When do students in Vietnam learn the formula for calculating the area of a trapezoid?
Based on Section IV of the Mathematics Curriculum promulgated together with Circular 32/2018/TT-BGDDT:
Visual Geometry
Plane Shapes and Solid Figures
Observe, recognize, and describe the shapes and characteristics of some simple plane shapes and solid figures.
- Recognize trapezoids, circles, and some types of triangles such as acute, right, obtuse, and equilateral triangles.
- Recognize the net of a cube, rectangular prism, and cylinder.
Practice drawing, assembling, and creating shapes related to some of the plane shapes and solid figures learned
- Draw trapezoids, parallelograms, and rhombuses (using a grid).
- Draw the altitude of a triangle.
- Draw a circle with a given center and radius or diameter.
- Solve some problems related to measuring, drawing, assembling, and creating shapes related to some of the plane shapes and solid figures learned, integrating the application of geometry in real life, related to subjects such as Art, Technology, and Information Technology.
- Perform conversions and calculations with volume measurements (cm3, dm3, m3) and time measurements.
- Calculate the area of triangles and trapezoids.
Thus, according to the above regulations, the formula for calculating the area of a trapezoid is taught in the grade 5 Math subject.

Is it required to ensure the streamline and modern when designing the grade 5 Math curriculum in Vietnam?
Based on Section 2 of the Mathematics Curriculum promulgated together with Circular 32/2018/TT-BGDDT:
The Mathematics curriculum adheres to the fundamental regulations set forth in the overall program;
Inherits and promotes the advantages of the current curriculum and previous programs, selectively incorporates the curriculum development experience of advanced countries, and approaches the achievements of educational science, considering the economic and social conditions of Vietnam.
At the same time, the Mathematics curriculum emphasizes the following viewpoints:
- Ensure conciseness, practical relevance, modernity
The Mathematics curriculum ensures conciseness, practical relevance, and modernity by reflecting the essential contents that must be addressed in the general education system, meeting the need for world understanding as well as learners' interests and hobbies, suitable to the world’s approach today. The curriculum adheres to the spirit of “mathematics for everyone,” where everyone can learn Mathematics but each person can learn Math in ways suitable to their preferences and individual abilities.
The Mathematics curriculum focuses on applicability, connecting with real-life or other subjects and educational activities, especially those aimed at implementing STEM education, aligning with modern development trends in economics, science, social life, and globally pressing issues (such as climate change, sustainable development, financial education,...).
This is also reflected through practical and experiential activities in mathematics education in various forms such as: conducting projects and study projects about Math, especially projects and study projects about the application of mathematics in real life.
Organizing math games, math clubs, forums, seminars, math competitions,... create opportunities to help students apply their knowledge, skills, and personal experiences to real-life situations creatively.
Thus, the grade 5 Math curriculum, in particular, needs to be streamlined and modern.
