Lapbooks are paper manipulatives using file folders in which students store creative summaries of their work. They can contain mini-books, printables, drawings and illustrations, diagrams, and other paper manipulatives customized to emphasize the subject of the lapbook.
Originally designed using paper manipulatives taught by Dinah Zike, author of Big Book of Books and the Big Book of Projects, lap books have been fine-tuned and explained in depth by Tami Duby in her book The Ultimate Lap Book Handbook. I had the pleasure of seeing the lapbooks that Tami's children created from preschool to high school, and they are impressive and varied. Lapbooks give a child something tangible to show friends and family and every time they show them off, they are reviewing the material that they learned in that unit or topic.
Dinah Zike's science unit studies are excellent worksheets to use in lapbooks.
