A "Flipped Classroom" is an instructional strategy that essentially flips the concept of learning. The focus of student learning, by lecture, is done outside of the classroom, typically with a video and guided notes. This allows for homework to now be done as an activity during class, which allows the teacher to focus on student development and comprehension during the class. This free lesson includes the Video Lesson and Guided Notes for Section 1.1 - Understanding Algebraic Terms.
