How to Play T-Ball Race and some hitting tips

I use t-ball race as a chance to check how well my students can strike a ball using a long implement.
1. 2 kids step up to the t-ball box.
2. They hit the ball.
3. After both balls are struck I say go and they race to get the opposing teams ball and put it back on the tee before the opposing team gets their ball on the tee.
