Even though this bookmark has nothing to do with Adding and Subtracting Rational Expressions (as it advertises to do so), I do think that it was wonderfully designed. I just wish that I could find my printed copy. The student printed it on heavy card stock and even hole-punched it at the top and strung a piece of yarn through the hole for a really professional touch. However, I think had a couple of officemates from my past steal them. Man oh man.
