1, mathematical knowledge: this aspect mainly covers the mathematical knowledge involved in this unit, such as integers, decimals, fractions, etc. For each knowledge, you can mark its definition, nature and simple application. For example, in the integer part, it can include the concept of integer, the type of integer (positive integer, 0, negative integer) and the properties of integer. In the decimal part, it can include the concept of decimal, the types of decimal (pure decimal, with decimal) and the properties of decimal.
2. Mathematical skills: This aspect mainly covers the mathematical skills involved in this unit, such as calculation ability, comparison ability, geometric figure cognitive ability, etc. For each skill, you can mark the application method and the points that need attention. For example, the calculation ability part can include the basic operation methods of addition, subtraction, multiplication and division, the application of calculation rules and so on. In the part of comparative ability, it can include how to compare the size of two numbers and how to convert units.
3. Mathematical application: This aspect mainly covers the mathematical application involved in this unit, such as how to use mathematical knowledge to solve problems in real life and how to apply mathematical knowledge to practical problems. For example, how to calculate the total price when shopping, how to calculate the perimeter and area when measuring, etc.
