1. First, we studied the concept and basic properties of fractions. A fraction is a mathematical expression, which usually consists of a numerator and a denominator. The numerator is above and the denominator is below. The size of the fraction is determined by the relative size of the numerator and denominator. For example, 3/4 is to divide a whole into 4 equal parts, of which 3 parts are the value of the score.
2. Through review, we know that scores have some basic properties. For example, the numerator and denominator of a fraction are multiplied or divided by the same non-zero number at the same time, and the score obtained is equal to the original score. We also learned how to compare the size of two fractions and how to add and subtract fractions.
3. Secondly, we also learned the operation rules of fractions. The key to fractional addition and subtraction is to find the least common multiple of the denominator and then divide it. Fractional multiplication means numerator and numerator multiplication, denominator and denominator multiplication. The rule of fractional division is to turn the divisor into the dividend in reverse and then multiply it with the original dividend. These rules help us to perform four operations of fractions and deepen our understanding of fractions.
4. Finally, we also learned the application of fractions. For example, when solving practical problems, we often need to use scores to express the relationship between parts and the whole. For example, there are 50 students in a class, 30 of whom are girls, so the proportion of girls in the class is 30/50, which is 3/5.
Methods to improve math scores
1. Establish a solid foundation: Mathematics is a highly coherent subject. If you want to get good grades in the later period, you must pay attention to the study of basic knowledge. Ensuring the understanding and mastery of basic concepts, formulas and principles is the basis for building mathematical thinking and solving problems.
2. Cultivate good study habits: Establish good study habits, such as reviewing regularly, sorting out notes and doing exercises. Through regular review, you can consolidate what you have learned; By sorting out notes, you can record important concepts, formulas and problem-solving methods; By doing problems, we can deepen our understanding of knowledge and improve our ability to solve problems.
3. Active thinking: Mathematics is not only memorizing and imitating, but also emphasizing understanding and innovation. When solving problems, learn to think positively, try to solve problems with what you have learned, and don't wait for the teacher's answer. Ask for help: Don't be afraid to ask for help if you have problems or don't understand.
You can ask the teacher or discuss with your classmates. At the same time, you can also find some math learning resources, such as online tutorials and problem sets. Keep a positive attitude: Math learning may encounter setbacks and difficulties, but keep a positive attitude. Believe in your own ability and believe that you can overcome difficulties.
5. Take part in the math contest: Taking part in the math contest can exercise math thinking and problem-solving ability, and at the same time expand math knowledge. This can not only improve math scores, but also lay a foundation for future academic development. Using science and technology to assist learning: Now there are many scientific and technological means to help us learn mathematics, such as using online learning platform and mathematics application software.
