In a growing number of classrooms around the country, students are learning a very different story about Thanksgiving than their parents did.

Instead of focusing on a joyful turkey feast in 1621 shared by Pilgrims in Plymouth Colony and Wampanoag Indians, some educators today frame the holiday around the way Native Americans were treated by Europeans who settled on the continent.

In North Carolina, for example, teachers receive this guidance from the Wake County school system’s Office of Equity Affairs, as shown in this tweet by Lauryn Mascareñaz, a director in that office:

The office provided links to help teachers look at the holiday in “a historical and culturally appropriate way.”

The nonprofit Center for Racial Justice in Education has compiled a guide for teachers on how to approach Thanksgiving, which you can find here. And one educator, Debbie Reese, posted a striking series of tweets (see below) in which she tells teachers how not to teach Thanksgiving.

Reese has taught elementary school in traditional public schools and in two schools for American Indians: Riverside Indian School in Anadarko, Okla., and Santa Fe Indian School in Santa Fe, N.M.

A tribal member of Nambé Pueblo in northern New Mexico, she taught children’s literature, American Indian studies and other courses at the University of Illinois at Urbana-Champaign. And she is the founder of an organization called American Indians in Children’s Literature.

Here are many of the tweets she posted:
