Soccer's a different game, and the kids are half the age of your high schoolers Cuse. There are plenty of things you can do. You can tell the team not to shoot until they have X amount of passes strung together, or with their off foot, or at a more advanced age, to try and score on aerial balls. Kids at 7-9 are pretty prone to giving up when their hopelessly outmatched. Not scoring(or putting restraints on your team) is the sporting thing to do out of courtesy. This is what my brother's high school coach would do (unfortunately he got a better offer by the time I was about to play for him). But he would have them make a certain number of passes, or he would make it so they can only score on a header, etc.
