@RiversoMaria @marian_small I bet this was a good chat!

@marian_small: "I believe we want to message to Ss that math is a subject where there r often many possible responses to a task & u can show creativity just by answering a math question. That means we have to change the tasks we use." 👇🏼 Sharing some notes #OAME2025 #dpmath

@realJ_Mitchell Marian Small is the bomb! Always has been.

I think about this presentations by Marian Small a lot.

@ddmeyer 35 Make a connection with each kid no matter how small-do this by getting them doing a task within 5 minutes in groups

Help me settle a bet: 👉 What year of teaching is this for you? 👉 What is your #1 goal for your first day of school with students?

@robertkaplinsky @ddmeyer Me too.

@ddmeyer's TED talk changed how I looked at math ed. I had been so comfortable with teaching the way I was taught... ted.com/talks/dan_meye… #MTBoS

@pwharris 2/8ths is a quarter. A quarter of 4/5ths is 1/5. That is a cleverly designed question.

It's time for #MathStratChat! Rules: post your favorite or a clever solution! It's also fun to comment on other's strategies. Tell us about your reasoning. Like/Retweet so others can see! #MathIsFigureOutAble #MathStratChat #MathChat #MTBoS #ITeachMath #MathEd #Mathematics

@ChantalRos15865 Hi Chantal Can you dm me your email.

@AlexOverwijk Looking for ideas or suggestions for a final collaboration assessment for my MDM2D classes. It's my first year having my Thinking Classroom up and running, so I'd like to find a final collaboration assessment that covers most of the course content. Any suggestions?

Collaborative Whiteboard assessment today in #MHF4U Trying to evaluate what I value-still!!! #ITeachMath #mtbos

@the_dramamama @realJ_Mitchell Stoking fear-was that intentional? 😂

This came up in my “For You” and boy howdy could something be less for me…

@steve_freshour @kprinzloo For those who continue to struggle with individual test I offer alternate assignment. Multiple opportunities built into all this naturally. BTW I spiral curriculum-so multiple big ideas from the course on each assessment-why I use the word cycle versus unit Hope this helps n/n

@steve_freshour @kprinzloo OR high WB vs low individual OR low WB vs high individual Then I have a conference with them to work on differences. Basically I have traded a review period for WB assessment and still have individual data as well. Very open and transparent. 4/n

@mathwithmstong 15 pairs for WB assessments-normally 10 boards of 3. Need to roll my portable WB (which hold 3 pairs) into the middle of the room-so two of the pods (6 chairs and desks go on top of the other pods

@Andy_CK_Shin @pgliljedahl Things have changed since. Built two portable whiteboards that are moveable. No longer covering any light. Picture from pandemic so desks are apart.

@AlexOverwijk @pgliljedahl Oh, man....sacrificing natural light for whiteboards. That's a hard one for me to do.

A few secs of a #thinkingclassroom in action based on research by @pgliljedahl peterliljedahl.com/wp-content/upl… #mtbos

@realJ_Mitchell We have gifted destreamed classes. 😞

If you are destreaming in #OntEd but your school offers a pre-IB or pre-AP pathway in grade nine you are still streaming.

@mathhombre Some great circles!!!!

Some great circles. @AlexOverwijk was invoked.

@SueSantiagoWrit Having them experience it always opens one’s mind-get a good task and workshop BTC

@AlexOverwijk My challenge is to show secondary teachers the benefits of BTC, having teachers consider doing a 180 with their practice is a big ask. Trying to figure out how to broach the subject. Any advice is welcome.

I'm searching for a short video that shows a HS math class building their mathematical thinking @AlexOverwijk? #mathEd

@cafedepruner @sfueducation @pgliljedahl congratulations Michael!!

What a summer! Finally finished my Ph.D. in August @sfueducation . A huge thank you to @pgliljedahl for his guidance over the past 5 years. I can’t believe it’s done!!
