user19877: I have been running the chess club at the local high school, which I graduated from 40 years ago. As part of it, I have been giving free lessons.
I have had several problems, and I am looking for suggestions on how to overcome them.

There are very different levels of strength. We had a core group, but recently, an entire sports team started showing up. They decided to stay, and play, while they wait for their practice to start. They are much weaker than the rest, but they still enjoy it. Interest in the lessons within this group is mixed.
Some kids miss meetings, so when they come back, they have missed a lesson. If this were an actual academic class, I could have them make it up, but that does not work so well when you are trying to keep it fun. That said, they get behind, and I don't want to move on without them.
New kids show up, and have missed everything.
Lastly, the time is limited to about 1:45 each Friday.

I have some ideas, but I thought I would get some from you before I mention them. The core group really has some interest, and have been enjoying learning more about the game. We might like to eventually form a team.

user20776: Chess website at school summarizing lessons along with other school related chess info.   
Point to chess websites for more that they can use especially if they missed.  
Advanced kids play while you help newer ones catch up.  What do you do with that much time anyway?  They want to play not hear lectures.
Go to each game and give pointers as appropriate to specific players.
Rotate openings, tactics, mates, end games,  other topics.  
Chess is not so much  like math where everything builds so neatly on the other stiff so you do not really get behind except in the sense that you have already done more and so have moved forward.  
Have a range of problems from easy to hard each time,  so that everybody can do some and learn some each session.  
End the semester or year with a tournament.  Swiss style.  Analyze the games and see what they need to learn most next semester/year.

user19877: I decided that I would break the class into two groups.
I will teach the real beginners during the first half of the club's time, and the slightly more advanced players during the second half of the club's time.
In addition, I will be printing out materials that I deem relevant, so if kids miss a lesson, they can take it home with them.
I simply do not really have the time to do more, but if I did, then I would probably like the idea of recording the sessions YouTube-style, and posting them.

user20854: Relate the moves for chess to the strategy of the sport they play as I am sure a  really good analogy can be found like setting picks for basketball or football has endless comparisons for forks skewers and pins It also may help them in there sport to visualize better from chess tactics so win win. If they are weaker players than these concepts will represent the largest progression to there game anyway. good luck

user9423: You could record your lessons for class consumption. This would be useful for students who miss lessons. Please make sure if it's legal to record group lessons in your school though.
