you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you

Schedule
at a Glance (see archives for older entries) |
|
|
|
W 4/28/010 |
Mini-AP (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 #4-19 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 #20-40 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 7-10 |
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 MH-313
today. |
|
|
W 5/12/010 |
No AP exams today. Wheee! |
|
|
Th 5/13/010 |
Class today will meet in MH-311. |
|
|
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 hands-on
codebreaking workshop conducted by an NSA mathematician, but unfortunately,
Form VI cannot go on May 25 because of the Snowpocalypse-induced 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 MH-313. |
|
|
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., MH-102. I am hoping that everyone will be exempt from this
requirement. However, it remains to be seen. |
