5th Grade Textbook Research Question

Hello, my name is Cailey Hauver and I am a Sociology graduate student at the University of Connecticut. I am currently conducting research on the textbooks used to teach U.S. History in Massachusetts public schools. I am particularly interested in finding out which textbooks are currently used in 5th grade social studies classrooms. If you are a 5th grade social studies teacher or curriculum coordinator, it would be most helpful if you could provide me the title, the publication year, and the publisher of the textbook your class uses. If you are interested in aiding me in my research, you can contact me at cailey.hauver@uconn. Thank you!
