Under the background of double new, this paper explores the application of large unit teaching in high school mathematics efficient classroom, aiming to help front-line educators better interpret curriculum standards, control textbooks, improve mathematics teaching efficiency, cultivate students ' mathematics core literacy ability, and cultivate all-round students. This paper briefly describes the idea of large unit teaching in high school mathematics, explores the basic steps of large unit teaching, and provides teaching reference for front-line educators by case demonstration method.
