Hi @theresacook,
That does sound helpful. We currently don’t have a centralized collection of student work, but if there’s a specific lesson for which you would especially like to see student work, I recommend posting a request in that lesson.
Another teacher has made such a request for the “Circle Triangle Square” lesson (1.4) and I dug up some old student work and uploaded it: 1.4 Number systems - Circles, Triangles, Squares
