When making books with photos, sometimes I print two to a page and then fold in half. It saves on cutting and gluing.
Since these books are very popular with the kids, they need to be durable, but I don't have time to laminate them. Plus, I think it's kind of a waste of money. Laminating film is not cheap. Clear packing tape makes books like this last so much longer. Once the page is folded over, I place half of a strip of clear packing tape on the open side of one page and then fold the tape over to attach it to the other side. It attaches the two open sides together and creates a durable edge that is then ready to be bound with all the others. Again, no glue needed.

May your classroom books be ever doable and durable!
