One more week of round 29

I realized this weekend, that i'm bringing TurboKick to Canandaigua middle school for their health and fitness day (this wednesday). So it looks like I'll be sticking with Round 29 for one more week. This is going to be the youngest group I ever tought, so I'm sure it will be interesting. Apparently my session has beeen getting quite a bit of interest. So I'm going to really have to prepare for this one. Any advice for teach a group of 8th graders?
