Have students complete the Flipbook and build it page by page. I usually have them do one page at each center or learning station. They can use the articles as a reference source to help them complete the pages of the booklet. Lastly, they cut, color, and assemble the booklet. Flip-up books can be glued or stapled inside their interactive notebooks, file folder, or a 12x18 piece of construction paper folded like a book cover.
