I’m done with my summer workshops, and I hope to resume blogging when the inspiration strikes. Today, a brief post about catchphrases, one per paragraph. (And no, this is not because this word has six consecutive consonants, which may well be a record.) I started thinking about this topic when I learned that Annie Fetter's catchphrase “What do… Continue reading Catchphrases

April Travels, May Webinar, Summer Workshops
I'll be traveling a lot this month. Here's the plan, should you want to say hello.New York City April 5, 4:30pm: I will present Geometric Puzzles at the Museum of Math Teachers’ Circle. Geometric puzzles are accessible to solvers of all ages, but they can also challenge even the most tenacious of solvers. Join math education author… Continue reading April Travels, May Webinar, Summer Workshops
Vocabulary
In my last post, I offered guidelines for sequencing math curriculum. The response I got on Twitter (and in one comment to the post) was quite positive. However, one point I made triggered some disagreement:Start with definitions? No! Most students find it difficult to understand a definition for something they have no experience with. It is more effective to start… Continue reading Vocabulary
Sequencing
In my last post, I argued that, as teachers and math education leaders in a school or district, we need to free ourselves from the sequencing preordained by the textbook, and instead pay attention to what actually works with our students. In this post, I will present some general guidelines for sequencing topics, and some… Continue reading Sequencing
Mind Maps
Alison Blank makes good points in her interesting presentation: "Math is not linear", where she encourages us to make connections, go on tangents, preview future topics and review past ones. In short, we should not be trapped in the inflexible sequence suggested by textbooks and school culture. In a recent blog post, Jim Tanton makes… Continue reading Mind Maps
Handling Wrong Answers
In my previous post, I listed questions to use in class discussions, or in conversation with a student or a group of students. Today, I'll discuss how to handle wrong answers. This is complicated and there is no single correct answer for all situations. I'll start by clarifying my goals:broad participation by students in the… Continue reading Handling Wrong Answers
Any Questions?
On the first weekend of December, the California Math Council held its annual meeting in Asilomar for the 60th time. (I attended for the 33rd time, and presented roughly the same talk I had presented in 1984.) Over the decades, the "must-attend" presenters have changed. Two of my favorites back in the day were Harold… Continue reading Any Questions?
Department as PLC
A PLC is a Professional Learning Community. In an ideal world, every math department is a PLC,but in reality there are some obstacles to that idea:not all schools give teachers time to dedicate to professional learningnot all teachers are interested in professional growthit is not clear what to do in a PLC, even if the… Continue reading Department as PLC
Geometric Puzzles at Asilomar
I'll be presenting a session on Geometric Puzzles at the Asilomar meeting of the California Math Council. (Saturday, Dec 2, Sanderling, 1:30pm The printed program says I'm in the middle school, but that is not correct. The app has the location right.). I will include material that I believe is relevant to teachers from kindergarten… Continue reading Geometric Puzzles at Asilomar
Puzzles for the Classroom
In my last post, I shared some generalities about puzzle creation. Today, I will zero in on the specifics of creating puzzles for the mathematics classroom. I will do this by way of analyzing some examples. Multiple PathsA characteristic of all classrooms is that they are constituted of students whose backgrounds and talents vary widely. … Continue reading Puzzles for the Classroom
