January was a busy month on the blog. Here’s a recap of the lessons, posts, and other math-related things that filled up those 31 days.
- Match My Line. The start of this recent “Match My Graph” madness.
- Match My Parabola. If the reaction on Twitter is any indication, hands down the most popular lesson I’ve posted.
- 5 Things Every Teacher Should Know About Twitter. A quick introduction to using Twitter. By no means comprehensive, but a nice start for those interested in expanding their online PLC.
- Two Wrongs and a Right. An error-analysis routine inspired by Michael Pershan’s work at mathmistakes.org.
- Age-Appropriate? Not Exactly. Valuable? Absolutely. A linear graphing challenge experiment gone… What’s the opposite of “awry”?
- Twitter Chats vs Family Dinners: Do We Really Have to Choose? I love Twitter. And Twitter chats. But family life means I usually choose not to participate. Enter #slowmathchat, a weekly chat not tied to a particular time of day.
- Four Points, One Line. A work-in-progress linear graphing challenge for students, with a goal of eliciting a variety of equation forms.
