Hierarchical Design Optimization Strategy of Primary School Mathematics Homework from the Perspective of Core Literacy

Homework is the extension and expansion of classroom teaching, it is inextricably linked with teaching and evaluation, and plays an irreplaceable role in consolidating, expanding, evaluating and reflecting on teachers' teaching and students' learning. The "double reduction" policy requires reducing the heavy homework burden of students, and emphasizes improving the quality of homework design and encouraging the layout of hierarchical, flexible and personalized homework. In view of some problems existing in assignment design, this paper studies hierarchical assignment design strategies from the aspects of level, form and evaluation, so as to make assignment more scientific and reasonable, truly reduce the burden for students, and promote the overall development of students.
