The optional student workbook is not reproducible and does not contain the answer keys found in the teacher guide.
Student Workbook Volume Discount: If you purchase 6-10 workbooks, you will receive $2.00 off each workbook; 11-19 copies are $4.00 off each. You may request a further discount for quantities of 20 or more by contacting Rod at email@example.com or 706-745-1005.
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.
