The measurements we used are:
Mouth & Teeth: 6 1/2 x 1 1/4 inches
Big eye circle: 1 3/4 inches
Small eye circle: 3/4 inches
Body & Tail: 6 1/2 x 2 1/2 inches
Legs: 2 3/4 x 1 3/4 inches
Cut out the shapes as shown from card stock, using pinking shears to achieve a serrated look along the top of the back, tail, and teeth, as well as the bottom of the legs.
Glue the small eye circle atop the larger one. Then punch 1 hole in the eye circle and 1 each in the upper jaw and body where the 2 will join together.
Glue together all the pieces except for the upper jaw, which can be attached with a paper fastener as soon as the glue dries. Coat the alligator's body with glitter glue (for scales).
Glue a straw to the back of the body for holding the alligator and another to the back of the upper jaw for opening and closing his mouth.
To cast shadows with your action puppets, simply hold the critters up in front of a desk lamp or flashlight pointed toward a wall. Then have someone turn off any other lights and let the show begin.
