Students have diverse needs and learning styles. To make sure they all meet learning goals and succeed with rigorous standards, teachers must vary instructional activities. With increasingly stringent time constraints and high expectations, this is no easy task. William N. Bender’s four-page laminated quick reference guide puts differentiated instruction at any teacher’s fingertips. It displays models and examples of differentiated instruction with activities that can be done among peers, individually, or in a teacher-led format. It also outlines ways to modify the whole-class lesson plan to increase differentiation and use flipped classrooms and project-based learning approaches to differentiate instruction.
