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. Flipbooks can be glued or stapled inside their interactive notebooks, file folder, or a 12x18 piece of construction paper folded like a book cover.
