The Line Game 2.0

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?

Click here to read the post about the game.

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.

Teaching With Desmos Activities

I've never really considered writing a blog post about Desmos.com because I figured people would just go to their site to learn.  But it might be beneficial to see how other teachers are using it.


Yesterday I gave my Algebra 1 students a test on graphing with slope-intercept.  The averages of the classes were 75% for the one class and 65% for the other class.  Clearly, they weren't ready for the test.  I decided that this topic is too important to ignore so we are re-learning and re-assessing on the topic.

This is a link to the desmos activity.  

**Note**  Be prepared for inappropriate drawings on the activity.  Period 3 thought it would be funny to draw a penis for all to see. ((sigh))
