Sometimes the differences can be as basic as language, says Syrian student Rama Salib. "I didn’t understand them because they speak Lebanese dialect," Salib said.

But since the program started, Khaled says he is already seeing better relations between the students.

Lebanese student Asma Harouk said: "When the Syrians first came, I didn’t know them, I didn’t interact with them. Now I feel there’s a friendship between us because of these activities."

With war in Syria raging just over these hills, it is hard not to think about the hardships some of the children have been through, says one of the teachers Lilianne Hamzeh.

"We are trying our best to make them equal, but sometimes you are finding yourself feeling with the Syrians much more because of what they faced before," Hamzeh said.

While refugees from Syria's war receive food, housing and blankets, few programs address their psychological and social needs.
