Four 4s (Class competition version)

Desmos version of the classic problem Four 4s with a class leader board. One use idea: Allow students to work on this in their free time, over the course of, say, a week. Winner at the end of the week wins. Here is a link to the class COLLABORATION VERSION (everyone still has their own board but the activity is about working together, and doesn't broadcast points): https://teacher.desmos.com/activitybuilder/custom/5eb3af78c7b0a70c6400dd1a Here are links to all the previous iterations of this activity (including french translation courtesy of Frédéric Ouellet): https://teacher.desmos.com/collection/5ec2c10e6670317f6c614ff5 If you liked this activity and found it useful, I would love to hear about it on twitter! @KenClarkson3
