Well, I am currently working on SOTW 1, level PY (picture books for young learners), I would say it is K-2. I have 2 more levels and a less intense (and less chronological version, based on A Little History of the World) planned. Then I have Cultures and Creatures Geography with 3 levels planned as well. I have 9 weeks completely finished. I was trying to schedule it out without completing the notebook pages and it has just blocked me, so bacxk to completing the notebook pages!
