I get to spend quite a bit of time with 11 year old scouts. I make it a point to teach them how to safely start a fire in as many ways as possible. The only things I don't allow (also against scouting guidelines) are flammable gasses or liquids. We use matches, lighters (butane and zippo), flint and steel, magnesium fire starter, steel wool and a battery, sunshine through a lens, sunshine off the polished curved bottom of a soda can, sunshine through ziplock bag of water, hand drill and bow drill, and using a fire piston. A fire piston is one of the most impressive ways to start a fire in front of an audience. I have a clear fire piston similar to this one so everyone can clearly see the "flash" as the tinder starts.

I also teach how to make char cloth, and how to find and prepare tinder and fuel without using any tools. In fact, one of the best fire starters are Fritos. They light easily and burn a long time.
Having the skill to safely start and maintain a fire is, in my opinion, an absolute necessity if you spend any time in the outdoors.
