This CD contains a PDF with the exercises for each day of Daily Grammar Practice. Because the CD does not include the answer keys, it does not replace the teacher's guide. Also, you cannot print from the CD. The CD is an optional accessory that provides a convenient way to project each day's work if your students are not using workbooks.
