1. Explain the rules of the number-filling game to children: each row and column must have four numbers, 1, 2, 3 and 4, which cannot be repeated. Numbers in each row and column can only appear once. What are the numbers of A and B respectively?
2. Guide children to find the key starting point: first find out the row or column with the most numbers. Among these rows or columns, which row and column contains the space has three different numbers? (Rows or columns with only one number are not considered). You can fill in this blank first after confirmation.
How to learn mathematics in the second grade;
First, understand mathematical concepts.
In the second grade mathematics, children need to master some basic mathematical concepts, such as understanding, addition, subtraction, multiplication and division. First of all, make sure that children have a clear understanding of these concepts.
Through physical demonstration and picture display, children can understand abstract mathematical concepts. At the same time, children should be encouraged to consolidate their understanding of these concepts through practice. For example, let children make simple calculations in their daily lives, such as calculating the total price and dividing candy when shopping.
Second, cultivate logical thinking ability.
Grade two mathematics is not only to master mathematical concepts, but also to cultivate children's logical thinking ability. We can exercise children's logical thinking through some interesting games and activities. For example, organize children to play digital puzzles, so that they can learn to infer unknown results according to known conditions; Or let children do simple graphic splicing to cultivate their spatial imagination.
I used to worry about my children's study, and their academic performance was very poor. I want to improve my grades. I don't know how to help them. Until I saw the road class two months ago, my grades improved a lot after a while. My children like their study plans and guidance very much. As a parent, I am finally relieved and my children are very happy.
Third, pay attention to practical application.
Mathematics is a subject closely related to life. We should let children understand the importance of mathematics knowledge in real life, so as to stimulate their interest in learning mathematics.
For example, when learning multiplication, children can be guided to think about how to use multiplication to solve practical problems, such as calculating bus fares and calculating the number of building blocks. This will not only make children realize the practicality of mathematics, but also improve their interest in learning.
