By the way, I just notices that the "Previous math exercises" category is beginning to show. I have noticed from my experience in the 3rd grade mission that some (but not all) of these are previous simply because of a rename. As I complete overhauling a math mission, the ones that remain in this category will eventually be truly previous (as in they are not used anymore).
