Kumon Workbooks follow the Kumon Method, a proven learning system that helps children succeed and excel in math. Kumon Workbooks gradually introduce new topics in a logical progression and always include plenty of practice. As a result, children master one skill at a time and move forward without anxiety or frustration. Most grade-school workbooks try to cover the full range of topics in one workbook, and as a result do not dedicate enough pages to important mathematical concepts. Kumon's research has found, however, that children find learning easier when they tackle one skill set at a time. With these findings in mind, we designed our newest line of workbooks to help children with one particular mathematical skill set per book. Untuk pembelian terpisah bisa chat kami untuk linknya ya.
