Quiz/Questions to teach NFHS rules to HS Players?

[MECU]

One of the things I learned this past season, my first as a real HS coach, is that the kids don't really know the rules (nor do the refs or coaches as well as they should). So, for next season, I would like to give my kids a take-home "quiz" or "worksheet" that they have to fill out that would require them to at least write the right answer, hopefully and ask questions if they don't know. No grades and they can work together, but just so they know certain things that we assume to be fundamental, like:

A player in motion can not be going forward at the time of the snap.
There must be 7 players on the line of scrimmage. The two on the end must be eligible numbers. If there is a TE on the right side, then the WR must not be on the LOS otherwise the TE is ineligible.

But also cover other things, like what personal-fouls are and the penalty yards for certain types of penalties.

I'll cover other things like "name this formation" and stuff as well.

Has anyone done anything like this? Does anyone have any questions or quizzes they have done in before they could send me? Was this beneficial to your kids?
