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

Over the course of this year, our Math Learning Partners (MLPs) have had the incredible opportunity to learn with Dr. Ruth Beatty through a series of sessions focused on deepening mathematical understanding.
In a recent session, Dr. Beatty guided us through powerful work on interpreting intersecting trend lines using rich story problems—an approach that invites students to explore math through context, relationships, and narrative.
Her work pushes us beyond procedural fluency toward relational understanding, where math becomes a tool for storytelling, comparison, and community connection.
This learning has strengthened our MLPs as math leaders and directly informed our system-wide professional learning on algebraic reasoning.
Grateful to Dr. Beatty for her continued partnership and generosity.

Late post, but had an amazing learning session with @ruthbeatty11 on progression from patterning to algebra. Easy strategies that can be used from elementary to high school!

Such a great learning experience! Can’t wait to start implementing strategies into the classroom and share with other teachers!
Math Learning Partners from @TDSBmath begin their journey from patterns to algebra with the amazing @ruthbeatty11.
A main takeaway from day 1: describing a pattern rule like “start with 3 & add 2 each time” does not promote algebraic or multiplicative thinking in students. Instead, focus on the relationship between the number of items and the position number to support generalization of the pattern (e.g. position #1 has 1 group of 2 and 3 more, position #2 has 2 groups of 2 and 3 more…position #n has n groups of 2 and 3 more).
