This is a well edited math workbook, which fills the vacuum of the intellectual development over summer vacations, specifically, for the first grade children. Summer is so good. While having fun and relaxing, children may only need to practice math with this book for an hour every few days to review what they have learned, and advance what's coming the next academic school year. This book provides ample practices at the proper challenging level for a first grader to catch up and stay ahead. It cultivates and maintains a logical and creative mind. The book contains over 450 well-designed math practices, including over 50 basic word problems. It covers arithmetic, 2D/3D shapes, learning time, and counting money. Teachers have permissions to copy and distribute pages from this book for classroom use.
