NBC News spoke with teachers around the country who said they were working to reshape lesson plans to better reflect the fullness of America's multicultural history.

"I did hear a lot of responses from teachers about their need to have more education around Black history because of George Floyd," said LaGarrett King, the founding director of the Carter Center for K-12 Black History Education at the University of Missouri.

King, who is an associate professor of social studies education, said it's important to understand intersectionality within Black history in terms of "exploring the full humanity of Black people," including women, LGBTQ people, the disabled, the poor and other groups.

Janella Hinds, a global studies teacher at a high school in New York City, said teachers also re-examined those topics at the recent convention of the American Federation of Teachers, a major teachers union.

Hinds said she was working with her school, Brooklyn's High School for Public Service, on creating an elective course focused on activism and movements against oppression, as well as linking current events into her global studies class.

Adina Goldstein, a seventh-grade social studies and English teacher in Philadelphia, said she had been thinking about how to turn her social studies class into more of an ethnic studies course to reflect more African American and Latin American history.

Goldstein, who is Chinese American and Jewish, said she recently spoke with a former African American history teacher, who said "something really insightful to me: 'We teach what we know.'".

She said she believes school districts should invest in giving teachers resources and continuing education so they can educate themselves and improve their curricula to better reflect their students' identities?

Kimberly Rodriguez, an English language arts teacher at John Adams High School in the New York borough of Queens, said she would be working with her school this month to shift lessons to relate more to their students' lives in the wake of the national moment.

Anton Schulzki, a high school teacher in Colorado Springs, Colorado, said the state recently held a virtual conference at which dozens of social studies teachers discussed changing their approaches to their curricula to move beyond their own biases

There's a push among a lot of teachers, period, across the country to really examine how we approach things," said Schulzki, who is president-elect of the National Council for the Social Studies
