Are you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you see PBC? Visit Mr. Hansen’s fabled abbreviations page to make sense of those cryptic markings you see on your papers. Also, visit the HW store at www.hwstore.org for all your homework browsing needs.

Schedule at a Glance (see archives for older entries) Written assignments should follow the HW guidelines. See the HW store at hwstore.org for more examples.
F 5/28/010	Last day of class; end of fourth quarter. All extra credit puzzles must be submitted by 3:30 p.m. today. In class: Review for final exam. I also meant to distribute the Chapter 14 Big Quiz, but unfortunately I forgot. If you have not received your graded paper from me, it has been e-mailed to you. Hard copies can be picked up during Tuesday’s optional review session. The class mean and median were both above 47.5 points out of 60 (79%), which is somewhat higher than usual.

You do not need to stay for the full time; you can drift in and out as you wish.
