As a means of assessing student comprehension, The Story of the World Activity Book has "Questions for Review" for each chapter of the text. Younger children can respond orally with the parent/teacher. Older students, starting in about 4th grade, can work more independently and answer the questions in writing.
The Review Questions Worksheets PDF has the questions written out for the student, leaving space for a written response. The "answers" are in the Activity Book. This is an optional resource; it might save some time if no one has to write out the questions.
This product used to be called the Written Comprehension Responses. We changed the name in 2021 to make it more descriptive. The product is the same.
This article explains how the Review Questions Worksheets fit into The Story of the World product set.
