Lesson 17: Parameters and Graphs
About this lesson
In preparation for the associated Algebra 1 lesson, this lesson is focused on generating and practicing informal language used to describe transformations of a graph. Students have opportunities to describe changes to a graph in a way that makes sense for them, and opportunities to make their language . more precise (MP6). This will enable students to have this language at the ready. They also spend more time drawing connections between transformed graphs and their equations.
Lesson overview
- 17.1 Warm-up: Which One Doesn’t Belong: Triangles (10 minutes)
- 17.2 Activity: Describe the Change (20 minutes)
- 17.3 Activity: Select a Function (10 minutes)
Learning goals:
- Analyze how a change in each parameter of the function changes the graph.
- Graph quadratic functions given in vertex form.
Learning goals (student facing):
- Let’s talk about moving graphs around the plane.
Required materials:
- Graphing technology
Standards:
- This lesson builds on the standard: CCSS.8.G.AMS.8.GMO.8.GM.A
- This lesson builds towards the standard: CCSS.HSF-BF.B.3MS.F-BF.3MO.A1.BF.A.1
