Value of Absolute Value

Kids just can’t seem to figure out absolute value. Pat writes,

“I’ve posted a mistake I see ALL THE TIME from my students when working on Absolute Value Equations. Looking for any advice on how other teachers are handling this issue. Thanks!”

Incidentally, I think that there’s a very good argument for this sort of thing being struck from the curriculum in its entirety. It’s entirely isolated in the curriculum, unconnected to anything else.

Thanks to Pat John for the submission!

What are these kids struggling with? What are they getting right? Are there interesting differences between the three different students whose work is shown?
