The review questions are included in the instructor portion of the Activity Book to guide a discussion between the parent and the student. This is how the Activity Book was created- with questions to ask your student and possible correct student responses.
We found that many parents who were using the discussion questions with middle school students were taking the time to painstakingly type out the discussion questions with blanks for the middle school student to write the answer. So, after many requests, we made the Written Comprehension Responses product available in this answer/blank format for parents of older students.
We still recommend the "discussion" format for grammar stage students, but the more independent version is now available for download for older students as the Written Comprehension Responses. It is intended as an optional supplement to the Activity Book (not as a replacement) since the answers are included in the instructor portion of the Activity Book.
