you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you
see PBC? Visit Mr. Hansen’s fabled abbreviations

Schedule
at a Glance (see archives for older entries) 


W 4/28/010 
MiniAP (graded, but not at
the same weight as a real test). 

Th 4/29/010 
Quadruple HW due (counts as
4 scores of 4 points each): 

F 4/30/010 
Double HW due: Set a timer
for 35 minutes. In your Barron’s book, turn to Practice Exam 3 (p. 419 in my
copy, but your page number may differ because of edition differences). Answer
problems #419 in ink on a clean
sheet of homework paper, without peeking at the answers. (If you run out of
time, stop immediately.) Work is optional. When you have answered all 16
questions, turn to the explanations (not the answer key, but the “Answers
Explained” section underneath) and see which ones you missed. 


As promised, here is the explanation of question #18. I
think I did a better job of explaining it than the Barron’s book authors did.
See what you think . . . 

M 5/3/010 
HW due: Same as last
Friday, except this time do problems #2040 from the same Practice Exam 3 in
your Barron’s book. As before, write a line or two of insight for each
question that you miss. I recommend setting a timer for 48 minutes before you
start. (Technically, the timing would be 47:15, but since it will take you a
half minute or so to get yourself positioned after starting the timer, you
can set the timer for 48 minutes.) 

T 5/4/010 
AP Examination, 1:00 p.m., Trapier Theater. Class today is optional for people who are taking
the exam. Everyone else needs to attend. Please confirm your exam status so
that I can take roll properly during C period today. 

W 5/5/010 
No additional HW due. 

Th 5/6/010 
HW due: If you have not
already done so, listen to this
radio segment about the placebo effect. There may be a short quiz. 

May 710 
More of the same. We may
embark upon a project. It is difficult to make much headway as a class during
AP weeks. 

T 5/11/010 
Class will meet in MH313
today. 

W 5/12/010 
No AP exams today. Wheee! 

Th 5/13/010 
Class today will meet in MH311. 

F 5/14/010 
NSA field trip for Form VI and a few other students will depart at 10:30 sharp from the Martin Gym area
and will return by lunchtime. The May 14 trip is a tour of the museum only.
The May 25 trip will include both a tour of the museum and a handson
codebreaking workshop conducted by an NSA mathematician, but unfortunately,
Form VI cannot go on May 25 because of the Snowpocalypseinduced rescheduling
of Career Day. 

M 5/17/010 
Please come to JBAM Monday
morning at 7:30. Full details and rules are at jbam.net.
I hope to see everyone there! 

T 5/18/010 
Please come to McDonald’s
Week, day 2 (Big Trig competition). 

W 5/19/010 
Senior skip day (no class). 

Th 5/20/010 
Please come to Big Trig Classic at McDonald’s in the early
morning. 

F 5/21/010 
Class today meets again in MH313. 

M 5/24/010 
In class: Who will be the
anchorman? Alas, this question is not to be settled today. 

T 5/25/010 
Career Day (no class). 

W 5/26/010 


Th 5/27/010 


F 5/28/010 
Last day of class; end of
fourth quarter. All assignments and extra credit, if any, must be submitted
by 3:30 p.m. today. 

M 6/7/010 
Final Exam, 8:00 a.m., MH102. I am hoping that everyone will be exempt from this
requirement. However, it remains to be seen.
