An Illinois teacher is receiving a lot of  heat after a failed attempt to get students to pay attention to their math lesson.

Wednesday was not your typical school day at Roxana Senior High School, after a math teacher came in with a new lesson plan. The teacher asked students, “How high they would you be three hours after using cocaine and how much would they owe a dealer for $1,000 payment paid at only 25 percent a day for a year?”

Apparently, this was an innocent attempt to get the students to simply pay attention in class. Teachers, as well as students of Roxana Senior High were extremely baffled.

One parent, Christy Scott made a comment after viewing the photo of the assignment on News 4,

“Wow. That’s a school math problem? We don’t need to be teaching children how long it takes to filter cocaine out of their bodies. That is ridiculous. That is not what we should be doing. We should be preventing this and not teaching them how to get rid of it.”

Following the incident, Roxana School leaders released a statement:

“Student welfare is always the Roxana School District’s #1 priority. Unfortunately, unacceptable examples were used in a high school math class causing some parent and student distress. The district views the use of yesterdays’s classroom examples as a demonstration of poor judgement. The district is addressing the matter with the faculty member and those impacted by this incident. The faculty member has apologized to students and parents for this lapse in judgement and has reiterated the intent was never to promote or make light of illicit drug use. The district is taking the necessary measures to ensure that the damage is repaired. The district is addressing this issue as a personal matter according to district policy.”

They declined to release the teacher’s identity, but according to News 4, they were able to track him down. “He chose not to comment on the story, but has apologized to students, saying that “his intent was never to promote or make light of illicit drug use.”
