KELLER, Texas — A Texas school district is reviewing a sixth-grade assignment that had students make a step-by-step plan showing how cocaine gets from a drug cartel to a street dealer.

KTVT-TV reports that a teacher in Keller, northeast of Fort Worth, gave out a science class assignment called “The Cocaine Trade: From Field to Street.”

Parent Scott Pick says he contacted administrators after his 11-year-old son brought home the study sheet for an assignment on “Following a Sequence.” He says he felt it was “a diagram of how to become a drug dealer.”

Administrators issued a statement Monday saying the assignment “will be reviewed before being considered for future use,” adding that the district will continue efforts to regularly “review, remind, and revise drug educational material.”
