Teachers already seem overworked. Wouldn’t they just invent a new magic number, maybe “1”?

  101 would be a relatively safe number to use as a placeholder. Since these people aren't programmers, trying to use NULL or NaN or -1 will probably backfire.

    Sentry values are a nope. Have the assignment have a is_published check box / flag. An option to select all as published and the ability to toggle/select individual's assignments as published.

    No, there could be extra credit

  It wouldn’t stop a 0 from being entered as a grade — just not push that notification. This would actually makes teaching easier, as they can use a 0 as a placeholder without having to decide about accidentally pushing a notification. I don’t think the teacher’s goal is to cause a panic with a transient 0 that’s later replaced — so I don’t see why they’d stop using something that better accomplished their goals.
