and me and Dawn T. for what it's worth.)

I have so many questions I want to ask you. Did they give him a big list and he had to choose 3 from it or is it 3 required books? Or is it simply "suggested reading"? I think some schools do that just as a starting point for folks who don't know where to start. Does he normally enjoy reading for pleasure? Does he have any problems with reading or is he a little behind? How do they know if he really does read the books - do they test him, or do they just ask him? What happens if he doesn't read them? What if he ends up reading a lot more books, but different ones that he has chosen? What *are* these books that the school thinks rank so highly anyway? (When I look at lists of classic and award-winning children's literature, I RARELY see any of the required reading I was assigned in school, but I see a LOT of the books that I had at home. Although I don't remember how much of that was selected by my mom or how much I just gravitated to because it was displayed front cover facing out at the bookstore.) What do *you* think of the selections? Do you think you could select books that better match his interests? (I'm sorry - this is just a subject that REALLY interests me - we're addicted to books. )
I couldn't agree more with Dawn T. If your kid reads through the required books, but starts hating to read, won't you be worse off by the end of the summer? Rewards and incentives often have the opposite effect - reading becomes a chore he has to do to get the reward, instead of just reading for pleasure. (Which is why many parents HATE those book-reading contests for pizza. The kid goes into a bookstore and says "I need a book!" The salesperson asks "What are you interested in?" "I don't care - it just has to be 100 pages to count." Salesperson (or librarian, or book lover) cringes.)
It's just simple human nature to not enjoy something as much if you *have* to do it. It's even been proven that kids who are assigned to read Mark Twain in school don't enjoy it as much as the kids who just happened to read it because it was sitting on their bookshelf one day when they were bored. (Can't remember if it was Tom Sawyer or Huck Finn, but it was the *same* book, with vastly different levels of appreciation.)
And when you look at "Summer Reading" suggested for adults, it's usually the more laid-back, humorous or even "guilty pleasure" reading that you do at the pool or the beach. You can't read "War and Peace" at the beach! 10 months out of 12, the teacher gets to dictate what he HAS to read - it isn't too unreasonable to let him persue his own reading interests from June to July, is it? (In this case, just the last few weeks of summer.)
PLENTY of people who research cognitive development and how kids learn and develop HIGHLY recommend letting the kids read what interests them, and just letting them choose whatever. (OK, not Playboy magazine). Kids often start off getting something you're not crazy about (skateboarding magazines, or Captain Underpants), but once they see you're not uptight about it, not cringing or rolling your eyes or making them follow up with something YOU choose, they start to develop more sophisticated tastes naturally, even if it's not as quickly as you'd like. (Obviously, you can buy something and keep it available on a table or in the car or hand it to him when he's bored.)
If it *is* required, can you email the teacher over the summer? Do you really think that if you told the teacher that he was getting frustrated and angry and crying so you took him to the library/bookstore and let him picked what he liked, would the teacher actually have a PROBLEM with that? Really? (I shudder to think.) But even if you think he/she would, you can completely justify doing exactly this by quoting Jim Trelease, Mem Fox, or Esme Raji Codell, who have all written books on the subject of children and reading. Especially if you can't reach the teacher over the summer!
If so, there's plenty of research showing that the most avid readers are the kids who get to choose what interests them. (And - you know - the obvious stuff, like having all kinds of books around the house, frequently visit the library and let them check out as many books as they can carry, and maybe not have the TV on constantly in the background.)
Try this experiment:
Create a cozy reading nook for him with a good squashy chair and good reading light, not too bright. Go to a bookstore alone and find a book you think he would just LOVE - something that really interests him or will make him laugh out loud, and just leave it on his bed as a gift and see if he "takes the bait."
Then sit down with him and look at the "Book a Day" blog on the Planet Esme website. http://planetesme.blogspot.com/ If you can't find something that interests him there, then I will eat my hat. (Amazon.com has lots of lists made up by customers on any subject you can imagine.)
Make him a deal: he doesn't have to read anything else off the summer reading list if you can go to the library a couple of times and max out his library card. (Don't forget the audiobooks for the car.) And NEVER take a hungry kid to the library.
I sound like such an opinionated know-it-all - I apologize. And I've practically written a novel right here, and put you to sleep. It's just that I'm kinda going through a similar thing right now and it's on my mind so much.
(I'd love to know how it works out, if you don't mind responding with a private message.)
