I am doing some play adaptations to use with my French students and am wondering if you think it's fair to count worksheets and other supplementary materials in my page count. I am currently at about 20 pages of script (which I am editing down a little!) and 5 pages of activities. Can I count the activity pages?

That'd be nice! I've got about eleven thousand words of extra material, all of which I wrote in April (notes, character sheets, etc)!

Though, you should use whichever is the longest draft of script, regardless IMO!
