I agree with the 3rd or 4th grade. You want the kids to have fun and learn proper technique. You put them in the position best suited to them and then put in a minimal amount of plays. If you want to do it right and help build up the entire program you use the same plays that the big boys use, just under different names. If the kids are learning fast then you can add a few more plays in. But proper technique is the most important. It helps the upper levels by getting it instilled in them young but it also helps the kids by protecting them and teaching them how to safely play the sport, (i.e. tackling and wrapping up the proper way). So yeah 3rd or 4th grade is a great time to start.
