Advanced Teacher Key Lessons 261-286
The Advanced Teacher Key is a teacher's companion to the Advanced Student Pages. While the Student Pages may be used and taught without this key, it helps the teacher by having all the answers marked on the page and providing some additional information.
If you are using the Unlabeled Wall Maps and Time Line along with the Student Pages, this key is required. It will tell the teacher when to place labels on the Wall Maps and Time Line and when to take them off.
