It's hard to think about addressing this without somehow incidentally shaming the teacher. The question tells you a lot about their beliefs about teaching - so different than mine - but might make me miss the concern for student learning. This teacher really believes the students are worse off for not hearing it from the teacher. Dave Coffey is always urging shift vs huge change, so I try to think: is there a shift here?

I've tried: Your perspective on this math is so valuable - you are the expert problem solver in the room. So it's definitely appropriate for you to share your thinking. What I worry the most about when that's up front is that it removes the need for students to think because the expert already gave their opinion. What do you think good timing might be that gives the students encouragement to wrestle with these ideas themselves?

I hope that's authentic. I want to respect these teachers' ideas just like I want them to respect their students'.

Math Teachers at Play 108
I requested to host 108 because I have an absurd attachment to this number. 108 beads on a Tibetan Buddhist Mala. 108 pressure points in the human body. 108 suitors courting Odysseus' wife Penelope. An official Major League Baseball baseball has 108 stitche...

I miss them! But your Desmos work is a delight, so life takes away and gives.

Lenten Teaching
Two things have me thinking about lent and teaching. The first is just lent itself. An ancient word for spring, it's a fascinating spiritual practice; the idea of preparation for a holiday by engaging in disciplines. The traditional disciplines are prayer, ...

Math in Action 17
A highlight of February in these parts is Math in Action . Our local, 1 day math fest. Having been at the U for 20 years now, part of it is just great reunion, with our former students coming back to present and knock 'em dead. The last two years have felt ...

7.5 x2 is 15, x 2 is 30, x 3 is 90. So x12 (if it can keep up the pace). 50 x 12 is 600, so 600 ft.

Pentiremeter
New game! But a story first. The idea came to me just before class, and the preservice teachers in my geometry & data for elementary course were willing to try and playtest. (Thank you!) The class before we had defined and catalogued all the pentominoes. (S...

Mathematical Autobiography
For Tracy Zager's amazing new book ( book , FaceBook , forum , Twitter ), she's asking for mathematical biographies . I used to ask my preservice teachers to do that, but haven't in a while. Thinking that I'm going to again for this read... so I should, too...
