Many children squeeze into this preprimary classroom at the Kiryandongo refugee settlement in northern Uganda, and many others peer through the windows and doors to listen in as well.
Most of them are refugees who have fled violence in neighboring South Sudan.
They are part of 17 million of school-age children around the world who are forced to be refugees or displaced in their own countries due to conflict.
Kiryandongo counts close to 50,000 refugees from South Sudan, a huge increase from 5,300 in 2013.
Earlier this week, as we observed World Refugee Day, we are reminded that millions of children like the ones in this photo need our support to ensure that their education is not interrupted, that their lives, already disrupted by turmoil, retain a semblance of normalcy, and that they can continue to dream of a better future for themselves, their families and their countries.
