Here are 8 circle theorems, written by a Brit so you'll have to "translate" to American English ...
Are these the most important ones?
Are there any that are missing that you feel should be included in this group?

Here are some questions (to teach precalc & stats):
What's a logarithm?
What's a situation in which mean & median are different & one might be preferable?
How do you see math & social justice combining?
What's your fave math thing?
Then: minilesson on what Ss are learning. I think a minilesson is good & especially if it's on the material they'd be broaching. More interested in familiarity with content & pedagogical moves than a pre-polished lesson.
I also asked about math/gender since I teach at a girls school.
Views/whys on tracking also good.

1) What is math?
2) What's an interesting math problem you've recently solved?
3) How can you tell if the structure (rather than content) of a lesson you've taught was effective?

From our recent group True-False quiz:
Two of these had correct response rates of 90%, the other two 60%. Which are which?

What's your take here? Does it matter if the tape diagram attempts to represent the size of the relationships? Does it matter if it's the student's or the teacher's model?
I Personally think that diagrams should be fairly true, or be labelled as "Not to Scale" with explicit instructions to consider re-drawing the diagram in any such case.

What do you think of this suggestion?
Should we stick to Algebra 1, Geometry, Algebra 2, Pre-Calculus, and keep calling things Remedial, College Prep, Honors?
"This gets us started on another large conversation. In my dream there would be three ways that students could take math in high school.
1. Math for future scientists and engineers.
2. Math for daily life.
3. Math for fun, beauty, and intellectual appreciation."

Periodically, the conversation turns to Calculus.
"Why is Calculus the goal, the high point, of every HS math sequence for every student?"

In the 1960's and 1970's, the United States was trying to "catch up" to Russian education standards. Every student was told that in order to graduate, they had to take (and pass) Algebra 1, Geometry, and Algebra 2?
Does that make sense?
I maintain that Statistical Reasoning should be part of that minimum, and that Algebra 2 does not have to be?

What do you think of this method?
"I write a lot of technical and narrative documents at work, most 2 to 6 pages. I wanted to share an editing technique that a past mentor taught me that I think is useful and under-valued for these kinds of documents: counting.~Marc Brooker
Start off with a list of key points you want the document to communicate. In two pages, this probably should be between one and three. In six pages, maybe you can pull off four. In a twelve page research paper, maybe a couple more, but that's it.
Then rank your points in order of how important it is that the audience understand them. Think about how complex, controversial, or unfamiliar each point is. Look at this from the reader's perspective, not yours.
Next, go through your document sentence by sentence and count the words you dedicate to each point. Compare the two lists. Are you spending your word budget in approximate order of importance? Does it reflect the order of complexity?
If it's far off, and you've spent a lot of words saying something unimportant or easy to understand, then you've got a great place to start editing. If you've spent space on things that aren't your core points, that's an even better editing opportunity.
Next, look at the order of how you spend time on each point. Does that order reflect the order of importance? Does it tell a story that either leads with, or leads to, your most important points?
"Extracting the outline" in this way, you get to step back from your own writing, and make sure you haven't lost your core points in a sea of details. It's not the last word in editing, but I do it every time I write an important document I really need the audience to understand."
