Make Connections

Performance Task

Ways of Thinking: Make Connections

Take notes your classmates’ approaches to revising the Self Check problem and applying what they learned to solve a similar problem.


As your classmates present, ask questions such as:

  • Why didn't you reverse the direction of the inequality sign?
  • Why did you use a closed circle on your number line?
  • How do you know that your number line shows all the solutions to the inequality?
  • Are all the numbers on the number line solutions to the problem? Why or why not?
