@CmonMattTHINK I struggle with the focus on formal two column proof...it has disappeared from a lot of what I do in geometry. I've found myself substituting the spirit of it with claim and evidence. This turns most of the proofs into shorter answers with work to support or statements w/reason.

I’m still sad about Geometry teachers wishing they could cut proofs from the curriculum. I mean, I get it. But how badly must we have effed up math education when learning how to effectively use deductive reasoning is so universally reviled?

@Desmos Added some slice shading: desmos.com/calculator/1kk… #iteachmath #mtbos

I wanted something to help animate polar graphing, showing Θ and how r can be same direction (+) or opp. direction (-), and show how the rotations can be coterminal & beyond the -2pi...2pi range...here's what I got: desmos.com/calculator/d6e… @desmos #iteachmath #MTBoS

@CmonMattTHINK In my HS math classes we make lots of use of @GraspableMath , I love how it allows for most anything you can think of following algebraic rules. This is also helpful for my students showing digital work with Algebraic thinking

... is that we should absolutely be constantly reminding our students that there are many routes to "the answer," not just one. I know, this feels like Math Pedagogy 101, but I am still seeing the adverse effects of The-One-Right-Way-Thinking in my own students. [5/5]

I have not taught Alg I in a long, long time. But my children (7th grade) are now starting to learn about solving simple equations, and I am frustrated by what seems to me like an insistence that there is one way to solve equations. This thinking is so damaging. [1/5] #iteachmath

@heidifessenden @RPhillipsMath @cluzniak FWIW with my AP Calc students we used area model division, long division can work but the area model helps track and self check better IMO. (mathrecreation.com/2009/03/dividi…, youtube.com/watch?v=8cQaRv…) #iteachmath

@RPhillipsMath @cluzniak I don’t think the argument is that they shouldn’t understand division. They definitely need to understand it and use partial quotients to divide larger numbers. But for complex long numbers, I agree that the algorithm seems unnecessary.

Do we still need to teach the long division algorithm?

Made @Desmos Geometry tool to show markings on a shape for congruence , right angles, and parallel relationships. Feel free to use as you see fit. Embeds in Activities too. Feedback on quirks / improvements welcome: desmos.com/geometry/v0jtp… #iteachmath #desmosgeometry #mtbos

The Desmos Global Math Art Contest is here! Have a graph that you’re proud of? We’d love to see it. Submissions open December 1st. Learn more at blog.desmos.com.

Let the kids build some intuition before you “teach” them anything. Pretty please. #ElemMathChat

@EckertKathleen When you hold meetings…plan for it like a good lesson, or at least try to model good teaching

What can school leaders do to retain teachers? Please share your ideas and thoughts.

@nomad_penguin Examples: “Nice shoes” can be “I hadn’t seen those shoes before” or “I like your haircut” can be “did you get a haircut”. Let the student state the value. And play off of that. Don’t tell them their value but help them celebrate their own value.

@nomad_penguin Noticing (being seen). Another teacher taught me that when greeting a student we don’t need to say anything evaluative.

A pre-service teacher just asked me the most excellent question, so I will ask it to you. "In your experience, what has helped you most in building good relationships with students? If you could converge it to just one specific thing?"

This is a good webinar. Helps framing the structure in how it all works in CL.

Happy to be a father and be with the man that taught me how to be a father. #happyfathersday to all the dads out there.
