How do we do this "new" way of dividing?

Here are 4 common small mistakes I see in math class. What are some others?

Here's one strategy that can help improve your mental math

My response to "Why do you keep drawing so much? Just teach them the formula!"

Today ,Gr. 2&3 students @tdsb Stanley PS confidently approached open-ended questions and showed such enthusiasm for using double number lines when solving multiplication problems. #Mmath work & engagement was simply impressive! @TDSBmath @LizBHolder @ldilworth1

Thank you to the parents who joined us @TDSB 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 & children working together to solve math problems! @TDSBmath @LizBHolder @ldilworth1

Every morning, the Gr. 2/3 students @tdsb 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 @ldilworth1 @LizBHolder #math

Today @StanleyPStdsb, Math PLC focusing on High Impact Instructional Practices. The format: observation of 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 @LizBHolder @ldilworth1

Great learning happened in Gr. 2, 3 & 4 classes
@TDSB_Topcliff and @GracedalePS as students engaged in building and guessing the rules of the growing patterns created by their classmates! @TDSBmath @ldilworth1 @LizBHolder

How can we count efficiently? Counting collections to start the Number Sense unit that will focus on representing, composing and decomposing numbers. Grade 3s @GracedalePS came up with amazing observations! @TDSBmath @LizBHolder @ldilworth1

Day 1 of facilitating with @codru_c 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. @TDSBmath @LizBHolder @ldilworth1

Honoured to emcee the 61st annual Aurora Art Show & Sale Opening Gala in partnership with SOYRA tonight at Town Hall. Congratulations to all the award winners—our community is truly filled with incredibly talented artists. Be sure to stop by Town Hall this weekend to see all the beauProud

The double number line: quite "popular" among the @tdsb Gr. 3 students. An effective visual tool to help solve multiplication, division and ratio-related #math problems! @Jason_To @mervisalo @LizBHolder @TDSBmath

Despite the winter today, teachers in North York @tdsb had an energy-filled Day 2 Building Foundational #Math Skills! We analyzed the lasting usefulness of Up & Over 10 & Constant Difference & played games to promote (+/-) strategies. @TDSBmath @LizBHolder @mervisalo @Jason_To

Gr. 4/5s @TDSB Flemington PS practised equipartitioning a length w/ the Unit #Fractions Paper Strips task. This hands-on activity was engaging and super fun for all students & a great assessment opportunity for the teacher! @mervisalo @Jason_To @LizBHolder

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.
