Learning to tell time requires repeated practice, but it can become a tedious task. This book first teaches the principles of reading a clock and then designs a series of problems to help children gradually become familiar with it. By learning the principles first and then solving problems through writing and reading, children can understand more naturally. In particular, the book includes cute character illustrations by the famous artist ChaCha, which will increase children's interest in learning. This book is suitable for 7-year-old children who already know numbers up to 100, and it is also effective for first-grade elementary school students who need more practice in "reading minutes."
