A parent must know what level of math and any other subject, for that matter, that their child is performing at every school year. When children enter kindergarten and the school recommends that children know their ABC's and know how to count to twenty or whatever number, it is the parent's responsibility to make sure the child is prepared prior to enrolling in school.
Children can take classes from various organizations that will support their mathematical development. These organizations may offer classes in the summer or on the weekends. Some of the classes can teach children how to build robots, toy cars, toy airplanes, etc. These classes may be in the area of engineering, computer science or some other technical field.
For example, some programs use incentive tools similar to those found in video games. Each time a child completes a satisfactory score on a worksheet, the program congratulates them and gives them a score. With each level, the score increases. After a certain number of points, the student reaches a named level, such as captain or commodore.
Anything less could cause children to suffer a tremendous loss. The teacher that parents should be trusting to teach their child math is a person that will challenge their child regardless of their age. In addition to the challenges, the teacher should encourage children to try hard. Children need to know that their teacher cares about them and is not just trying to give them a lot of hard work.
