Teachers, save “Perimeter Explain Everything” to assign it to your class.

1. Solve the problem and check your work. 2. Use the to record yourself explaining what you did AND WHY those are the steps. Do not record yourself as you work. I recommend using the arrows to help point to specific steps as you explain your thinking. 3. Click the green to end the recording at the end of each page. Your explanation should be no more than 30 seconds long. 4. Repeat these steps for all of the problems. Each page should be a separate, full-page recording of you explaining your work.
