Crafty, Maybe, But Not Craftsy

I am working on kitchen curtains, but I've been hired on as a tutor at ITT-Tech, and it's the end of the quarter. My biggest project lately was making a review sheet for the students.  We had a big review session on Saturday--3 hours long.  5 students showed up at various times, out of the 20 or so enrolled.

 So, my pictures today are of math review!

If anyone wants all seven pages, please post a comment. These are just random selections.  I could probably improve them.  I think I'll run them by my math whiz son.
