This reading workbook is a companion book to 'Wise Owl's Moving Up', which is about an easy second grade level. For each lesson in the main workbook, this book has extra practice, which includes reviewing new sight words taught and phonics skills taught. It can be used for additional guided reading, independent seatwork or as homework. The stories in this workbook are intended for second graders, but some first graders may be ready for this. Also, some third graders, who haven't mastered the second grade reading level yet, can also benefit from it. I wouldn't use it for fourth grade or higher simply because the interest level and subject matter is geared for the six to eight year old. This workbook was just revised. I changed to bigger print for some stories and activities and also simplified some activities.
