My students really loved your mystery box in Math Club today. We figured out the four colored boxes and the relationship between the number on the left and the green dots. However, we were a bit puzzled by how the right hand number affected the location of the green dots. Our conjecture was just a little bit off when we looked at the coordinates of the points. Do you have an answer key that I could share with my students? My email is janetaylor@covenantchristian.org

Here's mine: https://teacher.desmos.com/activitybuilder/custom/62bcc3a938d4c027165ecc53

It seems like it should have been easier to do the previous attempts part, and maybe it is. This was a first try.

Here is mine. Thinking about how to combine this with collaborative Vertical Whiteboards that I plan to implement next year... https://teacher.desmos.com/activitybuilder/custom/62b8634cf76f9ac504ef893c

Ok, here's my first shot. The problem is I don't actually know what my mystery box is doing! I want to do (input+5)*(input-5) so if input=1, then it would be 6 * (-4) = -24. But as you can see, that's not what is happening! I feel like I missing something obvious.... Help? https://teacher.desmos.com/activitybuilder/custom/62b34a3454427b79cc987b9a

Edit the simpleFunction: you have "{" and "}" as grouping symbols instead of "(" and ")"

So the { } do nothing in a numeric expression. Got it.
