Also, your local Scout Shop has all kinds of great books and projects that you could supplement with to do things at the "older scout" levels. You can get anything from Cub Scout to Boy Scout books there (including the BS merit badge books which are just interesting reading with project ideas in them) and all kinds of things on woodworking, astronomy, etc. There are also project kits there for building things and carving things. I'm sure, too, that your den leaders would LOVE any suggestions you have for fun things to do with the boys, even if it goes above and beyond what is required of Tigers, especially if you're able to help!
