Well I don't know what exactly the answer format is supposed to be but a good way to boost self esteem in child is to encourage them in positive ways like when you tell them they've done a good job. Another way is too not compare them to others. When you compare a child to another it makes them feel like they need to be like them and that they aren't good enough, which can also lead to rebellious behavior because they feel thats the only way to get your attention.
