This project was inspired from a post on Pinterest originating with Giggles Galore, (firstname.lastname@example.org). She called these Tattle Monsters. My 1st Graders loved transforming tissue boxes into these wide mouthed Monsters. This lesson was taught by my student teacher, who pre-painted all the boxes with acrylic.
The first week, students cut zigzag teeth and printed spots with tempera paint and various sponges.
