Dạy học nội dung “Diện tích hình thang” (Toán 5) nhằm phát triển năng lực tư duy và lập luận toán học cho học sinh

Tóm tắt

Currently, the General Education Program for Mathematics is designed in the direction of developing the qualities and competences of learners. In particular, the competence to think and reason mathematically is one of the five mathematical competences that need to be formed and developed for students in teaching Mathematics. “Area of a trapezoid” (Math 5) is the basic content in the Math 5 program, providing many opportunities to develop students' ability to think and reason mathematically. This study presents a process for teaching Mathematics in primary school to develop students' competence to think and reason mathematically and illustrates this process in teaching the content “Area of a trapezoid” (Math 5). To develop students' competence to think and reason mathematically in teaching Mathematics, teachers need to ask open-ended questions, encourage students to explain, argue and debate to practice logical thinking; at the same time, it is necessary to evaluate learning outcomes through students' competence to reason and solve problems.
