What's the purpose of Kumon's curriculum?
Kumon was not designed to replace school math, but rather to complement it. Since its inception, millions of children have had the chance to internalize the math that may have been skipped over too quickly in school.
Our curriculum constitutes the core of school math. It reinforces the most important parts through small steps and repeated practice. This builds a solid foundation which children then utilize in school. In Kumon, every worksheet requires that the preceding one be fully mastered.
Keeping the end goal of high school math always in mind, Kumon has been able to streamline the curriculum choosing only the necessary concepts. The other aspects of school math are important, yet not essential for mastery of high school math.
