My kids made these visors during a class at Michaels* (Camp Creativity, which they highly recommend!), but they would be easy to recreate at home. You need a foam visor, white craft foam cut into triangle shapes, two styrofoam balls, two large google eyes, and some glue.
Kids can use white craft glue to attach the teeth but it's easier for an adult to help by using a glue gun to attach the eyes.
The triangle between the eyes is attached by cutting a slit in the triangle and in the visor.
Wait for everything to dry and you've got a fun dinosaur visor to wear while you read one of these dinosaur books...
