I've coached little kids before... it's very rewarding. I'd rather coach kids under 8 or maybe under 10 than any other age group.
Advice: don't do the drills that everyone seems to believe are important to developing skills. They're a waste of time with little kids. There are tons of games that are simple to play, and simple to understand the rules of. The games are a lot more fun for the kids to play than doing repetitive boring drills such as dribbling the ball around a bunch of cones.
Examples:
Get 2 or 3 hula hoops (or more, depending on the number of kids you have.) Spread them out on a field. Give the majority of kids a ball, and have 2 or 3 kids running around without a ball. Hula hoops are safety zones. The goal of the kids is to get their ball from one hula hoop to any other hula hoop to score a point. The goal of the kids without the balls is to intercept the other kids balls and kick them away as far as they can. What's learned: kids automatically learn to look up at where they're going and who is around them while they're dribbling. Kids learn to keep the ball near to them while dribbling (rather than kick it 20 feet and run after it)
Another game: red light/green light... play it with soccer balls.
Monkey in the middle - played with 3 players in a triangle and one person trying to intercept the ball. Teaches passing skills, control, and how to play around defenders. Later, once the 3 players have learned to dominate the one person, you can add in a 2nd person to work on intercepting the ball... this teaches the kids not to bunch up on defense (as is natural at that age level.)
You don't have to tell the kids what skills they're learning, or the best strategies for each of the games. The skills come naturally and the kids rapidly figure out the best strategies. About the only thing that may help during the games is to yell to the kids to "Play monkey in the middle" - if the other team is bunching up on defense, your kids will creme them if they remember how well they can keep the ball away from the opponents while playing that game. Yelling "don't bunch up" is futile.
As the kids get better and better at the games they're playing, simply experiment with adding simple steps to the games. Example: after they've mastered the skills for monkey in the middle while they're more or less standing still (of course, the defenders do a lot of running), switch it so that the kids have to play monkey in the middle, but also move themselves from one end of the field to the other. When you stop and think about it, that's exactly what you want the kids to be able to do - pass the ball back and forth, avoiding defenders, while moving the ball down the field.
One other thing - the more games you play that require the cooperation of 2 or more players, the more you're naturally going to build teamwork.
