Jamella, 8, counts with an abacus at South Los Angeles Learning Center in Los Angeles, California March 16, 2011. The center is run by School on Wheels, which uses volunteers to tutor homeless children in shelters, parks, motels, and two centers. There has been a surge in the number of homeless children in Los Angeles in the last five years, due to persistent unemployment and mounting foreclosures.
