Workbook
Young students need hands-on activities. A teacher-created workbook can act as a basis for one of those types of activities.
Keep things simple. The workbook need be nothing more than a collection of papers stapled together. On the first day of teaching a new book, allow students to illustrate the covers of their own workbooks. This can provide a personal connection to the story at the outset of their study. You can use the pages as a place for students to draw artistic responses to the story. For example, if they've learned "house/mouse/train/rain" in class, then the lesson wrap-up may include time for them to draw a picture featuring the vocabulary words and labeled in English.
