A game that simulates killing classmates is leaving a bad impression on parents of a middle-school in New Hampshire.

According to a local television, 5th graders at Iber Holmes Gove Middle School are playing a game called, "Mafia," where, according to Wikipedia, some players are "Mafia members" and others are "honest people." Each team tries to eliminate the other team, with the "honest" group trying to figure out who the Mafia members are.

WMUR-TV in Manchester reports, Rae Coppola said she was disturbed to see the homework assignment her 11-year-old daughter was getting ready to turn in.

Coppola says, "There's absolutely nothing fun about killing people and for these children to have to come up with ideas on their own about how to kill people."

"I had noticed [my daughter] acting weird. She was up to 11:30 at night. She couldn't sleep, had migraines, had a stomach ache."

According to WMUR, after seeing the assignment, she went to the school the next day to complain.

"I was just absolutely mortified that they're teaching violence in schools. Teaching starts at home, and I'm trying to teach my child that certain things are not appropriate. I don't even let her watch PG-13 movies."
