We work off of older Nystrom Desk Atlases.  The students need to have one of my specific Atlas books in order to complete their work.  I currently only have 29 books, and therefore do not let students take them out of the building.  I do have and extra old version that is almost similar that students can take home, but they will need to double check dated materials.  Students set their own goals as to how many atlases they can complete in a quarter.  They work at their own pace.  They correct their own work.  They make corrections to every question they get wrong.  I have found that this system places students in charge of their own learning.
