I made three letters, "A", "B", and "C" into printable leopard templates so you can put it in a three ring white binder that has a clear pocket in the front.
Each child in Sunday school class will get a binder with a clear pocket in the front to slide any piece of paper or artwork they want in it. Just print these off for the kids and cut them out using decorative cutting scissors. I then added a piece of colored construction paper behind the cut out leopard letter and slide down into the front of the binder.
You can fill the notebook with lots of different things. They can add their own stuff that you had them draw or you can fill the binder with print outs of quizzes, bible trivia, or just whatever you want to put in there. You could even do prayer request sheets or lessons. I have three different printable prayer request sheets below that tie in with the leopard theme for the binder.
When the binder is full let the kids take them home. You could even personalize the letters with their names on them. Just open the printable leopard template up in your paint program on your computer and type their name.
During classtime if your children are old enough to write answers down then you could do a bible trivia and ask them to write their answers down. Then after they are done you could take the binders up and grade them and give the child a scratch and sniff sticker on their paper. Then the next time they open their binders up they will see what they got and find the sticker.
