A New York City math teacher has begun blogging in an effort
"to better understand the connections between problem solving,
learning, and teaching."
Michael Pershan launched "Problem Problems" last month with
three related questions in mind:
How does a teacher help a student learn math through working
on math problems?
How can I get better at helping my students learn math from
working on math problems?
How do I get better at this aspect of practice?
To date, his posts have included
Getting Stuck on a Geometry Problem
Minimalistic Hints Are Still Hints (Or: If You're
Helping, You're Doing the Work)
The First Time I Thought about Problems on Twitter
Structure of Solving Visual Pattern Problems, II
Direct Instruction of Problem Solving
Completely Stuck, Looking at a Solution
Thinking You Might See with the "Worm" Pattern
How Theory Could Help Me Teach Visual Patterns
Pershan has appeared in these pages several times before,
starting with his mathmistakes.org site, where he still posts
photos of math errors made by students — and invites other
teachers to come analyze and discuss the misunderstandings
behind those mistakes.
Google Spreadsheets, Improved
Google has rolled out several slick data analysis and graphing
features to its free online spreadsheet software.
With Monday's update, Google Sheets now lets you
filter rows and columns by conditions such as "greater

label bars and points with their exact values
embellish the data points of line or scatter charts as
stars, triangles, pentagons, and other shapes
