Title: Gallery Walk
Description:
In this lesson, one of a multipart unit from Illuminations, students view the work of other students in the class and explain their own work. Students move from graph to graph during this time and, without any talking, view the work of their classmates.

**Under the Read Me it describes the following restrictions:
"Usage Restrictions: Plotting graphs is computationally intensive. To limit the burden on the internet service provider for Karl's Calculus Tutor, you will be restricted from plotting another graph after you've plotted one for 3 minutes after plotting a small, 5 minutes after plotting a medium, 12 minutes after plotting a large, 20 minutes after plotting an extra large, and 40 minutes after plotting a huge. Tiny plots incur no delay, so you can use them to preview what the larger plot will look like. So enter your fields carefully before clicking the Plot Now button. Note that if you get an error when you attempt to plot, you will not be delayed in trying again."
