I took a graduate class last fall in bookmaking....NOT SCRAPBOOKING. While we did several versions of binding and construction, not all were applicable to elementary Art....several, however were. This is a simple pop-up that may be used 3-5 grades, providing you work slowly.
To start, you need 2 bookends, about 6''x4'', of some heavy poster board. Next cut a long strip of heavy paper for the folded pages. Pleat it accordian style to fit inside the ends. The paper should be slightly smaller than the bookends. On each outward fold , cut a small design that will ''pop''.
The inside paper that is to be folded needs to be long enough to make at least 4-5 cutouts, so you will need 8-10 pages, plus 2 more pages to glue to the bookends.
For the bookmaking class, we used special glue, but a cheaper substitute is paste...yes, the stuff none of us buy anymore.
