The best way to teach children adjacent numbers

1, starting from the whole, let children understand the shallow meaning of the adjacent numbers in the sequence 1 to 10.

First, explain the concept of neighborhood in children's language. The teacher shows 10 digital dolls (which can be made into finger pairs), and asks children to arrange them in order from small to large and explain why they are so arranged, so as to review the relationship between 10 and 1. The teacher manipulated finger 2 and imitated it. "I am No.2, and my good friends are 1 in front and 3/in the back."

2, starting from the individual, find out the regularity.

"Who is your best friend?" "1 and 3" "Why are 1 and 3 good friends of 2?" "Because 1 comes before 2 and 3 comes after 2." Then why is 1 ahead of 2? "Oh, the teacher found a secret. A number of 1 less than 2 is a good friend of 2.

Is it the same with 3' s good friends? "Guide children to discover and verify that 1 a number less than 3 is a good friend of 3. Then, prove the good friends of 4, 5, 6, 7, 8 and 9 one by one.

3. Guide children to put the law of individual verification back into the whole and draw a conclusion.

Guide children to say a number of good friends, one less than it, one more. In this process of guiding discovery, children's reaction and reasoning ability are not very good, and teachers need great patience. Because of this foundation, children will learn faster and faster.

4. On the basis of children's understanding of adjacent numbers, learn step by step.

Learn the numbers within 5 and adjacent numbers first. Practice and consolidate through various forms of games. The difficulty of the game can be gradually increased. For example, "Two friends come together" is put on the child's head, and one child says, "I am the number X, and my two friends come together." His two digital friends quickly stood beside him. After you are familiar with this game, you can play the game of "finding friends", that is, a digital doll looks for his two friends.

5. Practice in the opposite direction.

Children can practice in the opposite direction after they are familiar with neighbors. For example, 1 and 3 have the same friend. Whose good friends are 1 and 3. Exercise children's logical thinking and let them "change quickly". "
