Powerful Problem Solving: It's Here!
Max's book has officially hit the shelves!
Powerful Problem Solving: Activities for Sense-Making with the
Mathematical Practices gathers what we've learned about helping
students become proficient problem solvers, focused through the
lens of the Common Core State Standards (CCSS) for
With the book's publication, we unveiled an accompanying website
yesterday, as well. Whether you've purchased the book or not,
watch our free YouTube clips of Max and the rest of the Forum
team as we teach at a school near us here in Philadelphia,
using Problems of the Week (PoWs) and the many activities from
Powerful Problem Solving:
PoW taking place: math problem-solving moment of the week
"I liked getting to read so many 'thinking stories.' I got to
read about your first ideas and how they changed as you tried
different things. I got to read about different strategies...."
- Max, commenting on the Algebra PoW's Latest Solution
Desmos just came out with a way to learn about functions: by
drawing funny faces.
Having recently teamed up with Dan Meyer on their first
collaboration, the folks behind the desmos.com free online
graphing calculator realized that making thoughtful content "is
really freaking difficult ... and really freaking fun."
Des-man, the Work In Progress that Desmos announced Wednesday,
guides students through the process of making domain and
range restrictions. Then — "navigating the fine line between
doing too much and not enough, between guiding and
pushing" — Des-man prompts students to "draw" a face
A teacher dashboard that updates in real time lets you monitor
your students' progress as they plot functions. Des-man's
filters narrow in on just those students who, for example,
have experimented with circles or ellipses.
Desmos welcomes feedback on this Work In Progress, which draws
on an idea blogged by longtime PoW member Fawn Nguyen. From
"where it shines" to "where it falls short," Desmos wants to
know; and further seeks your suggestions for another lesson, or
what you want to see more from them:
Now taking place: math education conversation of the day
"I have videos of my lessons and other help videos with
individual questions. The downside to the site is that I have
to go off 'script' quite often. The upside is that my students
have a little more control over pace."

Equipartitioning Learning Trajectory MOOC-Ed
A Massive Open Online Course for Educators (MOOC-Ed) kicks off
two Mondays from now. It's based on fair sharing — and
With units such as "Deal or No Deal?" and "Let Them Share
Cake!" and "That's Not Fair! (Or Is It?)," the MOOC-Ed focuses
on splitting, re-allocating, and other ways to form equal-sized
groups (from collections) or parts (from a single whole). Such
fair sharing, or "equipartitioning," establishes a foundation
for students' conceptual understanding of division,
multiplication, fraction, and ratio. A team led by Drs. Jere
Confrey and Alan Maloney will provide instructions, suggest
resources, contribute to discussions, and answer questions
from course participants in each lesson of the course.
Recommended for elementary and middle grades educators and
"open to anyone interested and involved in mathematics
education," the Equipartitioning Learning Trajectory MOOC-Ed
officially opens Monday, 7 October, but continues to accept
registrations until the end of its first week. Get the scoop on
time commitment, certificates of completion for Continuing
Education Units (CEU), and other frequently asked questions
Learning Trajectories and its TurnOnCCMath.net site first
appeared in these pages this summer. Created by a research
group from North Carolina State University, this MOOC-Ed from
Generating Increased Science and Math Opportunities (GISMO) is
offered by the Friday Institute for Educational Innovation, and
made possible in part by funding from the National Science
Foundation (NSF) and the Oak Foundation.
