Love that I can make games for my online middle school methods class on Polypad. Designed this game for today. Such fun and great opportunities for reasoning and estimating in upper elementary. Polypad – 3-Digit Targets mathigon.org/polypad/iRrbxn… via Mathigon

Well done, Herbie. Pebbles is such a lovely challenge but we've never seen that approach before! We've uploaded some examples of other children's work and teacher notes with the original problem here nrich.maths.org/48 Faculty of Mathematics - University of Cambridge Faculty of Education, University of Cambridge

Looking good! Thanks for sharing student thinking with us! For those interested in checking it out, have a peek here: tapintoteenminds.com/3act-math/cove…

Mmm… perfect rectangle month. This year February is an exact rectangle because it starts on a Monday and it’s not a leap year. But it’s not as rare as I see people claiming (every 200 years apparently‽), it’s about every 10 years. The previous was 2010 and the next is 2027.

The interactive multiplication grids on Polypad can help you visualise multiplying integers, decimal numbers or fractions. You can even multiply numbers in bases other than 10! polypad.org/LqfRpJ8EnNZP9A

Sixth grade math teachers! I've made Open Middle Depth of Knowledge matrices to show how a single problem can replace an entire worksheet in sixth grade math. Download it now here: robertkaplinsky.com/depth-of-knowl… #MTBoS #iteachmath

Q1: Introduce yourself plus what & where you teach. + How has the way in which you have students take notes changed over time? What happened that prompted the change? #ThinkingClassroom

Reflecting on BTC framework with my Ss. I feel toolkit #1 and #2 are working well and parts of #3. Working on: Consolidating from Bottom Ss writing meaningful notes Navigation instruments to help Ss see where they are and where they’re going #ThinkingClassroom Peter Liljedahl

Toolkit #1 BTC -Give Thinking Tasks -Form Visible Random Groups -Use Vertical Non-Permanent Surfaces “These three practices are all about creating a new set of norms in the room that necessitate that the system change, and with it, your students” p. 284 #thinkingclassroom

A great day at home with the family yesterday! Really special to play cards with Sophie! Charlie is learning too!!!

I wasn't shocked when Pam Harris's Math Perspectives quiz came back saying my "growing up" perspective of mathematics was procedural! Thank goodness I've been shifting that perspective over this past decade! What was your perspective growing up? mathisfigureoutable.com/xyz

CCRCE Mathematics - Cindy Ferguson CCRCE Pictou Academy @melomgoogoo So happy that this activity is being used in Nova Scotia schools. All these years later, Dianne’s knowledge is still inspiring youth. David Wagner You can try this too! Just check out this Desmos activity: Dianne's Quill Boxes! teacher.desmos.com/activitybuilde…

New blog post! Lots in this one. mathforlove.com/2021/02/conjec…

There is so much great stuff in this post that goes beyond #thinkingclassroom. And I love you use of “centre of gravity”. What a great metaphor.

Concrete manipulatives are NOT reserved for a struggling student. Use them to Fuel Sense-Making! Learn how with the Make Math Moments 3-Part Framework: makemathmoments.com/framework #MTBoS #iteachmath #msmathchat

Enjoyed learning alongside @ScotsburnE teachers through the painted cube task, unpacking #thinkingclassroom framework. Very inspiring to see and hear them work together on this task and reflect on toolkit#1 and book study! Peter Liljedahl Michelle McCarron (she/her)
