Proportional Reasoning prepares the transition from a primary focus on arithmetic and skills
with algorithms (typical of elementary and middle school) to a focus
on algebra, where students use multiplicative, as well as additive,
Professional Development Goals
- Explore the relationship between proportional reasoning and algebraic thinking.
- Understand that students who appear to reason proportionally may in fact be following a procedure without understanding it.
- Understand methods for developing students' proportional reasoning.
