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.
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.
As children become more confident in their math skills, give them worksheets one grade level above their current grade. Help them if necessary, but when students become successful in the upper level workbooks; their confidence will really improve. The seed will be planted early and parents can watch as it grows.
There are both similarities and differences between the new computerized programs and the former method of writing in math workbooks, tearing out the pages and turning them in.
