19 Exemplar CCSS-M Resources


After sifting through nearly 400 websites, researchers from the American Institutes for Research (AIR) and Education Development Center (EDC) have highlighted thirteen of the best collections of math lessons, units, and assessments for the Common Core State Standards (CCSS).

"Quality Online Resources and Supports for Educators Teaching the CCSS," which came out late last week, shines a light on another six sites for their value in supporting math teachers' understanding of the CCSS.

AIR and EDC selected these great, free online resources — most of which have also appeared in this newsletter — by placing a special emphasis on explicitness, coherence, and easy navigation of the CCSS structure.

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

"What made this fun was that there turned out to be so many different ways of solving it. There are at least six different approaches, all of which are excellent, and most of which I didn't think of. Some of them make the problem a lot easier than I thought, especially...."
- Annie, commenting on the Geometry PoW's Latest Solution

Teaching the Core Video Library


So, what does a lesson aligned to the CCSS look like? What does it sound like in actual practice?

A new video library launched Tuesday with free examples of strong, bell-to-bell lessons videotaped in real schools:


Starring teachers hand-selected by their districts for classroom excellence, each clip in the Teaching the Core Video Library comes with descriptive annotations from educators that call out

  • teacher actions
  • student behaviors
  • lesson elements that support CCSS learning

Every video from Teaching the Core also includes the materials used in the lesson, examples of student work, and short teacher interviews about the lesson.

A project of the non-profit Student Achievement Partners, Teaching the Core Video Library received support from the Danielson Group and funding from The Leona M. and Harry B. Helmsley Charitable Trust.

Now taking place: math education conversation of the day

"I am concerned that the lack of a flappy or angry bird hook may make it a bit dull. Please advise."

A Critique of a CCSS-M Test


Millions of students in 17 states will take a CCSS-M test over the coming weeks. One math education veteran has reviewed some of the questions they will face — and has deemed them "fatally flawed."

Analyzing ten questions across four different grades from practice and training tests, Key Curriculum Press co-founder and publisher Steven Rasmussen picks apart the assessment's wording, graphical representations, user interface, and more. He then warns that the results of this testing will confuse the national debate about the CCSS; asks "What Can We Do?" — and offers several answers.

Rasmussen has served as principal investigator on six National Science Foundation (NSF) projects. To read his full report — complete with footnotes and a discussion of one tenth grade question from the perspective of calculus — download this free PDF:
