Spoon a layer of sauce into the bottom of the crockpot. Add about 1/3 of the cheese mixture on top. Sprinkle a small amount of ground beef over the top of the cheese. Top with a layer of uncooked lasagna noodles, breaking to make them fit. Be sure to alternate which way the noodles go with each layer. Top noodles with another layer of sauce. Repeat this process until all ingredients are used, ending with sauce.
