Lesson 7: Observing More Patterns in Scatter Plots

In this lesson, students see non-linear associations for the first time and do a card sort to distinguish linear and non-linear associations. They visually identify clusters in data. Students will not study non-linear associations or clustering using quantitative tools; instead they will rely on visual patterns in scatter plots (MP7). 

Lesson overview

  • 7.1 Warm-up: Notice and Wonder: Nonlinear Scatter Plot (5 minutes)
  • 7.2 Activity: Scatter Plot City (20 minutes)
  • 7.3 Activity: Clustering (10 minutes)
  • Lesson Synthesis
  • 7.4 Cool-down: Make Your Own Scatter Plot (5 minutes)

Learning goals:

  • Categorize data sets, and describe (orally) the properties used to create categories.
  • Describe (orally) features of data on scatter plots, including “linear” and “nonlinear association” and “clustering” using informal language.
  • Explain (orally) what might cause a nonlinear association or clustering of data points in context.

Learning goals (student facing):

  • Let's look for other patterns in data.

Learning targets (student facing):

  • I can pick out clusters in data from a scatter plot.
  • I can use a scatter plot to decide if two variables have a linear association.

Required materials:

  • pre-printed cards, cut from copies of the blackline master

Required preparation:

  • Print and cut up cards from the Scatter Plot City blackline master.
  • Prepare 1 set of cards for every student.

Glossary:

  • Access the complete Grade 8 glossary.
