Parents in one Georgia school are demanding an apology after a third grade math class used images of slavery and even slave beatings as part of the lesson plan.

Students at Beaver Ridge Elementary School in Norcross, Georgia, were reportedly given a math worksheet that contained such questions as: “Each tree had 56 oranges. If 8 slaves pick them equally, then how much would each slave pick?” and “If Frederick got two beatings per day, how many beatings did he get in 1 week?” — according to a report in the Atlanta Journal Constitution.

The controversy went public after several parents contacted the school, and then the media, after their children brought the worksheets home as homework.

Two thirds of the students at the school are Hispanic, and approximately 24 percent are black, the newspaper reports.
