A4: How often do we get to slow down in the classroom and just focus on one thing? Everyone in the room? I'm guessing not often. "You have one job. Breathe consciously." #ElemMathChat

A2: I could tie A and B together by playing Twister on B with my four fingers - each finger on a red dot. #ElemMathChat

A1: I wish I looked nearly that graceful doing those yoga poses! My fav is D, since I find it most challenging. I like moving between A and B. Very focused and doable, but soothing. #ElemMathChat

Hey #ElemMathChat. Annie joining from suburban Philly. I'm a math ed lifer. I want the first image to be the thing today, so I can tie up a few loose ends tonight before bed!

Hey #CMCMath! Get a shirt! Ends this Sunday, so act now! tinyurl.com/NoticeWonder...

Think a #NoticeWonder shirt would be awesome? It could be a reality if you move fast! The store is open today through Nov 9. Hopefully enough styles, sizes, and colors to suit everyone. #ITeachMath #MTBoS

Hey #NCTMATL25! Want to start your conference with some math thinking? Join me at 8 am Thursday (yes, in 8.34 hours) to explore dynamic quadrilaterals. Were you at #NCTMGameNight? My session’s in the same room.

Pretty sure I have never seen a tetradecagon in the wild until now!

A12: This is so thoughtful..we can't just have a rule that says "distribute if you used addition to break up one number, but not if you used multiplication". That's not helping anyone thing about "why". #ElemMathChat

A11: When it gets applied procedurally without being backed up with sense-making, it can get pretty messed up. As in students just "do" the wrong thing - not multiply all the decomposed parts by the initial multiplier, for example - because they are missing the underlying concept. #ElemMathChat

A10: Makes me wonder how much the whole denominator thing can freak people out. "Are we allowed to write that second line? How do you know it's okay?" Or am I just making that up? #ElemMathChat

Also A9: a difference is that the left one has a single numerical answer in the end, and the red one is in terms of x. #ElemMathChat

A8: I see the "multiplication wrestling", or area model, or partial products in each. Each part of Number A multiplied by each part of Number B, even when we don't know what they are and have to use an x. #ElemMathChat

A6: As a mature adult, I was glad to learn the partial products algorithm, which I'd never seen before, but it seemed much less mystical than the traditional "standard" algorithm, where you sort of ignore place value and just know when to "bring down" a 0 and when to carry a 1. #ElemMathChat

Way back I was digging into Everyday Math to support some schools, and in Gr4 they called one method "multiplication wrestling" - basically each part of 27 (or 20 + 7) would wrestle with each part of 33 (or 30 + 3). #ElemMathChat

A5: One is drilling down, "What did you do? Tell me more!" etc., and the other is "Why did you pick that way? How did you decide?" Getting them to reflect on WHY they did what they did, beyond just what they did. #ElemMathChat

A3: I guess I would be less inclined to do the subtraction one, and the (10+5+3) one, reflexively, when the other two are what I would think of first. #ElemMathChat

A2: My reflex is to do 4*10 + 4*8, so 40+32. But then I wondered about 4*9 + 4*9, so I only have to do one multiplication problem. Then I ask if I want to add 40+32 or 36+36, since arithmetic isn't my strong suit. #ElemMathChat

A1: I think of it as taking a number apart (and then putting back together). Like 16 is 10 + 6. Or 8 + 8. #ElemMathChat

Hi #ElemMathChat! I'm Annie, joining from suburban Philly. I'm mostly a consultant. Today I saw a math educator colleague from the very first post-college job I had - first time I've seen her in 15+ years. Great memories and conversation.
