Math Ed SaidJune 24: Everyone was talking about Brexit, including math teachers. They shared the Washington Post story, "The British are frantically Googling what the E.U. is, hours after voting to leave it," highlighting some of the post-vote confusion and uncertainty.

June 27: While a number of people were already talking about Tau Day (see June 28th below), Sara VanDerWerf's post, "Secondary Number Talks (I’ll convince you with ducks)" was popular on the 27th. High school teachers are prone to complain about the lack of arithmetic fluency, and Sara suggests we re-evaluate our claims of not having enough time to build that fluency with some strategically placed number talks.

June 30: "The Problem with Story Problems" by Anita Bright in Rethinking Schools is likely to challenge you with its examples of bias, privilege, normativity we typically see in math word problems. It's easy for me to read something like this and think, "Okay, yes, I agree, go on...now really, you're taking issue with wallpaper?" I have to remind myself that this article isn't about the wallpaper or any other particular example, and I'd be foolish to be derailed by such a detail. Focus on the bigger picture: the worldly contexts in which we mathematize are part of the student experience, and context deserves our scrutiny because it reflects our assumptions and values.
