Show the beginning of the video. Stop the video at about 39 seconds. Take guesses from students.
Have kids work individually on the problem for a few minutes or more, followed by partner work. You might project the image below for students so they have a clean view of the problem.
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.
