I've been sharing a few of my methods for putting classroom books together. I want them durable, inexpensive, and enticing. This particular tip is one that brings out the oohs and ahhs from my readers.
After printing off the child's page and glueing it to construction paper, I use clear packing tape to adhere each page to the next. I leave a very tiny space between each page and attach tape to both the front and the back. Then when I close the book, it folds up like an accordion. The kids love stretching out the book when they read it, although for some, putting it back together presents a challenge. :)
If you check out the labels on the right side of my blog, and click on "classroom books" you'll find additional classroom book making tips as well as several types of books that I've made in my room.
