The first level books, Uno y Dos Are One and Two, and Arriba is Up! (titles referring to the English/Spanish version of the books) introduce vocabulary directly in vocabulary lists and then give example sentences, all flowing into the story. Uno y Dos Are One and Two, demonstrates numbers, colors and shapes in the new language while telling the story of a cute kitten's birthday party. Arriba is Up! takes the reader through a little elephant's adventures in the park with his mother and playmates as they explore, play, and learn, all things that young readers can relate to and will want to know how to express in their new tongue. Level two books cover the same themes as the level one books but focus on a more thorough level of language: sentences, prepositions and command structures.
Once the basics are well-understood, learners of a new language can advance to the second level books. The second level books teach through storytelling. So far, titles include Velero is a Sailboat and Little Bird. Similar to an easy reader or leveled reader, the level two books use basic vocabulary repeated throughout to tell the story so that readers practice within the context of an entertaining tale. The vocabulary and sentences are more advanced than those in the level one books. Joyce Fernandez, founder of My Second Language Publishing intends on having more level two books out in the ten featured languages very soon.
