As the International Teacher for Miina Härma Gumnaasium in Tartu, Estonia, I teach classes in English that include children from Estonia, Romania, Latvia, Lithuania, and even Pakistan besides Britain and the United States. Lesson Planet helps me find many worksheets and lessons that feature hands-on activities, good graphic organizers, clear, simple language and diagrams, step-by-step math explanations. It is basically very useful for helping a teacher with a largely ESL population. Moreover, I must develop my own teaching materials since I follow the Estonian national curriculum PLUS the national standards of the students, which can be difficult to reconcile together -- never mind, trying to find a textbook that suits (and, I might add, English-language texts are not easily obtainable here).
