Dan Anderson (@dandersod) (does anyone else just think of him in their head as "dandersod?") set a project for his calculus kids, live-tweeted it, and published their reports. You might have mixed emotions about the phrase "calculus projects," but I found these to be super fun, interesting, entertaining reading.#### Lani's Memo

This memo focuses on research-based ideas on how to support common planning time so that it has the greatest potential for teacher learning about ambitious mathematics teaching. To that end, we provide a framework for effective conversations about mathematics teaching and learning. We develop the framework by using vignettes that show examples of stronger and weaker teacher collaboration."Sometimes, you ask and the internet answers." Lani Horn came through with what Julie, and many teachers are looking for: nuts and bolts direction for teachers hungry for useful professional conversations. We're tired of wasting collaboration time and "PLC time" (a now-meaningless name if there ever was one) on aimless, unhelpful activities that don't have an impact on our practice, and we know there's a better way. This post is going to be a huge help. Bonus: a summary on research about using student performance data.

@k8nowak @TracyZager "In a class where math is taught in an authentic way, confusion is a good thing." Boom.

It will blow your doors off. Tracy is dazzling. Just go watch it. Best use of word clouds in history.

And that's a wrap! Somebody hold me accountable for doing this next Friday!

Mike's PBL is Project Based, but I think this fab collection of activities and recommendations for kicking off a school year would work just as nicely if your PBL is Problem Based.And that's a wrap! Somebody hold me accountable for doing this next Friday!
