Fraction Foundations MOOC-Ed
Are you helping students learn fractions? Then help yourself to
the latest Massive Open Online Course for Educators (MOOC-Ed)
from the Friday Institute for Educational Innovation at North
Carolina State University's College of Education.
"Fraction Foundations" introduces activities about
fair-sharing, measurement, and the number line that you can use
to teach fractions concepts and skills. Goals of this free,
self-directed course include
developing a deeper understanding of the fractions
content standards, and relevant practice standards, that
apply in your school
investigating common student misconceptions about
fractions and why fractions are hard for children (and
adults) to understand
analyzing students' thinking about fractions to
addressing students' learning differences when teaching
fraction concepts and skills
This MOOC-Ed is organized around the recommendations of the
Institute of Education Sciences (IES) practice guide entitled
"Developing Effective Fractions Instruction for Kindergarten
through 8th Grade":
It follows on two previous Friday Institute courses: "Division
and Multiplication of Whole Numbers: Bridging to Fraction
Understanding" and "The Equipartitioning Learning Trajectory:
A K-5 Foundation for Rational Number Reasoning." The team from
North Carolina State University, last featured here in March,
offers these MOOC-Eds at no cost, thanks to funding support
provided by the William and Flora Hewlett Foundation, with
additional support provided by the Oak Foundation.
Registration will remain open until the end of the second week
of the course, which begins Monday, 22 September and closes
Tuesday, 16 December.
PoW taking place: math problem-solving moment of the week
"Knowing I was very close to my possible answer, I added 1
pound to Fifi and sub-tracked 1 pound to Sparky. I was very
confused at this moment because I had tried Fifi's weight as 9
pounds, 10 pounds, and 11 pounds, and I was very close. At this
point, I realized that the dogs can weigh a certain number of
pounds and a half. This helped me on my sixth and final
step.... My strategy shown on the picture below helped me
organize my estimations."

MATHCOUNTS Math Video Challenge
MATHCOUNTS has issued its annual invitation to teams of U.S.
sixth, seventh, or eighth graders: make a five minute-long
video that teaches the solution to — and demonstrates the
real-world application of — one of the 300 problems from the
2014-2015 MATHCOUNTS School Handbook.
Difficulty ratings and alignments to the Common Core State
Standards (CCSS) appear in the handbook's last three pages.

"Yes, only Module 1 has student materials; Mod 2 has teacher
materials, and Mod 3 is in 'Draft' form.... The Story of
Functions is very helpful for getting a feel for the topics.
Shameful that they are so behind schedule. Even so, I'm looking
forward to a good year. Good luck to everyone this
year — we'll get through it!"

The Feynman Lectures on Physics
One of the most popular physics books ever written went online
last week — and it features LaTeX equations rendered by
Originally published some fifty years ago, The Feynman Lectures
on Physics capture the talks given by Nobel Prize-winning
physicist Richard Feynman at the California Institute of
Technology. When Discover magazine selected it as one of the 25
greatest science books of all time, the periodical noted that
Feynman's "characteristic humor and peerless explanations
elevate these classroom lessons to enduring classics."
In The Feynman Lectures on Physics New Millennium Edition,
Caltech and The Feynman Lectures Website have updated and
posted a free-to-read online edition of the three volumes,
mechanics, radiation and heat
electromagnetism and matter
