Reflection: Intrinsic Motivation Cat Island (Day 2 of 2): Cats can’t add but they do multiply! - Section 1: Revisit Cat Island


I had originally planned for this lesson to be introduced before a week long break and then to be finished on the first day back. My reason for planning it like this was so that I could really focus on giving good feedback to students over that week. Somewhere between midterms, shortened bell schedules, and assemblies I lost this half day. So we ended up working through this lesson in one 50 minute period. It was still great. I really liked this lesson!

Here is the breakdown of how I allotted the one 50-minute class period:

  • 5 minutes: Introduce Cat Island
  • 10 minutes: Students Solve Independently (quiet work time)
  • 10 minutes: Present 3 students’ work (provided in this lesson) and talk about the assumptions each student made and what we liked or didn’t like about their work
  • 25 minutes: Revise/finalize answers in teams

Also, here a few struggles and successes that my classes had with this activity: Cat Island, video reflection, our successes and struggles

Unit 4: Exponential Functions and Equations
Lesson 2 of 14

Objective: SWBAT investigate an exponentially increasing sequence and make sensible estimates and assumptions based on this sequence.

Big Idea: Looking at the life cycle of cats, students use exponential models to see how quickly populations can grow in the real world.
