This is a horrible example of an educational lesson by one teacher, who thought she could make a point by lining up her class by the colour of their skin. 

Children in Southeast London were told to line up according to skin color as part of a primary school lesson about race.

Teachers had 30 students ages 10 to 11 to “organize themselves from the darkest to the lightest” with the last boy being picked on because he was the “blackest,” the Daily Mail reported.
