Material reward refers to the material reward given to children when they behave well, such as candy, toys or other small gifts. When educating children with material rewards, we should first let them know what kind of behavior will be rewarded, and make clear the time and quantity of rewards. For example, you can tell your child that if he behaves well in class, he will get a candy as a reward every day. In this way, children will know what they have to do to get rewards, and they will be more motivated to complete these tasks.
