Each unit in the student's book is divided into four pages. On the first page, the grammatical point is presented in context through a dialogue and a visual cue. The second page contains an explanation of the grammatical point being addressed, while the last two pages offer various activities that allow students to practice what they've learned. The answers to all the exercises can be found at the end of the book. The complete audio content, including recordings of the dialogues, is available at www.enclave-ele.net/endialogo.
