Where should you be right now? If you are on track, December starts with Session 48. If you are significantly behind, consider the following to be the essential lessons: Sessions 29, 33, 35, 36, & 40, and 26, 27, & 31 if you have time. If you are in a state with a Supplement, you need to add to this list the Sessions in the gray boxes. If you are behind, use only the first two or three days to change over your calendar in Number Corner. If you are teaching half-day sessions, are you taking a lot of your math periods up with Work Places?
