This is an awesome and easy craft. I saw this idea from here. What you need: empty toilet paper roll, scissors, cardstocks/empty cereal boxes and crayons/colored pencils. First I drew a dinosaur pattern onto cardstock. Or you can print the dinosaur template.
Cut out then let your kids to color/decorate the dinosaur.
Cut toilet paper roll in half as the dinosaur's legs, and cut slits on the top to hold up your dinosaur.
And here is our finished work, smiley dinosaurs!
