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.
This teacher should believe in giving homework every night. Homework reinforces what was taught and learned in class and gives the parent and the teacher a chance to see if the child understands that information.
When trying to develop good math students, all avenues should be tried. Parents can make additional progress by allowing children to visit work locations that utilize a lot of math. Children should be exposed to as many careers as possible. Careers in math and even science should be on their list of considerations. Parents should inform children which careers require them to have good math skills.
