OM DENNE EPISODE
Why ratios are about how quantities move together
This episode launches our Connecting Math series by reframing ratios as relationships rather than calculations. Instead of treating ratios as fractions or procedures to memorize, we explore how ratios describe how two quantities vary together and why that way of thinking must be developed over time.
Building on December’s focus on Seeing Math and January’s work around Understanding Math, this episode connects geometric reasoning and number sense to proportional thinking. We unpack the progression from counting to additive, multiplicative, and proportional reasoning, and examine why students struggle when instruction jumps too quickly to rules.
You’ll hear how representations like number lines, tape diagrams, and arrays help students visualize relationships, how the Standards for Mathematical Practice reveal student thinking, and why carefully guided instruction is essential for developing mathematical reasoning.
This episode sets the foundation for everything that follows in ratios, proportions, slope, and functions by focusing on the thinking students need, not just the answers they produce.
Listener Reflection Questions
- When students in your classroom struggle with ratios, what evidence do you see about their reasoning, not just their accuracy?
- How often do students have opportunities to visualize and explain how two quantities change together before being asked to calculate?
- Which representations are you currently using to help students connect geometry, number sense, and proportional reasoning, and where might those connections be made more explicit?
