You get both Spanish 1 Pro levels as instant PDF downloads: the K-3rd edition and the 4th-8th edition. Each is a complete 35-week, one-lesson-a-week curriculum with lesson plans, printables, flashcards, games and songs, written by a native Mexican speaker for parents who don't speak Spanish themselves. Buy once, teach every child in the family at their own level. The 29 pronunciation videos are not included in this bundle; they come with the Super Bundle.
