The Reading Kingdom is divided into five levels with six workbooks and six stories at each level. In Level 3, the books systematically introduce the past tense - a form that is critical to effective retelling of events. In addition, the stories are longer and extend over two books. Comprehension activities are introduced aimed at teaching children the vital skill of knowing how to summarize stories. This level of workbooks is designed to be used with Reading Kingdom Level 3 Books.
