Summer Math Photo Challenge


Calling all shutterbugs: there's a crowd-sourced math scavenger hunt afoot this summer!

Organized by percussive dance teaching artist and self-described "math explorer" Malke Rosenfeld, the #MTBOS Summer Math Photo Challenge 2015 will encourage the MathTwitterBlogosphere to focus its lenses in search of interesting examples of math ideas such as

  • arrays
  • composed and partitioned units
  • congruence
  • conic sections
  • equivalence
  • frieze patterns
  • reflections and rotations
  • tessellations and wallpaper groups

Sign up on this shared planning document to participate:


Rosenfeld has a book in the works with Heinemann that describes, analyzes, and illustrates the learning that happens at the intersection of math and dance in her Math in Your Feet program.

PoW taking place: math problem-solving moment of the week

"To get my answer, I used a few different methods. One method that worked well for me was comparing sizes. The other method was identifying the clues in the text. Some of the clues were...."

Math Illustrated


Days after appearing in these pages as the 2014 recipient of the Museum of Mathematics' Rosenthal Prize for Innovation in Math Teaching, Ralph Pantozzi launched his first blog.

"Do you see what I mean?" Thus begins the Kent Place School (New Jersey) teacher's debut post Sunday. Pantozzi goes on to articulate the aim of his blog as "illustrating" stories of learning math by describing his own and his students' experiences with learning particular topics and the different ways they "see" mathematical ideas.

Pantozzi has posted twice more since, on random walks. Stay tuned for

  • math tasks and questions
  • lessons
  • references to research with a focus on illustrating different ways that learners (teachers included) arrive at mathematical understandings and continue to grow into new ones

Now taking place: math education conversation of the day

"What a beautiful tribute to your mom, so close to Mother's Day 2015. Thank you for sharing her wonderful gifts with us."

Capturing Teachers' Usable Fraction Knowledge


Researchers from the University of Arizona have issued an invitation to all mathematics teachers currently teaching grades 3 through 6 to participate in an online research study.

The goal of the study: to understand how teachers' knowledge of teaching fractions relates to the Common Core State Standards (CCSS).

Selected participants will get to view and comment on short video clips of classroom instruction, then complete surveys. For their time (estimated at 2.5 hours total), teachers will receive a $75 gift certificate to Amazon.com.

Reach out to the researchers before month's end by downloading the PDF recruitment flyer above.
