WASHINGTON (CNN) -- U.S. schoolchildren still have work to do when it comes to mathematics, the secretary of education said Wednesday. Education Secretary Arne Duncan says U.S. schools need to be better equipped to teach math. Arne Duncan, releasing a report on the Department of Education's latest examination of how well American children are doing in mathematics, said no one should be satisfied with what it found. "Today's results are evidence that we must better equip our schools to improve the knowledge and skills of America's students in mathematics," he said. "More must be done to narrow the troubling achievement gap that has persisted in mathematics, and to ensure that America's students make greater gains toward becoming competitive with their peers in other countries."
