What is the difference between Easy Grammar & Daily GRAMS?
The Easy Grammar series is the teaching series. These texts teach the concepts of grammar. The teacher edition contains teaching instructions, answer keys, and reproducible student pages. When you open the book the answer key is on the left side and the student page is on the right. The student workbook would save you from having to make copies of those student pages in the teacher edition. Also, the tests are in the teacher edition. However, if you don't want to make copies of the tests then you can get the student testbooklet.
The Daily Grams series is the review series. This is a daily, 10-minute grammar review designed to increase mastery of the concepts. The teacher text has the reproducible student pages in the front of the book and the answers in the back. This is the only book you need if you have one child (the child can write directly in the book). If you have more than one child and don't want to make copies then you can get the student workbook.
