Stories from Social Studies are central to the Mind Missions experience. Leveled text stories provide informational text that meets students at their most appropriate reading level. The right leveled story will be easy to comprehend and challenging enough to allow for progress. Lessons for U.S. History are offered at three lexile levels that allow for growth throughout the year. Beginning stories are provided at a 700-800 lexile measure. On-level stories measure at a 800-900 lexile. Above-level Mind Missions stories measure at a 900-1000 lexile level. Using the most appropriate reading level encourages students to love informational text and the wonderful stories found in Mind Missions.
