there are no grades

Throughout my elementary years, I was in a pull-out class that was largely project-based. I remember some of the projects—develop a theme and a menu for a fictional restaurant, track the Iditarod, invent something (!!)—but I mostly remember my teachers invariably saying, “I don’t really want to show you an example, because I don’t want you to get locked into just one type of idea.” 

But, we’d argue, how will we know how to do it right if we don’t see what “right” looks like? 

“I want to see what you come up with.”
 

We never got any grades in that class.
