Slapdash proof of concept video I threw together demonstrating classroom workflow using an iPad mini and the Procreate app to color linework drawn with pencil and pen on paper.
I've used this app for painting and coloring on my first generation iPad in the past and was pleasantly surprised that the experience on the iPad mini worked out nicely even with the decreased screen real estate. In fact, I eventually found the overall smaller size of the mini to be preferable to the larger iPad when working on a drawing over an extended period. I can definitely see the mini working out just fine in an art classroom deployment.
