We do have a "points" program that we use during Sunday School.
Each child has a card (the guide keeps it) for each unit that includes attendance, bringing Bible, bringing a friend, three scriptures corresponding to our unit, five or six questions from the unit, and a mega-point section that includes Lord's Prayer, Ten Commandments etc. that they may recite once a semester. These scriptures and questions are also on the back of their name tags for them to reference. We pull questions from each of the workshops they visit and their guides work with them at the end of each lesson to reinforce what they have learned.
Each year we have a special rotation that ends with a "Celebration Sunday." On this Sunday they "redeem" their points at our Sword Store.
The Sword Store is a glass-front cabinet with different items in it that is stocked through donations. One parent-volunteer stocks the store.
Our guides are able to tell us if there are any areas we need to teach differently based on what they see in the students' understanding. Some children may only be able to attend every other week due to parent custody and some children have a difficult time memorizing. This system gives everyone an opportunity to participate.
We also have a 5 point "Grace Coupon" for children who are very new or visiting on Celebration Sunday.
