1, number and algebra include the understanding and operation of logarithm. Understanding of numbers: the meaning and nature of integers, decimals and fractions, reading and writing of numbers, comparison of numbers, factors, multiples, prime numbers and composite numbers. Digital operation: integer addition, subtraction, multiplication and division, mixed operation, decimal addition, subtraction, multiplication and division, mixed operation, decimal addition, subtraction, multiplication and division, simple calculation and solving practical problems.
2. Graphics and geometry include graphic understanding, graphic calculation and graphic movement. Understanding of graphics: rectangle, square, parallelogram, trapezoid, triangle, circle, cuboid, cube, cylinder and cone. Graphic calculation: perimeter and area of rectangle, square, parallelogram, trapezoid, triangle and circle, surface area and volume of cuboid, cube, cylinder and cone. Motion of graphics: axis symmetry, translation, rotation, position and direction of graphics.
3. Statistics and probability include simple statistics, compound statistics, bar statistics, broken line statistics, sector statistics, probability and possibility.
4. Integration and practice are mainly about solving problems in life. Let the children find some problems by themselves, choose some problems to try to solve, and think about what to do first and then what to do. It doesn't matter if the problem can't be solved. Look at the difficulties encountered and let the children learn to observe and discover.
The importance of mathematics:
Mathematics is a science that studies concepts such as quantitative structure, change and spatial model. It is the foundation of physics, chemistry and other disciplines, and it is closely related to our lives. Therefore, learning math well is very important for each of our classmates.
In human society, people can't live without mathematics everywhere. With the rapid development of science and technology, mathematics plays an important role in daily life and social production. In ancient times, people recorded their labor results by tying knots, thus learning to share food. In modern society, mathematics teaching research shows that mathematics is also a creative activity of human beings. In this creative activity, it has strict deduction, proof, mathematical conjecture and incomplete induction.
With the progress of human society and the rapid development of science and technology, mathematics has not played a more and more extensive role in daily life and social production. Just as Mr. Hua once published the article "The Use of Great Mathematics" in People's Daily, he brilliantly described various applications of mathematics: the size of the universe, the size of particles, the speed of rockets, the cleverness of chemical industry, the change of the earth, the mystery of biology, the complexity of daily use and so on.
