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 (new
in 2008!), visit the HW store at www.hwstore.org
for all your homework browsing needs.

Optional
Review Session, 9:00 a.m., Room LJ302. Invite your classmates from A period, F period, or any other
geometry section (including Ms. Dunn’s classes and Mr. Kelley’s class) to
join you if they wish. It would be helpful if you could work most of the review problems and check your
answers against the answer key
beforehand, but if you cannot, then please come anyway. See Thursday’s
calendar entry regarding bonus points (for my students only) for the review
problems. I will stay until lunch or until the last student has been helped.

5/30/09 
Mr. Hansen will be working at home, grading. If you
need emergency math help, please leave a message at 7035996624.

your choice. No other notes, calculators, electronic devices, or scratch
