Do You Know Which Ones Will Grow? by Susan Shea is both an excellent story time book and a good book to help children with early literacy skills. This a fun and interactive story that helps to explain the concepts of inanimate and animate to children in a very easy and simple way. For example, one of the questions in the book is, "If a duckling grows and becomes a duck, can a car grow and become a truck?" Children have a lot of fun guessing the answers to these questions. I've read this book in a PreK story time and a preschool story time and the children absolutely loved it! Also, this story helps to build the child's vocabulary with words that they might not previously know, such as duckling, rust, kid (baby goat), owelet, and joey. Why is it important for children to hear a wide range of vocabulary and to expose them to many words? Children need to know the meaning of words to understand what they are reading.
