SUMMER PROBLEMS OF THE WEEK
http://mathforum.org/pows/
Every two weeks from June through August, the Math Forum will
continue to post challenging, non-routine problems and accept
solutions to them. Although we will have only a few volunteers
doing mentoring -- and our responses will otherwise be scaled
back as we get ready for a new series of problems at the end
of August -- we encourage all Problem of the Week members to
continue using the PoWs throughout the summer.
Over the course of the recently concluded 2011-2012 academic
year, we posted a total of 100 Current Problems of the Week,
each with its own supporting resources -- a great starting
point for designing your own summer projects. For those with
Full PoW memberships, or access through your schools or
districts, help yourselves to the Library Problems. For
starters, we've highlighted a seasonal selection in these
pages before:

PoW taking place: math problem-solving moment of the week
"This problem was a difficult one to explain and show your work
on. One key was drawing a good picture to help you understand
how all of the lengths and widths were related to one another.
Cynthia, Richard, and Matthew shared this picture, which helped
me understand the meaning of the different expressions they
used in solving the problem ..."

SUMMER FERMI MATH LEAGUE
http://district287.org/fermi/
Do you like to measure, estimate, and play around with
technology? Then join the Fermi Off-the-Wall Math League!
This Internet-based math competition welcomes students in
grades 1-9 from around the world who seek enrichment, small
group work, and creative, technology-rich experiences.
A Fermi question is posed with limited information given.
For example,
- How many water balloons would it take to fill
grandma's bathtub?
- How many cockroaches will fill the trunk of a VW Beetle?
- How much fabric would it take to make a camo-suit for
Moby Dick?
- How many eggs would fit in the Trojan Horse's body?
Fermi questions require that students ask many more questions;
emphasize process rather than "the" answer; demand
communication and writing; and utilize estimation, rounding
numbers and guesses.
The four-week Summer '12 season starts Tuesday, July 12th.

Now taking place: math education conversation of the hour
"The thing that bothers me about systems like this is that it
seems to give legitimacy to the totally arbitrary scale that
says '90% is an A.' We all know that 90 means 'bottom of the A
range' and 70 means 'bottom of the C range.' But why? What is
so magical about those cutoffs? They are completely arbitrary.
I would much rather look at the quality of work on the test
and make grade decisions based on that."

STATISTICS WORKSHOPS FOR K-12 TEACHERS
http://www.amstat.org/education/workshops.cfm
The American Statistical Association (ASA) offers two workshops
in conjunction with the 2012 Joint Statistical Meetings,
July 28 - August 2, San Diego, California.
The Meeting Within a Meeting (MWM) Statistics Workshop for
middle and high school mathematics teachers seeks to enhance
understanding and teaching of statistics within the mathematics
curriculum through conceptual understanding, active learning,
real-world data applications, and appropriate technology.
http://www.amstat.org/education/mwm
The Beyond AP Statistics (BAPS) Workshop, for experienced
Advanced Placement statistics teachers, consists of a day of
enrichment material just beyond the basic AP syllabus.
