by Texas Instruments


  • Students will use symbols to represent unknowns and variables.
  • Students will look for patterns and represent generalizations.
  • Students will represent relationships among quantities using visual models, tables, graphs, and words.


  • function
  • growth rate
  • constant rate
  • linear function

About the Lesson

This lesson involves using pattern growth to construct functions.
As a result, students will:

  • Explore growing tile patterns pictorially, graphically and in tabular form.
  • Examine the relationship between the stage number and the number of tiles.
  • Determine a rule for the number of tiles as a function of the stage number.
