Where to Start? (14 to 18-year-olds)

Hello, Chess.com community. 

So, I've started a chess club at my high school (I'm a matric, so I have some authority, but I'm not an actual teacher), and, well, they're not exactly very good players. Some cannot play, but most can. I expected the club to just be casual play, but the majority of them are actually very interested in improving their games and eventually attending tournaments. I subsequently actually offered to teach them a thing or two (I'm no grandmaster [yet, if I may be pretentious], but I know what I'm doing). I also spoke to the president of the province's chess federation, and he's interested in organising a fundraising (our equipment sucks) school chess tournament once my players are a little bit more comfortable in front of the board. So, this is really happening. I'm thinking one lesson after school per week, and two practice sessions during lunch hours a week (maybe a tournament bi-monthly or something). Only issue is, I don't know where to start, and I'm sorry if this is a really commonly asked question on these forums (most threads seem to be about teaching young'ins ages 4-10). Here are my ideas thus far:

First week: How to play (just basic moves, leaving out castling and en passent for now), goal of the game. 

Second week: More advanced moves (castling, en passent), algebraic notation.

Third week: Intro to the Giuoco Piano (I chose this opening because it was the first I and most people I know learned. I don't play it any more, though). 

Fourth week: Intro to tactics (pins, forks, discovery attacks, blocks, capturing defenders, king harrassment, etc.).

Fifth week: Seeing advantages/disadvantages (space advantage, king safety, pieces' point values, etc.).

Sixth week: Looking at the Giuoco Piano again, this time more in depth with the new knowledge learned. 

Weeks after that I'll figure out later, I've got time. 

Thoughts? Anything I should change/move/add? I'm sure I've missed a bunch. Also, any additional tips? 

Thanks in advance! 

Cheers,

I wouldn't tell anything about opening in the 3rd week, once they've understood the rules and the basic mates (you forgot about them!! ), you should start with tactics! (they can understand what advantage really means, so they'll hardly understand the ideas behind the Giocco Piano or any other opening.

So, two more weeks only with tactics, and then, we start with strategical subjects (piece activity and central control advantage in the middlegame mainly) Once they know about this, you can start introducing them to practical endgaming (rook vs rook or rook + kinght vs rook + bishop with pawns) Only now you can talk about the opening, but about the opening in general and not a single line (they're games would turn bored and repetitive. let their imagination work!) My trainer is considered one of the best in my country and he NEVER talked me about opening until I was 1800 ELO!

I hope my advice would be helpful! Good luck to all them (you)!

PS: I was nearly forgetting, I think you have to introduce them soon another key part of chess (maybe not in the first 6 weeks, but don't let it be too late) I'm talking about.. TIME! It's good for them to know the clock and the time administration as soon as possible. Of course, don't make them play Blitz, but 10-15 minutes games are OK for the very beginners!

Basic checkmates seem a good place to start. Winning with 2 queens vs king, 2 rooks, 1 queen, 1 rook.

If you can't win king and queen vs king, then nothing else really matters yet.

Don't teach the Giuoco Piano everybody knows it, instead try the Ruy Lopez or the Scotch.

Let's just do not listen to this guy. We are talking about BEGINNERS!
