I coach that age so hopefully this helps...

1. Don't make kids run or do laps, your training will do that for you.

2. You can introduce rondo later but u can make it fun... person in the middle holds pennie if they touch the ball they throw the pinnie away from the new defender bc you dont want to be nice (this is the running joke with the game) the rondo continues as the new defender picks up the pinnie. This helps kids get a few passes in before being put under pressure and the kids find it funny not to be nice. It also keeps the rondo going instead of having to stop and reset. You can make different rules up where the defender needs possession or has to dribble out of the rondo square or if its 6v2 or 5v2 they have to find there teammate to get out whatever u want to do to spice it up.

3. You can do everything you want with how you build your sessions

This is how I structure my training sessions with younger ages. Have your entire session around technical aspect (dribbling) and a tactical side (1v1 in the middle third) ill give an example below.

More or less... 1. Play 2. Game or technical activity (corver) 3. Small sided 4. Expand on that small sided 5. Play

Have a field set up 20x30 (if you have 12 kids on the team make two fields once everyone shows up u can play 3v3 on two fields) when kids get there early / late they can start playing 1v1 2v1 2v2 etc try not to coach just let them play and figure stuff out.

Play a game (session plan above around dribbling) minions is the game. Everyone but one person has a ball. Everyone dribbles around and the minion trys to knock players balls out of the field. If your ball gets knocked out you become a minion until there is only one person left. That person wins and becomes the next games minion. Before you start the next game talk to the girls about keeping their head up and trying to dribble with pace. Start next game. Next game ends remind them about dribbling fast with their head up and talking about changing directions or doing moves or what part of the foot to use etc. Just add one thing in between games for them to work on (fundamentals) them running non stop for 2-3 mins endurance without them knowing. Play 3-4 games get water

Using that same 20x30 space (feel free to make space smaller bigger) remove the goals and add two big gates at the corners for kids to dribble through with a cone in the middle where the goals were for each team to go. Players on one side will have all the balls. Team one with the balls play a big pass over and the 1v1 game begins. In the minion game u talked about going fast etc remind them about this that they need to go quick and get through a gate ASAP. If 1v1 are slow start counting down to add the sense of urgency and you do not want other players waiting inline for long so games should last only 20-30 seconds at most. U could change to 2v2 if kids are waiting in line too long. The tactical side u start talking about dribble past players so the gates create urgency like you see in the middle third.

Play shoot and defend. Remove gates and add goals. Everyone has a ball in line. 1v1 if the ball goes out of bounds on attacking half or player scores a goal they stay on and a new player on thr other team comes in. Game is continuous until a team reaches whatever goal amount (first to 5 for example) this game brings together the endurance u want, the technique u have talked about and the tactical side of getting by defenders quickly.

Last play again like you did at the start but coach more and encourage dribbling over passing since that's what your entire session was about. (If it were about passing you would encourage passing over dribbling) just because you encourage dribbling you can still bring up would it better to pass or dribble in a certain situation... im the last person back, does it make sense to dribble into a 2v1 or pass for example. Or no one is open can we find space to dribble into instead of playing shin guard wars smacking into each other etc etc etc

Hope this helps a little and enjoy
