I haven't tried this yet myself, but I've heard throwing a tennis ball across the ground in front of the shooter as a target is a cheap way to get them used to leading their target. Tennis balls are reactive when hit and re-useable. My son shoots a Mossberg youth model 505 410. He's already bagged quite a few Ptarmigan and Grouse. It's about time I start teaching him how to lead for wing-shooting too.
