School administrators are responsible for choosing the type of curriculum taught to children. As long as they are learning, the curriculum is considered effective. Using computer games as a tool is one option available to today's schools.
Some have a time limit to complete tasks, much like a game. If the math problems are not completed in time, a buzzer sounds indicating that they are out of time. This raises the competitive level from simply completing tasks to competing for how quickly they can do it, and do it correctly.
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.
Parents who are positively involved with their children and want the best for them will make sure their children are keeping up with their math skills and are successful in school.
