I pinned this because fan book trailers are widely popular online. This might be a terrific project for a TAB group because they learn how to sell a story through photos. Uploaded videos could be used to promote participation in TAB.
Why have a regular bookmark when you can have one that includes a book trailer? What a GREAT alternative to a book report -- have them create a book trailer, link it to a QR code & then print & make available to the class :)
