Lesson 19

Adjusting Windows

These materials, when encountered before Algebra 1, Unit 5, Lesson 19 support success in that lesson.

Lesson Narrative

The associated Algebra 1 lesson, which is about contrasting linear and exponential growth, depends on students understanding how a graph might look different if a different graphing window is used. The purpose of this lesson is to give them time to experiment with setting some different graphing windows. The warm-up is used to revisit how to use their graphing technology to change the graphing window. In the first activity, students change the graphing window to match different, given versions of a graph, and then consider why people with different motivations might choose different versions of a graph. In the last activity, students choose a graphing window so that the same given function can tell a different story. Choosing a specific graphing window for a specific purpose is an aspect of modeling with mathematics (MP4).

Learning Goals

Teacher Facing

  • Prepare to graph functions with technology with understanding of different graphing windows.

Student Facing

  • Let’s make a graph of the same function look different.

Required Materials

Required Preparation

If possible, each student should have access to their own graphing technology device.
