How do I crate-train my dog?

I have a German Shepherd Labrador Retriever Mix 5 month old puppy that is a bundle of joy, love, and energy. Unfortunately, in the mornings I have class and I can't keep him out of his kennel because he likes to get into things (crayons, pencils, and his favorite, paper towels). I really would love for him to be kennel/crate trained because I have to bathe him every time he gets out because he pees in the kennel. He also wails while inside the the kennel. Very loudly! I leave early in the mornings and he ends up waking everyone up, including neighbors. I don't want him to be in agony and I don't want my family/neighbors to get fed up with my bundle of joy. Help?
