Keith Van De Keere believes that when math teaching is focused on deep understanding of the big ideas, students have a better chance of experiencing enduring success, and teachers can better see the natural flow between teaching and assessment. To promote and support this kind of teaching, Keith takes these ideas into K-9 classrooms to work with teachers to modify and adapt what the teacher is already doing by making the focus more about getting students to investigate Math Big Ideas and to observe and analyze the math in action. The focus of lessons is on conversations within a community of learners with a goal of understanding and improving number sense rather than just having ways to get answers. To do this, teachers who work with Keith are taught how to design lessons that are infused with visual and verbal experiences. Keith also helps teachers become "kid watchers" and improve their ability to "listen in" on conversations and use them as formative assessment moments. Keith has worked with Dr. Cathy Fosnot, who is a North American leader in constructivist learning and changing the culture of math classrooms. He has also worked with K-9 teachers and school divisions in Ontario, Manitoba, San Francisco and Hartford but does the majority of his work supporting teachers in North Central Alberta.

AllProportional reasoning is the big brother/sister of multiplicative thinking. It is based on multiplicative thinking but becomes much more when numbers other than whole numbers and ideas like ratios and algebraic thinking are introduced.
Proportional reasoning is a lens that opens up a whole new world of math possibilities. Many problems become easier to imagine and solve through this new lens. It is one of the best indicators of likely success in further mathematical pursuits (Lamon, 1999).
It forms the backbone and is at the heart of the Div. 2 mathematics curriculum, permeating all strands of mathematics. It is linked to almost all Division 2 outcomes and is the common thread between Big Ideas.
But research suggests that over 90% of students entering high school are “stuck” thinking additively in situations best served with proportional thinking and cannot reason well enough to learn mathematics and science with understanding.
What can we do to better prepare students for a world filled with proportional thinking?
How can we make this the most common language in Division 2 Classrooms?
How can we make it at the heart of every lesson?
These sessions provide many ideas that will assist you in fostering this shift from Grade 3 onward.
