My son loves paper airplane so this was a no-brainer! The template made the activity super easy and my son had a blast with the helicopter. The template provided two cut outs so we made the second and tested different modification to see which made one faster than the other which was really fun and educational. He played with them all afternoon and even colored them with crayons which kept him busy longer. Great easy activity which only needed a little parental supervision in the beginning to print and cut the template.
