Kumon Math Skills Workbooks are unique because they focus on teaching one specific skill from start to finish. With just the right amount of practice, children master each topic and gain confidence without becoming bored or frustrated.Using Kumon's step-by-step approach, this workbook introduces children to the concept of telling time by concentrating on the hours first, and then incrementally introducing children to half- and quarter-hours. Learning to tell time this way will also help children improve their general understanding of numbers.
