June 18: Mike Lawler showed us "A fun way to estimate e with kids." I don't find much of anything with e and natural logs to feel natural at all, so I watched all three videos with interest.

June 19: A nice thing about writing versus talking is that when I want to salute the U.K. for something good, I can just use a word or phrase without attempting the accent. Here's Hannah Fry with a cracking interview in The Guardian, "There's a mathematical angle to almost anything."

June 20: In the latest installment of the story that just won't quit, Rebecca Mead in The New Yorker writes, "Andrew Hacker, an outspoken critic of mandatory algebra education, is asked to defend his contentions at the National Museum of Mathematics."

June 21: A Katrina Schwartz article from last August made the rounds again, featuring comments from David Wees in "Seeing Struggling Math Learners as 'Sense Makers,' Not 'Mistake Makers'."

June 22: With clever (and bad) drawings, Ben Orlin illustrates Sfard's process/object divide with "What Students See When They Look at Algebra."

June 23: An interesting outcome of the Fordham survey described in Education Week is that, on average, teachers seem to say some things that might seem contradictory. Here, they say there is a higher priority on computation, yet memorization is down. Similarly, when Choppin, Davis, Drake, and McDuffie (2013) surveyed middle school math teachers about Common Core, in which some teachers said Common Core requires them to teach more conceptually and more procedurally. Results like these are a good reminder that survey responses sometimes have to be taken with a grain of salt.

Around the Math Ed WebYou can check out the recording of Sara Van Der Werf's Global Math Department presentation, "The Pursuit of 100% Engagement: Practical ideas to get you closer." It doesn't appear there was a new presentation tonight, and I don't see one for next week, yet, but you can check the GMD website to see when the next one is announced.
Otherwise, the math ed web seems pretty quiet. I think either teachers are taking a well-earned break, or they're too busy at conferences or in PD to be doing as much online.
