FLORENCE, Ariz. – An Arizona middle school teacher was sent home after parents complained about a poetry assignment featuring profanity laced lyrics from Ice Cube’s 1990 gangsta rap “Who’s the Mack?”

“What the hell was he thinking?” Carrie Scott, parent of an eighth-grader in the Florence Unified School District language arts class, told CBS 6. “It was horrifying. It was a nightmare. How do you grade this? How do you grade a 13-year-old talking about sexual requests for money?”

The news site reports that an unidentified language arts teacher played the music video for “Who’s the Mack?” for students recently and sent them home with the lyrics and an assignment to identify similes, metaphors and other poetic elements.

Parent Sam Washburn called 12 News to highlight the assignment he found in his daughter’s backpack because, although words like f*** were blacked out, other offensive language and themes of prostitution, drug use, domestic violence, sex acts in the song really made him mad.

“You just kind of take for granted your 13-year-old daughter’s got curriculum at school that’s appropriate for school and come to find out that’s not the case at all,” Washburn said.

His daughter, Spencer Washburn, told the news site she completed the worksheet to avoid a bad grade, but felt violated by the assignment.

“I am in student council, and I would not want to get kicked out,” she said.

Many parents who were offended by the explicit lyrics and themes in the assignment voiced their frustrations and call out the teacher on Facebook over the weekend, which prompted district officials to respond on the school district’s Facebook page Tuesday.

According to the post:

“Florence K-8 was notified over the weekend of an alleged inappropriate song being used by a teacher as a class assignment. Our administrative team at Florence K-8 acted quickly to investigate the claim and found the song and assignment to be inappropriate. The Florence Unified School District Office was notified and the teacher was reassigned to home pending a thorough investigation. Appropriate action will be taken in accordance with district policy to ensure professional conduct in all our faculty and staff. We assure you that the safety and well-being of our students is our priority.”

“The language is the biggest issue,” Florence district spokesman Richard Franco told CBS 6. “It’s not something that’s part of our curriculum in any way, shape or form and it’s not something that our district condones being taught in our classes.”

Teachers submit lesson plans for review a week in advance, he said, and the teacher’s did not include the Ice Cube assignment.

CBS 6 did not identify the teacher, but said it was his first year in the district. He’s now at home waiting for district officials to decide his fate.

Scott, and undoubtedly other parents, believe he should be fired.

“I believe a teacher is paid to teach my child how to read and write and do math and learn history,” Scott said. “It’s my job as a parent if I want to teach them the lessons about pimps and hookers. That’s my job. That’s not their job to expose my children to explicit music or lyrics.”
