Donor's Choose has been fabulous for my class. I've put up four projects and they've all been funded (usually pretty quickly). We've gotten cameras, copies of The Dot for Dot Day, awesome chairs, and now books by Jan Thomas and Mo Willems.
I pulled the stack out and showed them one-by-one to my students. There were many gasps, cries of "I've read that book!" and much making of the connection sign (thumb and finger out pointing at yourself and then the other person, back and forth to show a connection between you). I wish I recorded that part.
After we oohed and aahed over the books I put them all out on a table and kiddos grabbed one and found a place to read. When they finished one they put it back and got another. They could have done it all day. It was a book celebration. I did record a bit of that.
