Homeless children can be hard to identify and even harder to help. But teachers can do a great deal to make sure that they do not fall through the cracks. Teachers of highly mobile students must develop the skills to make these children and youth feel welcome while quickly weaving them into classroom routines. They must rapidly assess new students' abilities, recognize emotional needs, employ a variety of teaching strategies, arrange for students to complete homework at school, and provide individual or group tutoring. They must also routinely play the role of social worker and match highly mobile students and their families with additional resources. Providing an atmosphere where the child feels safe and nurtured is the most critical thing teachers can do to ease the social alienation resulting from high mobility. Effective teachers establish relationships and trust with homeless students whose belief in themselves and the future may be stunted or badly shaken. (Contains 3 online resources.)
