1, each row has 10 numbers, and 10 rows (each column has 10 numbers and 10 columns).

2. The number on the right of two adjacent numbers in a row is larger than the number on the left 1.

3. The number below two adjacent numbers in the column is greater than the number above 10.

There are usually hundreds of tables in the textbooks of the first grade of primary school (learning factors and multiples, prime numbers (prime numbers) and composite numbers are also useful in the fifth grade), which is intended to let students know more clearly the arrangement order of numbers within 100 after they know the numbers within 100, which not only consolidates the numerical order of 100, but also can be used in tables.

Cultivate the skills of mathematical thinking logic;

1, doubt, stimulate children's thinking

Children are curious, questioning and eager to learn. According to this feature, when parents encounter problems related to mathematics in their lives, they should pay attention to guiding their children, give them opportunities to think about how to calculate, and fully mobilize their learning enthusiasm and active thinking.

2. Guide discovery and promote the creation of thinking space.

Thinking begins with finding problems, which is the starting point and one of the driving forces in the process of solving problems. After discovering the problem, we need to further understand the nature of the problem. Only by understanding the problem can our thinking activities have a certain direction.
