I love playing The Line Game with my students, but there is one problem: not all students can easily see the graphs that are projected. Then after face-palming myself, I created a Desmos activity. Why did it take me so long to figure this out?

Now, instead of the students squinting to see the graph on my TV, they can see the graph on their computer screens.
Here is a link to the activity.
You will want to click the option with "Teacher Pacing" to make sure they are looking at the correct graph and not cheating by looking ahead.
