Increasing motivation for practice

I currently teach lots of little ladies who love jewellery. I decided to use an idea I’d seen and get them to build their own bracelets with different coloured beads depending on how much practice they’d done each week. Pink = 4days practice, silver = 5 days, gold = 6+. They also get an extra silver bead if they do any review pieces during the week. They are really enjoying it and find the little competitive element motivating! I also have some young boys too and we are using the same idea but with key rings! (Of course if they want to have a bracelet they can do that too)!
