New Samples of PoWs
http://mathforum.org/pow/teacher/samples.html
Want a challenging open-response math problem — and solutions
to it that students have written, with explanations, in their
own words?
Freely download a Primary Problem of the Week (K-2), Math
Fundamentals PoW (3-5), Pre-Algebra PoW (6-8), Algebra PoW, or
Geometry PoW. Accompanying sample support materials include
-
Teacher Packets, for the "answer check," a range of
solutions written by the Math Forum, tips about how to
introduce the problem to students, and ideas about how to
move students forward
-
Scoring Rubrics, for assessing your students' solutions
with our six-category scoring grid
-
Scenarios, for a version of the problem set-up without the
question — a good way to introduce the PoWs in your
classroom and have students focus on the story of
the problem
The Problems of the Week Library now has over 1,800 past PoWs,
more than 300 of which feature support materials — all
available with a class account:

Earthquakes for Kids
http://earthquake.usgs.gov/learn/kids/
The U.S. Geological Survey (USGS) offers puzzles, games,
learning links and activities, science fair project ideas,
animations, and an explanation of the science of earthquakes.
In particular, read a primer on earthquake magnitudes, which
explains the logarithmic nature of the Richter scale:

Click the wide blue button to launch the "How Much
Bigger ..." calculator:
http://earthquake.usgs.gov/learn/topics/calculator.php
The USGS offers more educational resources on earthquakes here:
http://earthquake.usgs.gov/learn/classroom.php
For years, the USGS has collected data from individuals about
the effects of the earthquakes they have felt — or not felt.
Now done online, this crowd-sourcing helps researchers create
instant Community Internet Intensity Maps (CIIMs) of shaking
intensities and damage, sometimes providing data in areas that
lack seismic instruments.
Share your experiences, in English or Spanish:

"One of my major teaching goals this year is to shift my Stats
class to a project-based learning approach. The first unit is
'Exploring and Understanding Data,' and the project which
guides the unit is 'How should Dave compute your grade in this
class?' The article on median grading will be an incredibly
useful addition to the students' resources, so many thanks to
Steve for posting the link."

Wolfram|Alpha in the K-12 Classroom: Contest and Free Seminars
http://blog.wolframalpha.com/2011/08/22/
wolframalpha-goes-back-to-school-for-teachers/#more-14906
The makers of Mathematica want to hear from K-12 teachers who
use Wolfram|Alpha in class -- and they're giving away more than
a penny for your thoughts!
Reply to this recent blog post about how the W|A computational
knowledge engine has positively impacted your teaching or your
students' learning, and your comment of fewer than 100 words
enters you for a chance to win your choice of Course Assistant
apps for your entire classroom.
Wolfram has already rolled out coursework guides for
pre-algebra, algebra, pre-calculus, calculus, and statistics.
Check out the full slate of W|A apps for the iPhone, iPod
touch, and iPad:
http://products.wolframalpha.com/courseassistants/
For complete rules of this giveaway, see
http://www.wolframalpha.com/educators/teachersappcontest/terms.html
Hurry: the contest closes next Tuesday, 30 August.
Wolfram will then start offering free online seminars that
provide an introduction and overview of how to leverage W|A for
the K-12 classroom:
