  • Facilitate the students completing a gallery walk to observe, and cheer on their peers.
    • Ask 1-2 teams to walk around and observe their peers complete the trailer challenge.
    • Ask these teams to observe, offer suggestions or give positive comments to the team.
    • After the two teams finish, allow two more teams to observe, offer suggestions, or give positive comments.
    • Allow students to continue to rotate giving each team 20-30 seconds.

Digital Documentation

  • Use video to record the process during Play Part 1 when the teams are completing the obstacle challenge. 
  • Use video, audio, or pictures to record the process during Play Part 2 when teams complete the pull challenge by constructing a trailer and coding their 123 Robot to complete the challenge.

Student-Driven Visible Thinking

  • In Play Part 1, students show their ability to create a sequence of code on 123 Robot to avoid a self-engineered obstacle. Students are visually creating an authentic problem and then solving that same problem. 
  • In Play Part 2, students continue to code sequences for 123 Robot to now pull a trailer and avoid the same self-engineered obstacle. Students’ thinking is visible through the coding and problem solving in this activity.

Metacognition-Reflecting Together

  • Observing Prompt
    • How did pulling a trailer make a difference in your challenge? Were you successful? Why or why not?
  • Predicting Prompt
    • How do you think real self-driving cars work  in the real world?
  • Collaborating Prompt
    • How did your team work well together? What helped your team?
