PRODUCTIVE ROLL CALL
If you have a large class, you might spend quite a while calling the roll. Try doing this in a productive way. If, for example, the current lesson is about colors, you can ask your students to say their favorite colors when hearing their names instead of replying with the traditional PRESENT. Have your students use the language being taught when responding to their names during roll call. That way you comply with your duty while your students practice their English.
