Print out a copy of the Tyrannosaurus rex template.
If you printed the T. rex on cardstock, go to the next step. If you used regular paper, paste the printed template onto thin cardboard (like an old cereal box).
Using crayons or markers, decorate the T. rex. No one knows what colors the dinosaur were, so anything goes.
Cut out the pieces and make sure to cut along the thick lines where the legs and arms attach to the body.
