We learned at a camp oh so many years ago to put it knee high 5' in front of home and try to hit it. We use an elastic band from the fabric store stretched to two plastic sticks that go in the dirt. It's a bit adjustable so I have DD stand in the batter's box and she pick's out the lowest height she thinks is going to be a strike that she'd swing at. Then she tries to hit it with the bottom of the ball on the the drop & change. We break it out when she starts drifting too far up in the zone.
