"From picking things up to throwing things, to batting, to writing, to just coloring you'd do at home with him, he's always, always used his left hand," Alisha Sands said.

But when the pre-kindergartener was doing his homework, he was using his right hand.

"I just asked 'Is there anything his teachers ever asked about his hands?' And he raises the one and says this one's bad," Sands said.

When Alisha questioned the teacher in a letter, the teacher responded with an article that said that called left-handedness "unlucky," "evil," and "sinister."

The article, according to Alisha, said, "For example, the devil is often portrayed as left-handed."

Alisha went to the superintendent with the article, KFOR reported.

KFOR contacted the school's principal, who said she was aware of the situation and is investigating.

Sands said her son will probably transfer to another pre-kindergarten class and she plans to file a complaint with the Oklahoma Board of Education.
