1, we need to understand what is continuous increase and continuous decrease. Addition and subtraction are two basic mathematical operations. Addition refers to adding several numbers together, and subtraction refers to subtracting several numbers from one number. For numbers within 10, we can start with 1 and calculate to 10.
For example, we can choose three hyphens: 1, 2, 3. We can add and subtract these three numbers.
Jia Lian: 1+2+3=6.
Even numbers decrease: 3-2- 1=0.
Through this example, children can understand how continuous addition works and how to use it to solve practical problems. At the same time, they can also learn how continuous reduction is carried out and how to use continuous reduction to solve practical problems.
2. We can also use this example to help children better understand the relationship between numbers. For example, through observation, it can be found that the sum of 1+2+3 is equal to 6, while the difference of 3-2- 1 is equal to 0. This can help children better understand the relationship between numbers and how to use these relationships to solve practical problems.
/kloc-learning method of three numbers within 0/0;
1, mastering numbers and operations: first, let children master numbers and addition and subtraction operations within 10. This includes being able to count accurately and quickly, recognizing the size and order of numbers, and mastering basic addition and subtraction operations.
2. Understand the concept of addition and subtraction: let children understand the concept of addition and subtraction. Addition refers to adding several numbers together, and subtraction refers to subtracting several numbers from one number. Examples or stories can be used to help children understand these two concepts.
3. Learn the operation order of addition and subtraction: let the children know the operation order of addition and subtraction. Continuous addition can start with the first number, and then add the second and third numbers in turn; Continuous subtraction can start with the first number and then subtract the second and third numbers in turn.
4. Practice through examples or games: You can provide children with some examples or games so that they can master the operation methods of addition and subtraction through practice. For example, children can be given some digital cards, and they can choose three numbers to add and subtract.
5. Encourage children to actively explore and learn: Encourage children to actively explore and learn, so that children can gradually master the addition and subtraction methods of three numbers within 10 in practice. At the same time, we should give children affirmation and guidance in time to help them build self-confidence and interest in learning.
6. Establish good study habits and attitudes: Help children establish good study habits and attitudes. In the process of learning, children should be patient and focused. Don't give up easily when you encounter difficulties. Think positively and seek solutions. At the same time, let children understand the importance of learning and encourage them to actively learn and explore new knowledge.
