The situation is even worse for refugee children, most of whom begin school late, and for whom education is also the only hope out of the camps.
At the Daadab Refugee Camp in Northern Kenya, a local radio station, Gargar FM, is giving hope to children seeking an education.
The aid agencies have appealed to the Ministry of Education to urgently ensure that systems for remote learning are in place, as the most marginalised children have been hit hardest by the closure of schools.
Save the Children says priority should be given to children who cannot access digital learning tools - those from low-income households and in rural and marginalised areas, those with disabilities, and those in refugee camps.
Ms Le said other measures to help the children include supporting distance learning by making families aware of the radio lessons being offered by the Kenya Institute of Curriculum Development for formal learners, and supporting the recording of lessons for non-formal learners.
