Consumable. One set of these consumable sheets is included in Language Arts D. You need one set per student. If you might reuse your Instructor's Guide and Student Activity Sheets in the future (for a younger child, for instance), we strongly suggest that you purchase an extra set of Activity Sheets when you buy the In Sonlight resource: https://www.sonlight.com/products/extra-language-arts-d-student-activity-sheets
