College Entrance Exam Math Prep
Know a high school junior taking the SAT or ACT in the coming
month? Need a free, interactive library of the most complex
math problem types found on those college entrance exams? Then
check out the College Entrance Exam Math Prep site.
Click the blue "Application" tab and "Start SATACT EduCAD"
button for a math problem typical of those standardized tests.
A timer will start counting down from ten minutes. The "show
next step" button provides a hint about the strategy to take;
keying in a correct answer triggers a similar but more
difficult new question.
We first learned about the freshly-launched
collegeentrancetestprep.com through e-mail last week from one
of its creators, who also developed the popular Flash Cards for
Kids site — first featured in these pages sixteen years ago!
PoW taking place: math problem-solving moment of the week
"The first thing I did was draw a diagram representing the two
planes, their path, and the amount of altitude gained by each
one, in the form of right triangles. The hypotenuses of the
right triangles is the path of each plane and the speed, the
base of the triangle is the ground, and the height of the
triangle is the altitude gained by each plane. I pretended
each plane flow for 1 hour...."

Math with Bad Drawings
A high school teacher began blogging last month "about the
things I like [and] also about the things I can't do." By
juxtaposing the two and "owning up to weakness and drawing
strength from successes," Ben Orlin hopes to "capture the
contradictory state of the teacher, of the mathematician."
Orlin's posts from Oakland, California — illustrated with
dry-erase marker art that he says his fiancee "charitably"
rates as average for a sixth grader — already include

Now taking place: math education conversation of the day
"So is it a matter of right or wrong? I'm not sure.... It
seems to me Common Core analysis type questions are the
perfect place to have this discussion with a geometry class.
In theory, all students should be able to reason and think in
this manner (and certainly may have been, had the Common Core
been allowed to be phased in from kindergarten on up). In
reality, I certainly realize that many, many students are not
ready for this kind of thinking — but this kind of thinking
and discussion is exactly what geometry education needs."

Curious to hear the voices of other mathematics teachers from
around the US as they process their practice? Then listen in on
this secondary math education podcast.
Since March, Ashli Black has conducted in-depth interviews with
Daniel Schneider, aka "Mathy McMatherson"
Tina Cardone, blogger of Drawing on Math
Avery Pickford, who tweets @woutgeo
Before joining the Illustrative Mathematics project as its
Director of Social Networking, Black taught for six years in
Edmonds (Washington), where she earned the Outstanding Educator
Award from the Mountlake Terrace High School PTSA. Catch her
"edu-nerd-speaking" with the fellow alumni of the Park City
Mathematics Institute (PCMI) listed above before posing them
questions such as
When did you know you were a teacher?
Are you you when you teach?
If you could give one gift to the teaching community, what
would it be?
What question do you have for the community at large?
