I posted an overview, on NotGrass' Exploring World History, in the beginning of October. I am very happy with this curriculum, but I have not been able to find gradebooks anywhere online! The NotGrass website has a supplement page for the course, but it is only for the 2014 edition. This supplement page includes a gradebook, but it differs from my 2008 version. So I created my own!
Here is my grade-book for NotGrass' Exploring World History 2008 Edition. Each tab at the bottom contains a quarter. Quizzes are worth 10 points, because they have 10 questions. Exams have 50 questions so they are counted as 50 points, and I counted writing assignments as participation grades of 5 points. You can make any changes you like, and save it as a PDF to print it. Or simply leave it as is, and the spreadsheet will automatically count up your grades as you add them in. You final grade will be shown at the bottom of the column "Score."
