Twitter Math Camp 2013

This past Sunday, TwitterMathCamp 2013 (TMC13) wrapped up on the campus of Drexel University — the Math Forum's home! If you missed all the fun that we hosted, start with the wiki above for

  • morning sessions
  • presentations, afternoon sessions, and "My Favorites"
  • project ideas ("things that might be cool to make, build, create or organize")
  • participant Twitter list

Among the participant blogs also listed on the wiki, check out this reflection about new best friends made, shout-outs, and "superlative awards" — illustrated with a running man zebra and an origami fractal dragon — all inspired "because TMC13 is totally worth me stretching outside my comfort zone":

The last day alone of this self-styled "guerrilla professional development for math teachers" inspired 1,500 tweets, and generated more than two million impressions. One math education professor has since tweeted about the recent blog post of a participating math and physics teacher, who wrote, "OK, I'm three days out of Twitter Math Camp and my brain is so chock-full of great things I want to implement in my class this year, I need to write them down...."

Get in on the continuing action with the hashtag #tmc13:

Now taking place: math education conversation of the day

Mathlets for Teaching Elementary Mathematics

http://www.commoncoremathlets.com/

Dave Posner recently launched a website of visual models intended to seed elementary students' "pre-endowed imaginations with images tailored to evoke patterns that are the basis of the elementary mathematics curriculum." The "mathlets" already available touch on the Common Core State Standards (CCSS) category of Numbers and Operations in Base Ten for grades K through 3:

  • base ten counting
  • base ten adding
  • laws of addition
  • train track addition

Posner welcomes comments for improving existing mathlets, suggestions for new ones, and bug reports that detail browser and computing platform specifications.

He let us know about commoncoremathlets.com by suggesting it to the Internet Math Library, which today boasts some 11,000 math and math education websites. Share your own by visiting

"Isn't it interesting that we had to call the state on the fact that bivariate can be for categorical data — and then as I look at the second module for Algebra, one of the lessons is titled 'Summarizing Bivariate Categorical Data.'"

Almost a Third Grader

http://www.almostathirdgrader.com/

Every weekday since their school year ended, a group of second grade teachers in Minnesota has posted an original video lesson to help rising third graders review what they learned last year, and introduce them to the content of the coming autumn. Links to selected quizzes and resources appear under "review and challenge."

Check the lesson schedule for almost-third-grade math topics, which already include

  • comparing & ordering numbers
  • multiple digit subtraction
  • fractions
  • capacity
  • length measurement
  • multiple digit addition

For a more visual overview of the short clips — some narrated by or starring children, many with prompts to "press pause to stop and think" — visit their Pinterest pinboard:
