The content of mathematics in Grade Three includes measurement (length unit and mass unit), addition and subtraction within ten thousand (II), quadrilateral, division with remainder, hour, minute, second, multiple digits multiplied by one digit, preliminary understanding of fraction, possibility, wide angle of mathematics (simple permutation and combination problem), position and direction, division with divisor as one digit, statistics, year, month and day (statistics).

Lay a solid foundation, prepare lessons carefully, and try to reduce students' learning burden. A well-prepared class is good for both students and teachers.

This semester, I have carefully studied the syllabus of the second volume of mathematics, fully grasped the objectives and difficulties of this textbook, and made a comprehensive plan for the teaching of this textbook, ensuring the smooth progress of teaching and preparing for writing every tutorial.

When preparing lessons, I changed the previous teaching process of preparing lessons again, focusing on preparing students. I insist on independent inquiry teaching, adhere to the student-centered teaching idea, flexibly design teaching methods for different mathematics contents, actively guide students to understand and master mathematical thinking methods in the process of actively exploring mathematical knowledge, and pay attention to the cultivation of students' mathematical ability.
