Our program has two text books that are taught side by side, the Grammar Text (322 pages) and the Workbook (283 pages). Each Workbook lesson has an accompanying MP3 sound file that has recordings of all the dialogs and new words. It is free to download and use in schools. It is very flexible. Since there is a lot of sturcture (sentence patterens) in the text, it allows teachers to deal with quick learners and slower learners in one group.
