Quality over quantity this last month. Still, I could use a little more quantity. Let us know your new subscriptions and follows in the comments.

New Blog Subscriptions

• John Mason is one of my favorite writers on math education and should be yours also. His RSS feed has exactly one post on it (on creating a “conjecturing atmosphere”) but that’s the great part about RSS. One day he’ll write a second post, I’m sure much later than any of us would like, and you won’t have had to check his website. It’ll just be there.
• Caitlyn Gironda wrote a very thoughtful post about our Polygraph lesson.
• If you were enjoying Chris Hill’s blog on innovative physics instruction, joke’s on you because he moved it. Right here.
• Khan Academy’s Lab School’s blog is written by students and employees. (Related: this cringey Wired profile.)

New Twitter Follows
