Investigating History for Grades 3 and 4

Access Preview Materials for New Grades 3–4 Units!

Investigating History units for Grades 3–4 have been available in pilot form and will be fully revised and published for School Year 2026-27. To access a preview package including sample materials from a revised unit, fill out this form .

Investigating History is coming to third and fourth grades! Our upcoming courses align fully to the Grades 3 and 4 content standards and are being developed in collaboration with Massachusetts educators and experts. They engage students with the history of Massachusetts, the United States, and North America through a variety of lenses and a diversity of perspectives.

Throughout the pilot of the Grades 3 and 4 materials in school year 2024-25, DESE gathered valuable feedback from teachers, administrators, and students about how to make the Investigating History curriculum for these grade levels as strong as possible. In order to provide time to incorporate this feedback, the formal release of the Grades 3 and 4 Investigating History curriculum is scheduled for Summer 2026, in time for the 2026-27 school year.

Revisions to pilot materials will focus on building in more robust supports for multilingual learners; updating materials, maps, and sources to maximize grade-level appropriateness and usability; strengthening the consistency of routines and instructional strategies across all units and grade levels, and ensuring that skills and content flow coherently into the Grades 5, 6, and 7 materials.

Given the importance of these revisions, DESE strongly recommends that schools who were not part of the 2024-25 pilot wait to implement the full curriculum until the 2026-27 school year.
