With Brad Pitt filming Moneyball in Boston, Jolie, 35, has taken the couple's children with her to Hungary, where she just began shooting her directorial film debut.
"Angelina has enlisted her children into (an) elite French-American school that they will attend from next week on," a source tells PEOPLE of Pax and Maddox. "The school has kindergarten, too, where Zahara and Shiloh will attend."
Not only is Jolie making sure her children are comfortable in their new surroundings, but the actress is mingling with the Budapest locals.
"She came over to everyone in the vicinity, shook everyone's hands and introduced herself, as if we didn't know who she was."
