The president and the first lady visited the Inspired Teaching School in Northeast Washington on Thursday.
Barack and Michelle Obama were at the school participating in a project to mark Sept. 11 as a national day of service.
Madison, a sixth-grader, told the president that when she heard the school was going to have a special guest she hoped it was going to be Beyoncé.
"Then I realized it was gonna be you," Madison said.
"Malia and Sasha would feel the same way," the president replied.
