I teach these basic transformations as part of my middle school math classes, and I was completely loss as to why they didn’t include a reflection, but then I realized a reflection wouldn’t be that interesting because it could be indistinguishable from a translation.

I was at a loss too as to where they source the “moist common” when skewing is also extremely common

Scaling, in general, is the least common middle school transformation covered by state curriculum as far as depth of knowledge is concerned, at least where I’ve taught. Students just aren’t ready at that age to calculate something as sophisticated as the scale factor contributing to an objects loss of size.

I think the students are ready and quite capable of such sophistication. They’re just too distracted with sharing memes.
