    1 - Getting Started ~3 mins

    Illustration for Getting StartedLook at our little floor robot. Can we send it all the way to the star?

    What do you think we need to tell it first?

    2 - Moves in Order ~2 mins

    We put moves in order to send the robot to the star.

    How will we know if our robot got it right?

    3 - Watch the Robot Go ~6 mins

    Watch carefully. I will put some moves in order and send the robot toward the star.

    Where do you think it will stop?

    4 - Plan the Steps Together ~5 mins

    Let's plan the steps to the star on the board before we touch the real robot.

    Which moves will get our robot to the star? Call out forward, turn left or turn right.

    Send the robot to the star

    5 - Send Your Robot to the Target ~10 mins

    Illustration for Send your robot to the targetWe have one mat, so one group at a time comes up to it while everyone else works from the carpet. When it is your group's turn, you lay the arrow cards in order first and then guess where the robot will stop: on the star, short of it, or past it.

    If you are on the carpet, you have a job too, because you guess along with them and help spot the step that sent the robot the wrong way.

    Missing the star is not a problem, and it is where the good thinking happens: the group at the mat changes one card and, if there is time, sends the robot off again.
