"In this resource you will see teachers who think deeply about ways to help students develop proportional reasoning. They determine how to make ideas explicit for students, to help them "notice things that would not otherwise be seen."

At the same time, they develop their own capacity as learners and teachers."-- Curriculum Services Canada.
