KELLER, Texas (AP)  A North Texas school district has halted an assignment requiring sixth-graders to make a step-by-step plan on how dealers distribute cocaine.

KTVT-TV ( ) reported Monday that a teacher in Keller issued an assignment called: "The Cocaine Trade: From Field to Street."

Administrators responded by saying they take drug abuse very seriously and the study sheet will be reviewed before being used again.

Parent Scott Pick says his 11-year-old son was sick, missed some school at Bear Creek Intermediate and was doing makeup work. Pick reviewed his son's assignment and came across a section about "Following a Sequence."

Pick says the assignment lists the steps from drug cartel to street dealer.

Pick declined to let his son do the assignment and contacted administrators in Keller, 15 miles northeast of Fort Worth.
