A Florida teacher made a grave mistake when she sent her first-grade students home with a racial slur on their spelling list. While the kids were supposed to be learning how to spell "bigger," they saw the n-word instead.

But when one mother, Terry Day, reached out to the Hamilton Elementary School teacher about it, she didn't like the answer she received.

"I said, 'Well, you didn't spell-check your word? You didn't proofread your word before you sent that out?' And (the teacher) said, 'It is a word.' And I didn't like the attitude behind that one,'" said Day to WESH 2

The school, which is located in the same city where George Zimmerman fatally shot unarmed Trayvon Martin, has since issued an apology to parents.

"The district is aware of the unintentional and unfortunate mistake regarding the typo on the spelling words worksheet," read a memo from the school. "The teacher involved has taught at Hamilton Elementary for many years and is extremely remorseful about the situation. The school has already fixed and updated the spelling words list and redistributed to the students in that particular class. In addition, a memo has gone home with students sincerely apologizing for the error."

As for the teacher, she reportedly told school administrators that she made the mistake because the letters "B" and "N" are close together on the keyboard and sent out a memo to the parents to notify them of the "misspelled word."

"Dear Parents: Please be advised there was a misspelled word on the blue spelling list I sent home yesterday," it read. "Please throw the blue list away and refer to this list for the next six weeks. I apologize for any inconvenience this may cause. Please contact me if you have any concerns."

This news comes after another teacher was suspended after she told a 13-year-old boy that he was going to be lynched.
