If you want to have fun, and not care about who wins and loses that is fine, go play at the YMCA, they don't keep score and everyone gets a blue ribbon.
Here we keep score. This was 14 and under AAU basketball and was almost 15 years ago, and though I have a problem with some people's attitude about winning at all costs for certain ages, under 10, I think if channeled correctly the idea of winning = good, is not a bad thing for children to learn.
You don't want children to learn: do nothing, don't try, don't care = good, participate, try hard, work hard = good; There has to be some level of accountability.
As someone who has recently coached youth sports, we had a rule that if you showed up late for practice that you had to run a lap before you began practice. Of course the kids had no problem with this rule because it wasn't a very long run and they understood the principle behind it, if Im late I have to run. Seems simple enough. Of course, one day a parent brought their kid late to practice and I told the kid "Give me a lap", and the kid didn't complain, in fact his response was "Sure thing, Coach." Now the parent sees this, and makes the comment to me, that it wasn't the kid's fault that he was late, that it was her fault, and she didn't think it was right that he should have to run the lap, and so I said, "Well you can run the lap, if you want"
