We just got back from a two week vacation in Colorado. We stayed in a cabin that backed up against the national forest up at 9500 feet.
I have two daughters, 9 and 12. When we hike they always wear a backpack with their own survival gear and water and a few snacks. I encouraged the girls to build shelters in the forest behind our house just to see what they would build. There was plenty of dead wood laying on the ground. The girls both came up with decent shelters but what surprised me is how much cordage they used. I gave them a spool of small nylon cord like is used for trot lines. They used a ton of it. I need to work with them on knots but I learned that instead of a small amount of paracord in their kits, I need to include a spool of nylon cord. Also, they didn't fair to well with plastic trash bags. I will try to come up with some light tarps for them next time.
Just as you can learn a lot by doing things yourselves, you can better equip you kids by watching and teaching them. You have to let them try and fail a few times before they want to learn but it was a fun time for all of us. Oh, minor cuts are major learning experiences for kids.
