The double-slipped reef knot is a pretty nice shoelace knot. I prefer a more secure variant (a different tying method of the Ian's Secure Shoelace Knot/Turquoise Turtle that's a bit easier for me), but pretty much every kid should learn the double-slipped reef first. Scouts should already know it before they join!
