For the Grade 3 curriculum, I use this as a giant floor puzzle to introduce the ear to students and point out the mechanical features. Students can also make their Human Ear Diagram on their own with the 8.5x11 puzzle. Pieces can be cut up, arranged, and glued onto a separate piece of paper to be put into notebooks of binders.
*only pieces of the puzzle with images on them are enlarged so the giant puzzle will have no piece for all white areas.
Enjoy this lesson with your students!
