How long until they collide?

Show the beginning of the video. Stop the video at about 39 seconds. Take guesses from students.

After students have worked for a while and you have traveled around and selected some students and their work to share, show the rest of the video. This is also a great opportunity to talk about the dangers of distracted driving.

    The video does not work anymore. It says the video is “private”. Does anybody know where I can find the video?

      That video is now private, we put up a new, shorter version of the video that we found online.
