So I just assumed everyone knew this, but just in case, this is a nifty way for students to quickly send you what they’ve done on any program such as Geogebra or Desmos: just use the “Print Screen Button”! It actually works really well–it copies something onto the invisible computer clipboard and if you open a Word document and “Paste”, the entire screen will show up there! Here are some examples of my students sending me things they were actually excited (and proud) to do. I just assumed that my students could “see” reflections, even across the y=x axis. Not true!! So yeah, they pasted 4 or 5 of these in a Word document and e-mailed it to me (most students could do this at school during lunch or their break–I try to be sensitive toward those students without internet/computers at home). And yes, I gave them a handful of Participation Points to sweeten the deal.
