Children able to develop the ability to fulfill simple tasks, even "boring tasks" with accuracy, are develping self-control. You will be able to identify students who are internally motivated and students who are externally motivated through this simple test. Students who take the time to be accurate demonstrate self-control; while those who speed through it lack self-control. This is a tool to develop self-control and show students evidence of their character development. This test should have a time limit.
Inspired by the book How Children Succeed by Paul Tough
