Graph Makeover: It’s about time

Think back to a time when you encountered a “real world” graph in a math class. What was on the horizontal axis?

Probably TIME.

Graphs represent relationships between two things. When working with graphs, it is important for students to form and interpret relationships between TWO things that can change. Yet, if one of those things is passing time, students might be thinking about only ONE thing changing.

Want to provide students opportunities to think about TWO things that can change?

Have students interpret graphs that represent two changing lengths.

It’s about time that students have opportunities to encounter “real world” graphs representing things other than time.



Use Tech to Broaden Students’ Opportunities for Math Reasoning

Subtitle: The reason I’m giving this talk at #NCTM2017.

Think of technology as “playground equipment” that teachers can use to create online “learning playgrounds” for students.

By using different kinds of equipment, we can broaden students’ opportunities to engage in mathematical reasoning.
