I've been out with a sick kiddo this week, and I hate just leaving boring old worksheets for my students to do with the sub, so I was excited when I saw this in my Twitter feed yesterday! I retyped it to give some specific instructions to my students and to add a few Calculus specific vocabulary words to the list. I talked with my sub (a former teacher and assistant principal who retired but still comes back to sub) and he felt comfortable letting the kids get a little creative today. I can't wait to see what they come up with! It'll be so much more fun to "grade" these when I get back than it would have been to have a worksheet waiting for me.
