ACTS is what the teacher will do and ASKS is how the teacher will facilitate.

ACTS ASKS
  1. Give students a problem solving scenario and have them think about how they would solve the problem.
  2. Create a personal connection by allowing students to share a time when they solved a problem.
  3. Explain how motion is needed to move the object.
  4. Introduce the vocabulary term force.
  5. Demonstrate how the 123 Robot can push or pull an object.
  6. Explain how motion and force works with the 123 Robot by pushing or pulling an object.
  7. Demonstrate how to code the 123 Robot to push a paper ball.
  8. Demonstrate how the 123 Robot can pull a pencil.
  9. Demonstrate how to 123 Robot can push or pull another object in the classroom.
  1. There are a lot of kids on the playground at recess. You are trying to go on the swings, how do you get there?
  2. Can you think of a time when you had to solve a problem? What did you do to solve the problem?
  3. How can I move this book? Have you ever pushed a cart?
  4. Force is all around us, such as pushing or pulling a chair or even a door.
  5. How is the 123 Robot pushing the ball of paper?
  6. Have you seen a machine like 123 Robot push or pull an object before? Give some examples.
  7. What is the 123 Robot doing that relates to motion and force? How does pushing the paper ball relate to motion?
  8. What is the 123 Robot doing that relates to motion and force? How does pulling the pencil relate to force?
  9. How does motion and force affect the 123 Robot?

Engage

  1. InstructInstruct students how motion and force relates to our everyday lives.
    1. Ask students, “How can I move this book?” Explain how motion is needed to move the object.
    2. Ask students, “Have you ever pushed a cart?” Explain how force is all around us. Things hanging, sitting, balancing, moving, and spinning are all using some kind of force. Forces come in different forms and they all result in something.
  2. DistributeDistribute materials for motion demonstration by the teacher.
    1. Ask students what will happen if 123 Robot is programmed to move forward in front of a ball of paper.
    2. Ask students how they have seen motion and force in real life.
  3. FacilitateFacilitate students' understanding of force by demonstrating with a 123 Robot.
    1. Demonstrate how the 123 Robot can push or pull an object.
    2. Explain how motion and force works with 123 Robot.
  4. OfferOffer ways how 123 Robot could get over a large bridge.
    1. For differentiation, if students are still confused about how force works with pushing and pulling, allow students to go into pairs and see how motion and force affect the 123 Robot. 
    2. Allow students to use various objects to test a push or pull on 123 Robot.

Teacher Troubleshooting

Facilitation Strategies

  • Allow students to use materials that they feel invested in and choose themselves. 
  • Distribute materials for the bridge challenge by allowing teams a certain number of supplies to allow each team a fair chance to gather materials.
  • Explicitly talk about failure and how to react.
    • Allow students time to model if needed what being a good team member looks like. 
    • Give students the ability to see failure as part of the iterative process. 
    • Encourage students to try their best even after trying and trying again to successfully build the bridge.
