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. Kumons 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.
