Origami Firefighter's Helmet

Follow the step by step instructions on the sheet to fold a firefighter’s helmet out of a single sheet of paper.   It is recommended to use an A3 size sheet of paper for this activity.  This activity can be a little tricky so some children may need the support of an adult, however some adults may also find this origami helmet tricky so why not set up a challenge - the adults against the children, who will be the first to complete their firefighter's helmet?
