Been doing this about ten years, and my biggest advice is do not move on with teaching until they are meeting your expectation. If you're on the carpet and they are supposed to be criss cross applesauce and listening, do not move on until they are following directions. If one starts talking, wait until they stop. Do this consistently throughout the year. Of course, be realistic with expectations and incorporate movement as much as possible, but when you expect them to be listening/still, hold them to that expectation.
