I have graded only 1 out of 4 classes worth of midterms... can't put them off too much longer. That period averaged a 61%. I was hoping it would be higher, but given the nature of the cumulative exams, I guess that is pretty good. It really helped identify the kids that have no idea what is going on, or are not retaining anything, in a way that the skills tests don't.

Tomorrow, we move on to unit 3, which is on functions. The first lesson is on the various representations of relations (table, arrow map, graph, equation, set of ordered pairs), what domain and range is, and how to determine if a relation is a function. I put together a Keynote that I think is pretty good, though it took way too long to build. I hope it is useful to someone besides me.
