Children want to succeed just as adults do this includes school work and assignments but all children learn differently.
One way that a child could learn is by watching someone doing it, while explaining it step by step. At first they may struggle to learn the new skill but once they grasp that information you can be assured that they know it. They have to visually see it being done then usually would like for that person to watch them do it to make sure that they are doing it correctly.
The second way that children learn is by reading it out of a book then applying what they learned and using that information. Some children and adults are not able to do that and would have a difficult learning if that was the only way to do it. This may be one of the hardest ways to learn something new.
The last way that children learn is by trail and error. This is mostly hands on experimental. These children like to be given a project then they would like to be left alone to figure it out for themselves. Many children will try to do something over and over again till they get it right. This can lead to frustration for the children. Many children will give up hope if they can not master it correctly within a few tries.
Not all children will learn the same way it is important to find out which way your child learns best then stick with that way. This is easier to do and accomplish if you are homeschooling your children, where you can take the time to teach them the way that they learn the best.
