ABC TO MASTERY LEVEL 1- Take the first step towards learning Spanish with ABC to Mastery! This unique approach to learning your ABC's was developed by educators and starts with a set of terms that start with the same letter in English and Spanish. As you move through the series, you'll be introduced through vivid photographs to characters who will bring the initial set of terms to life as you go from the term to sentences in present, past, and future tenses, and then on to paragraphs and pages of content.
