BOB thoughts of the week that was just finished

I like polynomials.  I understand them better than the other units, and I find it easy to finish a vast majority of the work during class.  On a less positive note, I am concerned about the D.E.V project.  Coming up with problems that work that aren't too messy is a concern.  I'm also not sure how I'm going to get it online, I can't make a video because I don't know how to make videos, for example.  Mostly though, I am concerned as how to make the problems difficult enough.  If there was a diagram on the difficulty levels, I would find that helpful.  As it is, I don't really rank problems, I just try to do them.
