Math education consultant Marilyn Burns finds that teachers ask her the same three questions so often she's named them "The Big Three": What can I do with students who finish their math work more quickly?, How can I free up time to work with kids who need extra help?, and How can I differentiate math learning experiences? Burns, who works closely with a 4th grade class in California, describes math menus, a strategy she uses to help this class's teacher address the Big Three. A math menu is a list of options for math activities--done individually or in pairs--posted on chart paper. Many activities are differentiated, and students choose the order in which they want to do the activities and which, if any, they want to repeat. Burns describes a lesson on addition and subtraction skills presented in this class and a differentiated math menu option she and the teacher created to extend students' learning of the concepts and skills in the lesson.
