Ways of Thinking: Make Connections

Take notes about your classmates’ explanations of the mistakes in reasoning about percents that people make.


As your classmates present, ask questions such as:

  • How did you decide what numbers to use in your example?
  • Can you try another example to see if you get the same result?
  • Can you think of another situation in which a person might make this type of mistake?
  • Do you think your explanation is convincing? How could you make it better?
