I am the Chess Club Coach at my High School. Any Advice?

I am a building substitute teacher in a working class school in Michigan. My wife teaches french and history at the same school, and we started up a table-top gaming club last year to provide our kids something safe, fun, and social to do after school. It was a roaring success on the back mostly of Dungeons and Dragons.

This year, the freshman class came in with a lot of chess enthuasists, so what we did is spin off a dedicated chess day on a diferent night. (Monday is Chess day, Friday is open game table top club).

I took up the role of coach because despite being a weak player (current 860; high 1250) I love the game, and the students wanted me to head this up. At the start it was easy. I taught them opening principles, fundamental end games, and basic tactics. I taught them how to run clocks and how to notate their games algebriacly. 
The next thing I am going to show them is how to come up with an opening repitore (just the basic moves, a response to e4, d4, and to put pawns in the middle against non-classical stuff). After that I am not sure where to go, so I am looking for suggestions.

Also I'd like clarity on something. My understanding of the rules is this:
*When your clock is running you own the board, and when your opponents clock is running they own the board. 
*You must move, capture, and hit the clock all with the same hand-no hovering the clock.
*Notation; Make your move, hit the clock, and then notate during opponents move?
The thing is I am a grown man and I still sometimes mess this up. Are high school kids really expected to have this down super strictly? How are minor infractions handled in the tournament setting?
Thank you all in advance for your time and input. This oppourtunity means a lot to me, and I want to prepare these students as well as I possibly can.

did you really need to notate the best players will remember entire move combos and then write it down do you guys really need to do that can you just record the games

also this is just my opinion but i think the other player should hit the clock how are you supposed to not lose precious time at the end just my opinion

The way that I am teaching them is in accordance with FIDE Handbook. 
Source: https://www.fide.com/FIDE/handbook/LawsOfChess.pdf

"6.7 a. During the game each player, having made his move on the chessboard, shall stop
his own clock and start his opponent’s clock. A player must always be allowed to
stop his clock. His move is not considered to have been completed until he has done
so, unless the move that was made ends the game."

"8.1 In the course of play each player is required to record his own moves and those of his
opponent in the correct manner, move after move, as clearly and legibily as possible, in
the algebraic notation (See Appendix C), on the scoresheet prescribed for the
competition.
It is forbidden to write the moves in advance, unless the player is claiming a draw
according to Article 9.2, or 9.3 or adjourning a game according to the Guidelines of
Adjourned Games point 1.a.
A player may reply to his opponent’s move before recording it, if he so wishes. He must
record his previous move before making another.
Both players must record the offer of a draw on the scoresheet. (See Appendix C.13"
Now my understanding is that diferent tournament organizers might be lenient, but my thought is that if I can get my students to play up to FIDE standards they will be surely prepared for anything less intense.

i dont think the notation is necessary chess clubs dont do it and they have masters why should you

ah i guess because these youtube clubs record their game i just dont think it should be necessary

You might discover something of interest here.....not about the rules per se, but about playing the game.....

(by the way, it's spelled repertoire)

bro ur 800 ur just gonna teach them how to hang pieces

Bro, the alternative is they have no chess club bro. Bro why you hating? Bro come back with some helpful advice bro. Bro if you aint got anything decent to say don't say nothing bro. Got it bro?

teach them chess wrong so you are forever the best chess player in the school

I'm also teaching scholastic chess. The Chess Steps curriculum is a pretty good place to start. Just get Steps 1&2, you won't need anything beyond that. Typically I start with a short lesson (just a few minutes long) followed by a worksheet (one page from a Steps book). Then I let the kids play for the rest of the time, while I observe and drop occasional helpful tips.
Find out about scholastic tournaments in your area. Most of your kids won't ever play in one, but they're a nice opportunity for the kids who take chess more seriously.
One of the first lessons I teach is how to checkmate with king & queen. That's my personal criterion for whether a kid is ready to play in a tournament. You'd be surprised at how many kids in scholastic tournaments can't do it.
Above all, remember that the kids are there to have fun, and that means playing chess. Not listening to someone talk about it. Keep the lessons short.

If there are some good chess players among them, I think also have the kids learn from each other too, like have a group of kids come up with possible variations/moves in the opening after a certain amount of moves to make up their own theory moves and then have it check with real-world data. 

Also, have some more knowledgeable chess kids teach the others too. This helps those who want to keep on learning learn more and also lessens the burden on you a bit depending on how many you are teaching.
However just like Bramblyspam said, if they're there to have fun then let them have fun, but if there are any who want to learn more chess then teach them, stronger chess kids teach others too, possibly even recruit some chess kids to become chess coaches for beginner players, or have them work together to solve a puzzle, or come up with variations on the board to see which is the best move (sort of like vote chess?)

Sounds like I am on the right track, as I was already structuring it in the ways mentioned above. I still appreciate everyone's perspectives and ideas.

I assume you're getting whipped by the kids. Just tell them to search for lessons online.

The spelling in the original post doesn't pass muster either. What is a "repitore"? Maybe the French mistress can help with that one (among several).

@OP
It may be that there is genuine interest in chess at your school or not. Your own strength is not an issue IMO if you love the game. By the same token it is not important for you to even carry the notion to your students that you are a fabulous player. I suggest relaxing and follow them rather than trying to lead. Some will do their own studying and bring it to the club.

My soapbox:
I was once a teacher — England — but found the system is not supportive of activities directly related to the examination factory. There is a correlation with wealth in the locality as well as to which schools participate in chess. The demise of many of the grammar schools levelled the playing field down for the majority working class population. My local club has a diminishing number of grammar school pupils who are now dying off. Chess in England was becoming classless over the course of the twentieth century. Now it is becoming a pastime for the wealthy middle classes much more as evening chess gives way to 4NCL hotel weekend chess. Chess coaching and participation — involving hotels and travel — at an early age makes a big difference. There is chess talent, of course there is, but the greater vector of achievement is environment.

Ur gonna get a bunch of 14-1800s that want u to know they’re 14-1800s that’s how the forums go
