Yes, you have to be reasonably skilled to appreciate the joys of bouncing that tennis ball around. That's a skill-maintaining fun thing to shoot, not a skill-building plan.
Or just toss your ball/can/whatever onto a dry dirt berm, if you're outside.
I save all my larger cardboard for the range, there's a punch to make holes matching the hangers at the target line mounted to the wall, and everyone brings in cardboard.
For brand-new shooters, a big expanse of clean cardboard with a large target stapled to it is an ideal first target, by the end of a session I generally have them on 9" circles or regular printer paper, for something to take home and stick on the fridge.
