1. Fraction operation: the addition, subtraction, multiplication and division of fractions is the key content of sixth grade mathematics in primary school. Students need to master the basic concepts of fractions, the relationship between denominator and numerator, the simplification and operation rules of fractions.
2. Decimal operation: addition, subtraction, multiplication and division of decimals is also an important content of mathematics in the sixth grade of primary school. Students need to master the basic concept, location, simplification and operation rules of decimals.
3. The nature of geometric figures: The geometric figures involved in mathematics in the sixth grade of primary school include triangles, quadrilaterals and circles. Students need to master the properties of these figures, such as side length, angle and area.
4. Data collection and collation: The sixth grade mathematics meeting in primary school involves data collection and collation, and students need to learn how to collect, collate and analyze data, and be able to use statistical methods to solve practical problems.
5. Solving equations: Solving equations is a difficult content in the sixth grade mathematics of primary school. Students need to master the solution of one-dimensional linear equation, including addition and subtraction of the same number on both sides of the equation, multiplication or division of the same number on both sides of the equation, etc.
6. answers to application questions: mathematics in the sixth grade of primary school will involve answers to some practical questions. Students need to learn how to turn practical problems into mathematical problems and use what they have learned to solve these problems.
In a word, the key and difficult points of sixth grade mathematics in primary school mainly focus on the operation of fractions and decimals, the nature of geometric figures, the collection and arrangement of data, the solution of equations and the solution of applied problems. Students should pay attention to understand and master basic concepts and operation rules in the learning process, and improve their problem-solving ability through a large number of exercises.
