A great incentive for your students is to give them a Challenge List.
Each time the student completes a piece (to your requirements), they can write the piece on their Challenge List. Watch their excitement grow as they get closer to the end of their list, until they earn their Challenge Certificate!
Suitable for all ages and available in versions for 20, 30, 50 or 100 pieces (as indiviual certificates or bundle package).
