Quantitative Reasoning Activity

Experiencing the mathematical practices as adult learners

A brief activity to rekindle our own math practices

Mathematical Task: Interpret graphical information

5 minutes: Individual (think)

  • What is the topic of the “Mistake on a plane” graph?
  • What to the horizontal and vertical axis represent?
  • What are some observations ¬†or inferences you can make based on the graphs?

10 minutes: Partners

  • Discuss your answers to the three questions for the graph on this page
  • Work through the same three questions for the “there will be blood” graph

10 minutes: Groups of 4

  • Share your insights on both graphs
  • For each graph, write at least one question that requires a numerical response
  • Identify one or more mathematical practices that you employed.
