The Level 4 Textbook is the latest and most advanced edition of the Speak Lakota! series. It reviews and builds on vocabulary from Levels 1-3, while expanding into more complex grammatical areas. The Level 4 is a departure from previous textbooks in that it is designed solely on communicative language principles. It helps the student not merely know the language through rote memorization of patterns, but through encouraging a process of discovery that internalizes the languages into the student's active language framework. The textbook is also heavily integrated with listening activities- double those of previous textbooks. It introduces language students to over 60 new verb paradigms and 700 new vocabulary words.
