Several weeks ago, a Senior Lecturer in the School of Education
at the University of Brighton (UK) put out a call for short
videos by math teachers showing how they approach teaching a
particular math concept, process, or disposition. On Tuesday,
the first batch of the resulting two minute-long "Mathagogy"
clips came out.
With more in the pipeline, these debut clips about math
pedagogy — often interspersed with segments from classrooms
and student "aha!" moments — outline approaches to teaching
sine and cosine graphs
with Cuisenaire rods
with one question lessons
Scroll down the mathagogy.com page to see which math teacher
"heroes" have already promised to produce a video next — or

PoW taking place: math problem-solving moment of the week
"It was different in the sense of topic and difficulty. But it
was manageable. It seemed like a problem where I did not have
to think much, but actually it was quite the opposite. I had to
really wrap my head around this problem to get it."
- Noah, highlighted in the Pre-Algebra PoW's latest solution
Looking for an online adaptive program to help you teach Pre
Algebra or Algebra 1? Pilot this self-described "digital
teacher's aide" for a year — free.
KnowRe provides granular, real-time assessments of students'
strengths and weaknesses in a setting that engages them with
an "open world" map of algebra concepts to encourage
comic strips that show a lesson's usefulness in
"walk me through" buttons
Modeled after the practices of "showing your work" and
reviewing every step to identify the gaps a student's
understanding, KnowRe creates a personalized math curriculum
that targets each individual's unique learning needs.
Awarded the Grand Prize in Google's Global K-Startup
competition last year, and Best Instructional App in the New
York City Schools GapApp Challenge last month, KnowRe invites
teachers to apply before the end of June for a free
Now taking place: math education conversation of the day
"Look at number 18 from a student's point of view. An argument
could be made that at (-4,0), the graph looks to be tangent to
the x axis and at x < -4, the graph appears to increase
slightly. That would disqualify the exponential choice and
make an argument for the quadratic. Again, we all understand
the answer is exponential but, look at it from the suspicious,
honor's kid point of view."

Learning Trajectories MOOC-Eds
The first of TurnOnCCMath's free, Massive Open Online Courses
for Educators (MOOC-Eds) mentioned in these pages a few weeks
ago has opened for registration.
"The Equipartitioning Learning Trajectory: A K-5 Foundation for
Rational Number Reasoning" will examine how
equipartitioning — grounded in fair sharing activities that
create equal-sized groups or parts — provides a foundation for
students' conceptual understanding of division, multiplication,
ratio, and fractions.
Open to anyone involved in mathematics instruction and
implementing the K-8 Common Core State Standards (CCSS) in
Mathematics, this free seven-week course runs from Monday,
1 July through Friday, 16 August:
The team from North Carolina State University that created
learning trajectories receives support from the National
Science Foundation (NSF), the Oak Foundation, and the Joseph D.
