@geonz @sophie_brady Neat! This is making me wonder if every strategy is about finding something else that's equivalent.

[Barry Rust @_barry_rust_]

@Mcoaty @geonz @sophie_brady I'm curious about the ratio/proportionality ideas too! I don't know enough about that stuff. So 12x4 is equivalent to 6x8 and they multiply to the same product. But the ratios between the factors or a factor and the product are really different?

[Barry Rust @_barry_rust_]

@Mcoaty @geonz @sophie_brady Is the associative property of multiplication what you're looking for? Could look like Matt's second model, where 6x15 becomes 2x(3x15). It can look like doubling and halving, but it's the same property we use when we turn 2x30 into (2x3)x10 or 40x50 into (4x5)x(10x10).

@kvanduzer @TracyZager haha I'm in!

[Barry Rust @_barry_rust_]

@pearse_margie @a_schindy Thank you for sharing these!

[Barry Rust @_barry_rust_]

@heidifessenden @kvanduzer And thanks for the kind words on Math Collective! Always looking to grow, even out of state!

[Barry Rust @_barry_rust_]

@heidifessenden @kvanduzer This explains it all. I remember some classes with your sister. Did we make the connection then?

[Barry Rust @_barry_rust_]

@heidifessenden @kvanduzer Ha! I'm a lurker here and saw you and thought "I know her!" But I couldn't remember if Carleton or Bank Street.

Thanks all for making my first chat a great one! #tcmchat

[Barry Rust @_barry_rust_]

@DrKChilds Yes--like when we explore ideas in math, we may act them out as well as talk/write about them. #tcmchat

[Barry Rust @_barry_rust_]

A4 The article mentions the EM site as a source for videos. Any other good ones? Like starting with neutral vids b/f taping ourslvs #tcmchat

[Barry Rust @_barry_rust_]

A3 My experience with lesson study has been that its helpful to start with a goal that everyone has agreed on at the outset #tcmchat

[Barry Rust @_barry_rust_]

@MandyMathEd Yes! I can find myself wishing for a sentence starter when I'm asked to talk about something new or in a new way #TCMchat

[Barry Rust @_barry_rust_]

A2 Many ways we try. One thing is providing the same concrete tools for range of topics, trying to make connections when we can. #tcmchat

[Barry Rust @_barry_rust_]

@zack_hill Agree! I loved imagining doing this video work with my Ts and that question made me see the connection between the two. #TCMchat

[Barry Rust @_barry_rust_]

Lots of lesson studies, with small group designing the lesson and a larger group observing based on designers' goals. #TCMchat https://t.co/sEF0UtL1VG

Q1 How do you (or your colleagues) create #math professional learning opportunities? #TCMchat #MathPLC

[Barry Rust @_barry_rust_]

Hi, Barry from Brooklyn NY. Math coach grades 3-5. Looking forward to my first twitter chat. #tcmchat

[Barry Rust @_barry_rust_]

@pcipparone @kvanduzer also makes me think how nice your idea of math lab meet ups are.

[Barry Rust @_barry_rust_]

@pcipparone @kvanduzer yeah, I think that's what I was trying to get at. Gotta meet the learner where they are. In the zone.
