People solve problems in different ways. Let’s examine a variety of possible approaches that may be similar to or different from your own.

Step 1: Consider alternative solution methods

As you view the document below, take a look at the solution strategies and consider these questions:

Which method most closely resembles how you thought about the problem?
Which of these methods do you think your students might use?

Step 2: Consider a mathematician’s perspective

This task analysis provides a mathematician’s perspective on the mathematics of the Pool Border task. You may find the mathematical ideas that are presented helpful as you watch the video in the next activity. You may also want to refer back to this analysis as you continue to explore the task and video throughout the module.
