Does any rectangle have perimeter and area of the same
Can the plane be tiled with kites and chevrons?
In how many ways can 1/2 be written as a sum of unit fractions?
Come investigate these questions — and find out how they are
related — at the Park City Mathematics Institute (PCMI).
A program of the Institute for Advanced Study (IAS), PCMI has
just begun accepting applications for the 2014 Summer Session
of the IAS/PCMI Secondary School Teachers Program (SSTP).
Participating teachers receive full support and a stipend
during this residential program, which takes place in Park
City, Utah, from June 29 - July 19, 2014. Six quarter-credits
of 400-level mathematics are available from the University
Beyond the mathematical foci on fractions, tilings, and
geometry, SSTP participants will also consider research about
productive discussions and reflect upon how to facilitate them.

PoW taking place: math problem-solving moment of the week
"We had a lot of younger problem solvers this week, and the
submissions I've chosen to share reflect that. Nell L. and
Katie L.'s solutions are notable because each made a mistake
in their first submission. But after looking at the answer
that we provide, they found their mistake and revised their
solutions, doing some good thinking...."

NBA Math Hoops App
Calling all ballers and scholars: the NBA Math Hoops board game
has gone mobile!
Freely available for both iOS and Android phones and tablets,
NBA Math Hoops' app challenges students to build their own
teams out of the best National Basketball Association (NBA)
and Women's National Basketball Association (WNBA) players in
As a shot clock winds down, students do math in order to let
their personally drafted pro stars take shots based on those
NBA and WNBA players' real shooting percentages. Sink buckets,
and the app unlocks trophies. The NBA Math Hoops app also lets
students track their progress on national leaderboards, which
show how they stack up compared with the rest of the country's
First featured in these pages last June, NBA Math Hoops has
since posted test and survey data about their game's impact on
students, a map of US schools playing the game, and feedback
from teachers and students in their own voices:
Now taking place: math education conversation of the day
"There are contradictions in the newly released guidelines for
graphing calculators.... There are some other surprises in this
document: 'complete sentences should be used to support results
so that mathematical reasoning can be easily interpreted.'"

Snow Day Calculator
Wishing for more snow-bound time at home this holiday season?
Just enter your ZIP code into snowdaycalculator.com, along with
the number of school days you've already lost due to inclement
weather. The Snow Day Calculator analyzes this information in
light of the most recent weather data from Weather.gov to
predict the probability of an early dismissal, or no school,
for your next two days.
The manual version of the calculator lets you take into account
factors such as
school in mountainous area (yes or no)
leniency of administration (easy, okay, or harsh)
hype for a snowday (0, 1, 2, or 3)
Creator David Sukhin originally developed his predictive
calculator as a middle school student. He recently added a
feature that lets you join to receive predictions specific to
