“双减”背景下的数学作业动态分层设计，既可以因材施教、减轻学生作业负担，也可以避免因分层而导致的学生两极分化加剧。因此有必要建设数学分层作业题库，提出数学分层作业题库建设步骤、动态分层设计的常用方法，以及对分层作业研究进行展望。

Dynamic tiered design of Mathematics assignments in the context of“double reduction”can not only teach students in accordance with their aptitude and reduce the burden of students, but also avoid the increasing polarization of students due to tiers. Therefore, it is necessary to build a database of mathematical tiered assignments, put forward the steps of construction of a database of mathematical tiered assignments and the common methods of dynamic tiered design and propose the prospects of research on tiered assignments.
