Using Problem Strings to Develop Proportional Reasoning

Technology: TI-84 Plus family, TI-Nspire™ Technology
Topic: Teaching Strategies
Speakers: Pam Harris

How can you help your students to reason about proportional situations, including those with unit and non-unit rates?

During the webinar, the presenter uses the instructional routine of "Problem Strings" to demonstrate how to help students construct multiplicative and proportional reasoning.

Explore the power of TI technology to:

  • Create scatter plots of proportional data
  • Graph functions that model the data
  • Examine rates of change and the connections to the data and the functions

The presenter utilizes both TI-84 Plus CE and TI-Nspire™ graphing calculators during the webinar.
