Do you have your marble is a great way to teach youth about responsibility and also raise money – just simply give each teen a marble tell them they are responsible to keep the marble on them at all times. If you see someone that you know should have the marble (maybe at the mall, school etc.), ask them “do you have your marble?” If they don’t, they give a donation to the youth fund – you can set a price like a buck or fifty cents. Real fun!
