Every year in December, our volunteer expedition to the slum of San Fernando in Buenos Aires, Argentina is being launched. Volunteering lasts two weeks and is focusing on educational activities with children from the slum. Each cycle is composed of 20-25 volunteers. Volunteering is divided into two main tracks: first, the morning is devoted mostly to renovation and painting projects that are planned and executed by the volunteer delegation (for example the delegation of 2015, built a dining room to the children of the neighborhood ) secondly, the afternoon is dedicated to teach children in a variety of classes such as English, math, music, life values and principals and personal hygiene. One of the principles of our work is continuity and therefore every delegation work with the same children that the delegations that preceded them worked with. Thus we create a more valuable and meaningful action
