Mine will be geared a towards the upper grades, and what I've noticed my boys like to read. Click on any of the books to take you to the Amazon page.
First up: Percy Jackson (or anything by Rick Riordan!)
They all seem to LOVE this one!
2. Diary of a Wimpy Kid
I like this one, as it has good readability, but is presented in a good format, with cartoons interspersed throughout the pages
3. Adventure/Sports Books
I love Mike Lupica and Gordon Korman for this- they both have great, high interest books.
4. Big Nate
The boys love this one...it's not my most favorite. It's a graphic novel, but unlike Wimpy Kid, has more comics/cartoon. I like Wimpy Kid better, because it focuses more on writing. Big Nate focuses more on the comics/cartoons.
5. Non-fiction-War Stories
I have a collection of appropriate non-fiction books about the different wars- and my boys eat them up (not literally--they're a little too old for that! ;)
My boys like non-fiction, and I often see them flipping through my non-fiction bins (I have 5!)
My boys also like the Magic Tree House, The Black Lagoon (the chapter books), and Geronimo Stilton (I have a young class!)
I hope this helps all of you upper grade teachers (and lower grade teachers!) that are looking for some books for boys!
