We have mentor groups from Missouri and Pennsylvania giving
students feedback on three of the next four Math Fundamentals
Problems of the Week — starting with "A Million in Time," now
in preview, through the FunPoW that opens Monday, 31 March.
Please have your students submit solutions; and if they receive
replies from a mentor, encourage them to revise. Not only will
your students learn more, but the mentors will learn, as well!
Want to get in on the fun, but don't have a membership?
Register a trial account, which lets you submit to the Current
PoWs. This free 21-day demo also gives you access to a sample
of the Problems of the Week Library and Write Math alignments
to the Common Core State Standards (CCSS):
PoW taking place: math problem-solving moment of the week
"Neither of these students included solutions to the Extra,
but you might want to give it a try after reading Ava's
explanation. Ava also struggled with the fact that there
aren't any numbers. As a result of overcoming that obstacle,
she gave this hint at the end of her explanation: 'My advice
would be to not get hung up, and to not be afraid to charge
into the unknown with variables.'"

Unsolved K-12 Problems
A conference to "find gems that belong in every child's
experience of math" has yielded a YouTube playlist of unsolved
math problems for grades K-12.
In the introductory video, conference co-organizer Gord
Hamilton explains how open questions remove the stigma of
failure and engage a full spectrum of student ability. They
also belong in the math classroom much as Mt. Everest deserves
climbing: "because it's there!"
The remaining fourteen videos introduce one unsolved problem
for each grade K-12, plus a collection of "discards" previously
under consideration for kindergarten. Enlivened by simple
computer animations and already incorporating feedback from
teachers who have used them in their classes, most of the clips
play in under five minutes. Fifty seconds into this one,
Hamilton lists "fun" and "worthy of mathematicians" among the
conference's eight selection criteria for problems:
First mentioned in these pages last year for his MathPickle.com
website, Hamilton concludes "there's still a lot of room for
you to help" — particularly for grades 6, 7, 8, and 12, as
well as in developing stories that would further engage
students. Just enter comments in the "share your thoughts"
boxes below his YouTube videos.
Now taking place: math education conversation of the day
"This is a very thorny problem and I appreciate the help that
people have offered. What I was trying to do was to use the
math to make sense of the physics.... I just wanted input
because various Internet searches didn't yield anything."

Summer Workshops for Math Teachers
The Center for Innovative Teaching (CIT) has announced its
summer weekend workshops — some, given by an educator who
participated in the conference on unsolved problems, above!
Taking place at the Urban School of San Francisco, CIT's math
- Hands-On Geometry: kinesthetic, hands-on
- Transformational Geometry: rethinking geometry from a
- Advanced GeoGebra: sliders, hide-show buttons, animation,
- No Limits: a concrete introduction to the main functions,
geometry of parabolas, dynamical systems
A limited number of public school teachers will receive a 90%
discount on their registration fees.
CIT has also extended readers of the Math Forum Internet News a
5% discount for any summer workshop; just use the
