The Argus Leader of Sioux Falls, S.D., reports the Sioux Falls School District is hoping to one day equip all of its middle school science classes with interactive SMART Boards. The district is hoping to buy 13 SMART Boards at a cost of about $3,500 each that would be used exclusively in its middle schools. The district already has 33 SMART Boards shared by its elementary, middle and high schools.
