Each Kumon Intro to Geometry and Geometry workbook begins at an accessible starting point and progresses in incremental steps so that children do not get frustrated or confused. Each new skill is taught, practiced, and reviewed so that your child will gradually build strong match skills. The exercises are carefully leveled from page to page so your child learns without anxiety and becomes more confident. This workbook contains several problems that children may find challenging. These problems are marked with a "light bulb" icon, and you will find them explained in more detail in the "How to Solve" sections on either page 96, 191, or 192.
