A Georgia school is under fire after one of its teachers introduced her students to a “demeaning” slavery education game about the Underground Railroad.

Delores Bunch-Keemer said her 10-year-old granddaughter was visibly upset after playing an Underground Railroad simulation activity in class at Cheatham Hill Elementary School. According to Atlanta’s WSB-TV news, the young girl and her classmates played the role of enslaved people trying to escape the plantation and reach the Underground Railroad.

Their paths were directed by the roll of dice, as students either escaped further into the woods or were caught and sent back to the plantation.
