Instructional Ideas

  • Use this activity to introduce exponential decay after a lesson on exponential growth
Classroom Considerations

  • The task assumes that students can use a graphing calculator to create a scatter plot
  • A large volume of materials is necessary
Pros

  • A student data collection sheet is included with the resource
Cons

  • Inconsistent use of language, such as referring to each iteration as a "throw" or as a "toss"
  • Data collection table indicates 200 as original number of objects in the cup, but this can be impractical for some of the objects (such as number cubes)
