1. Understanding of points, lines and surfaces: Students need to understand the concepts and characteristics of points, lines and surfaces and be able to classify them.
2. Understanding of straight lines, line segments and rays: Students need to understand the concepts and characteristics of straight lines, line segments and rays and be able to classify them.
3. Understanding of two-dimensional graphics: Students need to understand the concepts and characteristics of two-dimensional graphics such as circles, triangles, quadrangles and polygons, and can classify and name two-dimensional graphics.
final result
The learning content of the first volume of the fifth grade mathematics is rich and colorful, which requires students to study and master it seriously. Digital recognition, four operations, area and perimeter, graphics and other knowledge points are the focus of mathematics learning. Students need to practice and think more to improve their math ability. I hope the students can get good grades in the first volume of mathematics study in grade five, and lay a solid foundation for future study.
