Most of my most magical math moments have happened during number talks! #numbertalkschat
— Ann Elise Record (@AnnEliseRecord) March 30, 2017
I’ve found that once teachers see the benefit, they are committed to implementing NTs. #NumberTalkChat https://t.co/MUF35LhC4U

Time for a warm-up Q! How could you solve this problem? How did you see it? #NumberTalksChat pic.twitter.com/hgxAzHQemT

I knew that 4/8 is 1/2, so I took it way from the 5/8 to combine with the 1/2 to make 1. So, 1 1/8 . #numbertalkschat
— Ann Elise Record (@AnnEliseRecord) March 30, 2017
#NumberTalksChat A0 I saw 4 dots from 1st set and 5 from 2nd set, so 9/8
— Jennifer Hinrichs (@MrshinrichsT) March 30, 2017
Q0: using the model, i though 4 dots (1/2) plus 5 dots makes 9 dots. 8 fills up a set, so 8 1/8 #NumberTalksChat
— Jamie Strang (@Elementarist) March 30, 2017
I see 1 + 1/8#NumberTalksChat @Math_Solutions pic.twitter.com/N0B9O31eg6

Q1: How do you help students see that mistakes are an important part of learning in your classroom? #NumberTalksChat pic.twitter.com/VRrtM5mO5K
— Math Solutions (@Math_Solutions) March 30, 2017
A1: I love @joboaler ‘s work, so I make sure to teach my Ss how their brain works. Mistakes are when our brain grows. #numbertalkschat
— Ann Elise Record (@AnnEliseRecord) March 30, 2017
#NumberTalksChat it really frees the students to think about numbers and make their own decisions
— Naomi Isaac-Simpson (@nisaacsimpson) March 30, 2017
A1: creating a safe classroom atmosphere that values multiple strategies and encourages risk taking #NumberTalksChat
— Kelly Wegener (@WegenerKelly) March 30, 2017
A1: Students have experienced me making mistakes and I help my Ss realize that mistakes are learning opportunities. #NumberTalksChat
— Chris Quinn (@ChrisQuinn64) March 30, 2017
#NumberTalksChat A1 take time to create a learning community. Cocreate”rules”. I model my thinking. Including mistakes!
— Jennifer Hinrichs (@MrshinrichsT) March 30, 2017
Involving the whole class/group in the conversation & asking for help from everyone in finding mistakes so we can all learn #numbertalkschat
— Ann Dominick (@Dominick_Math) March 30, 2017
Q2: What ideas do you have for when the sharing of student strategies in a #numbertalk doesn’t go as anticipated? #NumberTalksChat pic.twitter.com/OaxliyNTf0
— Math Solutions (@Math_Solutions) March 30, 2017
A2: sometimes you roll w/ it “that’s interesting tell me more”…sometimes you table it for later #NumberTalksChat reflect on what happened
— Jamie Strang (@Elementarist) March 30, 2017
#NumberTalksChat A2: Unpackng w/ Ss what growth mindset is. Need 2 model it daily & capitalize on mistakes. Investng time in buildng culture pic.twitter.com/LqBo4B4vc2
— Maria Riverso (@RiversoMaria) March 30, 2017
A2 I listen 1st. Then try to clarify their thinking sometimes in a clearer way. Then ask if that is what they were saying. #NumberTalksChat
— Kenny Hall (@Kennygarten) March 30, 2017
A2: Asking Ss to Turn and Talk about what do you understand and what questions do you have #NumberTalksChat
— Sherry Parrish (@numbertalks) March 30, 2017
A2: Go with it! Often, Ss take the conversation to a better place than I anticipated! #NumberTalksChat https://t.co/b5OnN8tzcD
— Jenna Stilwell (@Stilwells_Class) March 30, 2017
We discuss daily that without mistakes we do not learn. We learn from each Other’s mistakes and help our classmates. #NumberTalksChat
— Tammy Krutzfeldt (@TKrutzfeldt) March 30, 2017
A2:There is something mathematically valuable in all students work and sharing. NTs are better when the unexpected occurs. #numbertalkschat
— Devin Anderson (@devin_andersond) March 30, 2017
Q3: How do you help students make connections between computing with whole numbers and computing with fractions? #NumberTalksChat pic.twitter.com/FItKLQOwVc
— Math Solutions (@Math_Solutions) March 30, 2017
A3: start with skip counting with fractions…. 1/3,2/3,3/3 #NumberTalksChat
— ElementaryMathTeach (@Kidsmathtalk) March 30, 2017
Number lines (floor-size that we can walk), fraction strips, Quisanaire rods are all helpful tools. #NumberTalksChat https://t.co/igXQgLwNZ0
— Chris Quinn (@ChrisQuinn64) March 30, 2017
A3: Asking Ss, “Will this strategy for multiplying whole #s also work when multiplying fractions?” #NumberTalksChat
— Sherry Parrish (@numbertalks) March 30, 2017
Q3 Connect strategies like decomposing to fractions. Equivalence is a key. @Math_Solutions #numbertalkschat
— Lisa Bush (@lBush11) March 30, 2017
#NumberTalksChat A3: Try a strategy w/ whole numbers. Then predict whether the same would apply w/ fractions. Conjecture. Test.
— Maria Riverso (@RiversoMaria) March 30, 2017
Q4: Are there any shortcuts Ss might use in this problem that might mask bigger ideas of place value and equivalence? #NumberTalksChat pic.twitter.com/vdHA06AADO
— Math Solutions (@Math_Solutions) March 30, 2017
In as thinking 500-64 would help me. I think if Ss just try to line it up and subtract might mean not full PV understanding #NumberTalksChat
— Kenny Hall (@Kennygarten) March 30, 2017
A4: Changing 0.5 to 0.500 #NumberTalksChat https://t.co/sCO6HKzyEA
— MAdams (@MelroseCurricul) March 30, 2017
A4:Many Ss would “add” zeroes to the .5 then use the std alg; would love to see adding up, decomposing .5 to .499 + .001 #NumberTalksChat
— Sherry Parrish (@numbertalks) March 30, 2017
S adds two 0’s to 0.5….0.500 to more easily compare to 0.064..but some would say 64 is bigger than 5. #NumberTalksChat https://t.co/DyhQo574cv
— Chris Quinn (@ChrisQuinn64) March 30, 2017
#NumberTalksChat A4
Add 0.036 to both numbers to make a friendlier subtrahend
Making 0.536 – 0.1 = 0.436— Margie Pearse (@pearse_margie) March 30, 2017
Q5: How might “rules” for dividing decimals interfere with students’ fractional understanding? #NumberTalksChat pic.twitter.com/O1Z7JmcJ7s
— Math Solutions (@Math_Solutions) March 30, 2017
A5: It’s easy for Ss lose meaning and reasonableness of answers when blindly following rules/procedures #NumberTalksChat
— Sherry Parrish (@numbertalks) March 30, 2017
#NumberTalksChat A5
Some Ss might be more concerned about “moving decimal places” and not about whether what they are doing makes sense— Margie Pearse (@pearse_margie) March 30, 2017
If Ss are only following “rules” it’s hard to predict what a reasonable answer would be #NumberTalksChat
— Ann Dominick (@Dominick_Math) March 30, 2017
A5: I find that building a stronger sense of numbers helps students make better sense of “rules”. #NumberTalksChat https://t.co/ZqT6Ij5hfl
— Chris Quinn (@ChrisQuinn64) March 30, 2017
Q6: What do you listen for to know if a student is using the standard algorithm for dividing decimals with understanding? #NumberTalksChat pic.twitter.com/RopCFlPN5J
— Math Solutions (@Math_Solutions) March 30, 2017
A6 Following rules throws number sense out the door leading to errors and little reasoning. #NumberTalksChat
— Kendra Thurmond (@prettymathgirl) March 30, 2017
@Math_Solutions You hear students using place value language like tenths and hundredths when they say the numbers. #NumberTalksChat
— marymitchell (@marymitchell) March 30, 2017
A 6: Proportional reasoning, place value understanding #NumberTalksChat
— Ann Dominick (@Dominick_Math) March 30, 2017
A6 Reasonable estimations #NumberTalksChat
— Sandy Mueller (@sfmueller) March 30, 2017
Q7: What are some questions you could ask to help students construct the ideas behind these rules and procedures? #NumberTalksChat pic.twitter.com/fV1rRjUEHE
— Math Solutions (@Math_Solutions) March 30, 2017
A7: How can you represent with a picture? #NumberTalksChat @Math_Solutions https://t.co/BEfng0N4JH
— Genni Steele (@gennisteele) March 30, 2017
@Math_Solutions #NumberTalksChat Does this strategy work in every situation?
— Maggie Lee McHugh (@mlmchugh) March 30, 2017
Can you represent/model how you solved it in more than one way? What connections to other strategies do you notice?#NumberTalksChat
— Kendra Thurmond (@prettymathgirl) March 30, 2017
A7 Will it always work? Who would like to prove your thinking? #NumberTalksChat
— Ann Dominick (@Dominick_Math) March 30, 2017
#NumberTalksChat Really focusing on what Ss see and how they see it. Giving lots and lots of opportunity for turn and talk
— Krista Sarmatiuk (@sarmatkd) March 30, 2017
Q8: Have you heard any noteworthy comments from a S about a recent #numbertalk? Extra brownie points for sharing a photo! #NumberTalksChat pic.twitter.com/vL1LCQP21u
— Math Solutions (@Math_Solutions) March 30, 2017
A8 “so you just go on Twitter to get your Number Talk” #NumberTalksChat pic.twitter.com/Nd06SETzaf
— Toni Chieppa (@tmchiepp) March 30, 2017
A8: #NumberTalksChat My Ss loved #MathTalks so much we make an ongoing iBook of strategies they can use on their math work at any time! pic.twitter.com/0zEINOcK2n
— Maggie Lee McHugh (@mlmchugh) March 30, 2017
A8: Student comment about NT: “I learn best by sharing my thinking out loud and by listening.” #NumberTalksChat
— Chris Quinn (@ChrisQuinn64) March 30, 2017
A8: can you come again tomorrow? #magicwords to a math coach #NumberTalksChat #notmypicture pic.twitter.com/jXjaoEzLKq
— Rebecca Enright (@MsEnright) March 30, 2017
@Math_Solutions Ss had their own storyboards to model with during the talk and the storyboard turned into a centre later @LLB_315
