Mathematics in the first grade is the basic stage for students to learn mathematics. The mathematics knowledge in this stage includes basic operation, number recognition and graphic cognition.
The following is the introduction of mathematics related knowledge in grade one:
1, basic operation:
The first-year mathematics curriculum mainly includes addition, subtraction, multiplication and division. These operations include basic calculation methods and algorithms, such as carry addition, yield subtraction, intra-table multiplication, intra-table division and so on. Students need to master these basic calculation methods and apply them simply.
2. Recognition:
First-year students need to be able to read integers between 0 and 20 and understand the concept of numbers. At the same time, they also need to be able to compare the sizes of two numbers and understand the concepts of greater than and less than. This knowledge is the basis of mathematical operation and is very important for subsequent study.
3. Graphic cognition:
The first-year math course also includes the cognition of graphics. Students need to understand common plane and three-dimensional figures, such as circles, squares, rectangles, triangles, etc. They also need to understand the basic characteristics of graphics, such as the concept of edges and corners, the combination and arrangement relationship between graphics.
4. Time cognition:
First-year students also need to be able to recognize time, including knowing clocks and calendars. They need to know the hour hand, minute hand and second hand on the clock and be able to read the time. At the same time, they also need to be able to recognize the week, month and year and understand the relationship between them.
5, statistics and probability:
The knowledge of statistics and probability is also involved in the first-year mathematics curriculum. Students need to know how to classify, count and compare quantities, and understand the concepts of possibility and probability of simple events.
Students need to pay attention to practice and application when studying mathematics in grade one, and deepen their understanding and mastery of knowledge through a large number of exercises. In addition, parents can help their children learn by playing math games with them and solving practical problems. In a word, the first grade mathematics is an important stage for students to learn mathematics, which needs to be paid enough attention.
