One art teacher at a middle school in Wyoming has given us some wonderful insight into exactly how it is that teachers can sometimes inspire sparks of creativity in their students. Reddit user Nate100100 shared a series of images showing the chalkboard drawings he draws for his students to show him how much can be done with the simplest materials.

A lot of responses when I first started were along the lines of ‘Did you draw that?!?’ I would hope their art teacher knows how to art,“ writes “Nate.” He sometimes uses the drawings to illustrate artistic concepts like shading.

Eventually, the time comes to erase his art, but this teacher doesn’t mind; “There is something kind of nice about knowing that it will be erased. I don’t fret over supplies, paper, whether or not I should keep it… Kids see it and then it disappears.
