A wonderful addition to your "Big Question" bulletin board. Can be used in any manner you choose. One way to implement, is after having discussed the unit opener, you can lead your class in a brainstorming activity. List various responses about, "What makes a good friend", and then students can fill in the flip book with sentences and pictures (as the completed sample shown).
To assemble, simply copy the blackline masters of the cover page and page 1 back to back (opposite ends). Do the same for pages 3 and 4. Stagger the pages, fold, and staple.
