I was busy at #OAME2024 this year as I presented 5 sessions. A bunch on Desmos & Desmos Classroom (Activities for Gr7&8 and Secondary, plus Geometry and 3D stuff) as well as one on Assessment values. All the slides are here

Really enjoyed day 3 of Unlocking Fractions Understanding from TDSB Mathematics & Numeracy ! Got to dive deeper into fraction density and equivalent fractions. Learned lots to bring back to the classroom, especially a fun equivalent fractions card game! Jason To | 杜澤信 Mervi Salo Codruta Colceriu

Learned a lot today at TDSB Mathematics & Numeracy Unlocking Fractions Understanding PD from Codruta Colceriu and the rest of the Math Learning Partner team! From partitive and quotative division to equivalent fractions. Can’t wait to take what I learned back to the class! Jason To | 杜澤信 Mervi Salo

The link between math achievement & motivation is a two-way street. The high-impact practices embedded in the thinking classroom framework get to both in such a coherent manner.

🙏🏽 Codruta Colceriu & the rest of Toronto District School Boardmath’s Math Learning Partners for supporting so many Toronto District School Board teachers.

If we write fraction division like this, people may see why 'keep change flip' works

Day 1 of our Building Thinking Classrooms Winter session @TDSB North York cluster. Some phrases to describe the day: learning from each other, great questions, rich conversations & positive attitude. See you all on Day 2! TDSB Mathematics & Numeracy Jason To | 杜澤信 Mervi Salo Lisa Dilworth Tiffany
