First, the understanding of numbers
At the beginning of mathematics learning, we need to understand the concept of number first. In the first math test paper of the first grade of primary school, some topics related to digital understanding will also be involved. For example:
1. Fill in the blanks with numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,1,12,/kloc-.
2. Use "√" or "×" to indicate whether the number of items in the figure below is the same.
These topics are to examine students' knowledge and understanding of numbers. For the first question, we can observe the law of numbers and get the answers as 16, 17, 18,19,20. For the second question, we need to carefully observe the number of items in each graph, and then judge whether they are the same.
Second, addition and subtraction.
Knowing the number, we can begin to learn addition and subtraction. There will also be some topics related to addition and subtraction in the first volume of the mathematics test paper for the first grade of primary school. For example:
1. Fill in the blanks with numbers: 7+_ = 9, 9-_ = 6.
2. Fill in "+"or "-"in the following formula: 3 _ _ 4 _ _ 2 = 5, 8__6__5=3.
For these problems, we need to understand the basic principle and operation method of addition and subtraction first. For example, for the first topic, we can draw a conclusion by backward deduction. The first space is filled with "2" and the second space is filled with "3". For the second question, we need to judge whether to fill in "+"or "-"according to the numerical value in the formula, and then calculate.
Third, the arrangement and combination of numbers.
After learning addition and subtraction, you can begin to learn the permutation and combination of numbers. There will also be some topics related to the arrangement and combination of numbers in the first volume of the mathematics test paper for the first grade of primary school. For example:
1. Fill in the blanks with numbers: 2, 4, 6, _ _, _ _, 12.
Fill in the blanks with numbers: 1, 2, _ _, 4, 5, _ _, 7, _ _, 9.
For these topics, we need to infer the number of vacancies according to the size and law of numerical values. For example, in the first question, we can find that each number is the previous number plus 2, so the answer can be 8, 10. For the second question, we can find that there will be a vacancy every other number, so we can get the answers as 3, 6 and 8.
Four. Time and calculation
The first volume of the mathematics test paper for the first grade of primary school will also involve some topics related to time and calculation. For example:
1. Fill in the blanks with numbers: it's _ _ pm, and 1 hour is _ _ pm.
2. Calculation: 3+4=__, 5-2=__, 6×2=__, 8÷4=__.
For these topics, we need to understand the concept and calculation method of time. For example, for the first question, we need to know that it starts at 12 pm and ends at 8 pm, so we get 4 and 9. For the second question, we need to master the basic operation methods of addition, subtraction, multiplication and division, and then calculate.
The above are the contents and solving methods of the first volume (basic knowledge evaluation) of the mathematics test paper for the first grade of primary school. Through serious study and practice, I believe everyone can master the basic knowledge of mathematics and get good grades.
