I read the book Wonder by R.J. Palacio to my grade 4 class last year, they really enjoyed it and it brought up many great discussions. You can link it to the language curriculum as well as it ties in nicely with the Health Education curriculum as well.
If you’re interested in promoting the book to your students feel free to use this book talk I made:

Reading and appeal levels:

As a fun activity while reading the book I had the students pretend “tweet” as one of the characters on these iPhone stickies/Post-it notes I found at the dollar store (in less than 140 characters of course!). My colleague Laura did a similar activity with these sticky notes to practice chapter summaries in less than 140 characters. Oh what us teachers can do with dollar store goodies! 🙂 

Last June I “real” tweeted out a photo of their stickies:

I haven’t been able to find these iPhone Post-it notepads at my local dollar store lately, so I decided to create my own, they aren’t sticky, but who doesn’t have a glue stick? Feel free to download them and use for your own classes. Please comment below and let me know what you used them for! I added one with lines to help the littlest tweeters.
