Description Bang! Bang! Boom! - Fireworks are loud! Is there a way to go outside and still enjoy them? New Shoes - Look at these new shoes! Is there a way to keep them clean in the rain? Level 0 - Lilac books support children's developing speaking and listening skills as well as the linking of sounds and letters. Children are encouraged to enjoy books from as early an age as possible. However, the focus of this phase is on listening to and repeating sounds, rather than on directly reading words. In our level 0 books, there are no words.
