At the end of all levels, children are greeted by a celebration and encouraged by a computer voice to change topics.
There was a time that the United States of America had some of the highest mathematic scores in the world for students in grades k through 12. A lot has changes since those days, and in order to help children get back on the path to being good mathematical students parents need to play an important role.
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.
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.
