Kumon research has found that children master concepts with ease by tackling one skill at a time. In this book, your child will master reducing fractions to their common denominators to add, subtract, multiply and divide fractions without difficulty or frustration. This workbook will help students aged 10+ build upon their academic foundation and prepare them for school and even more advanced curriculum. Our Focus Workbooks concentrate on one challenging math topic per book to provide the rigorous practice your child needs for academic success.
