Today, Gr. 2&3 students @tdsb.on.ca Stanley PS so confidently approached open-ended questions and showed such enthusiasm for using double number lines when solving multiplication problems. #Math work & engagement was simply impressive! @mrjasonto.com @tdsbmath.bsky.social

Thank you to all Parents who joined us today @tdsb.on.ca Sheppard PS to learn about the various strategies for adding numbers & ways in which they help to build strong number sense. So nice to see parents work together with their children to solve math problems! @tdsbmath.bsky.social @mrjasonto.com

Every morning, the Gr. 2/3 students @tdsb.on.ca Flemington PS choose a math game to play with a partner or small group. What an engaging way to start a new day of learning & build love and motivation for math! @tdsbmath.bsky.social @mrjasonto.com

Today, teachers @tdsb.on.ca Stanley PS had a Math PLC focusing on High Impact Instructional Practices. The format: observing 2 co-taught lessons (Gr. 2/3&3/4). The outcome: rich learning experience for teachers in classrooms with students deeply engaged in math! @tdsbmath.bsky.social @mrjasonto.com

Great learning happened in Gr. 2, 3 & 4 classes @tdsb.on.ca Topcliff PS and Gracedale PS as students engaged in building and guessing the rules of the growing patterns created by their classmates! @mrjasonto.com @tdsbmath.bsky.social @tleeteach.bsky.social

How can we count efficiently? Counting Collections to start the Number Sense unit that will focus on representing, composing and decomposing numbers. Grade 3s @tdsb.on.ca Gracedale PS came up with amazing observations! @mrjasonto.com @tdsbmath.bsky.social

Day 1 of facilitating with @codruc.bsky.social on Shaping Algebraic Reasoning with grade 7-10 teachers. Such a great PD on patterning and linear relations. Great activities to bring back to the class and do with students. @mrjasonto.com @tdsbmath.bsky.social

The double number line: quite popular among the @tdsb.on.ca Gr. 3 students. An effective visual tool to help solve multiplication, division and ratio-related #math problems! @mrjasonto.com @tdsbmath.bsky.social @mervisalo.bsky.social

Despite today's winter weather, teachers in North York #TDSB had an energy-filled Day 2 of Building Foundational #Math Skills! We analyzed the lasting usefulness of Up & Over 10 & Constant Difference & played games to promote various (+/-) strategies. @tdsbmath.bsky.social @mervisalo.bsky.social

#Fractions through Paper folding today in the 4/5 class @Flemington PS. This hands-on activity was engaging and super fun for all students; at the same time: a great assessment opportunity for the teacher! @tdsbmath.bsky.social @mrjasonto.com @mervisalo.bsky.social

Every time there’s been an A-ha moment, an understanding of the math concept as a result of work with concrete objects, I thought of Maria #Montessori’s belief from almost 100 years ago: a child’s “hand activities” and “psychological development” are so closely entwined. @tdsbmath.bsky.social

Great conversations re: the importance of teaching various strategies @ Building Foundational #Math Skills in the Early Years, Day 1. A very special Thank You to @tdsb.on.ca Gosford P.S. staff & students for offering their beautiful library for our learning! @mrjasonto.com @mervisalo.bsky.social

Valuable learning during PLCs @tdsb.on.ca Topcliff PS. Teachers & Principals observed a Gr. 3 math class & reflected on lesson & #math environment. Goal: improving the math program. Amazing student engagement in solving & especially creating math problems! @mrjasonto.com @tdsbmath.bsky.social

And also from today: The Gr. 3/4s @tdsb.on.ca Stanley PS used Constant Difference to solve subtraction problems! So proud of these kids! 👏@tdsbmath.bsky.social @mrjasonto.com

Hi! This is my first #Bsky story with students & teachers who love doing #Math … Today, Gr. 2s @tdsb.on.ca Lamberton PS told me that the triangle 📐 is the polygon with the least number of sides & all polygon names come from Greek! 👏👏 @mrjasonto.com @tdsbmath.bsky.social
