  • What did you need to figure out in Play Part 2 to collect and sort the Disks? What strategies did your group use to solve the challenge? 
  • How did the [If then] block use the data from the Eye Sensor to sort the Disks to the right location? 
  • What block(s) control the Eye Sensor in our projects?
  • What block(s) have the Code Base make a decision? What is this decision based on—what is the condition?


  • Why might you want to control a robot with an eye sensor in a real world situation?
  • What other ways could you use the Eye Sensor to help the Code Base accomplish a task?
  • If the Disk started in a different location, would your project still work? Why or why not? What would you have to change?


  • How did your group do following your role responsibilities? Do you have a ‘favorite’ job or role? Why?
  • What is one way that you were a problem solver in your group to complete the challenge?
  • If a new student joined your group, how would you explain how to code the Eye Sensor on the Code Base to sort a Disk based on its color?
