The teaching goal of 1 in the teaching plan of mathematics adjacency number in middle class;
1, know the concept of adjacent number, and master the adjacent number of each number within 5.
2. Understand and tell the relationship between adjacent numbers greater than 1 or less than 1.
3. Cultivate children's comparative ability and thinking flexibility.
4. Cultivate children's comparative judgment ability.
5. Develop children's logical thinking ability.
Teaching preparation:
1, "Neighborhood within 5" courseware, children's operation exercises.
2. 1-5 digital card with background music.
Teaching emphases and difficulties:
1, teaching focus: understand the concept of adjacent number and master the adjacent number of numbers within 5.
2. Teaching difficulties: Understand and be able to tell the relationship between adjacent numbers greater than 1 or less than 1.
Teaching methods and means:
Scene setting method, game method and operation method.
Teaching process:
First, the beginning part:
Set the scene to understand the "neighbor" relationship.
1, Teacher: The animal kingdom is very busy today because they are moving to a new home. How many new houses are there? Which animals are moving?
Let the children know who are the small animals and who are their neighbors by asking questions.
Second, the basic part:
(1) Learn the adjacent numbers within 5 to understand the relationship between adjacent numbers.
1, Teacher: It's getting dark. It's time for the animals to have a rest. Listen, who is talking? Oh! It turns out that the digital baby is discussing the problem. Digital Baby 2 said, "I am 2, Digital Baby 1 and Digital Baby 3 are my good neighbors, and we are adjacent numbers. I will call it an adjacent number, and the adjacent numbers of 2 are 1 and 3. " Ask the children to find the adjacent numbers of other numbers.
2. Teacher: Those digital babies have become creative babies. Look at two creative babies. How much is the idea baby more than 1 idea baby, and how much is the idea baby less than three idea babies? Read it together: 2 is greater than 1 and 2 is less than 3. (Adjacent numbering of methods 3 and 4)
(2) the game "find friends".
The teacher casually held up a digital card smaller than 5. When the teacher said, "find a friend, find two good friends, I am digital baby 2, what is my neighbor's number?" Children with the numbers 1 and 3 quickly raise them, and the game can be repeated.
(3) Organize children to complete the operation exercise: "Neighboring friends".
Third, the last part:
1, evaluation of children's operation exercises.
2. Check homework for mom and dad.
Activity reflection:
In the process of activities, firstly, the scene of "animals moving" is used to help children understand the "neighborhood relationship", review the arrangement of numbers and the relationship between numbers, lay the foundation for children to understand the concept of "neighborhood" and the relationship between neighbors in the future, and follow the gradual law of children's mathematics learning from easy to difficult and from simple to complex. Among them, learning the adjacent number of 2 is an important process. In this process, we can understand what the adjacent number is and its relationship, thus paving the way for exploring the adjacent numbers of 3, 4 and 5. In the whole process, let the children be in a state of active exploration and guide them to draw their own conclusions. However, in the process of breaking through the difficulties, although children can complete the practice of related neighbors in the previous game operation, it is difficult for children to understand the seemingly simple content of neighbor relations. In order to let children fully understand the relationship between adjacent numbers in the new teaching process, teachers' guidance is needed.
The Design Background of Activity 2 in the Teaching Plan of Neighborhood Solitaire in Middle School Mathematics
Children's knowledge coverage and cognitive level may be different due to regional differences, and the rural children we face are even different from those in municipalities directly under the central government. Therefore, in view of the individual situation of rural children, I focus on teaching in real life, and use my neighbors in life to teach neighbors, so that teaching activities can be carried out more effectively.
moving target
1. Learn the adjacent numbers and understand the relationship between them.
2. Through the study of neighbors, I know that neighbors should help each other and develop good behavior qualities of uniting others and helping others.
3. Stimulate children's interest in learning.
4. Cultivate children's spirit of trying and develop children's agility and logic of thinking.
5. Develop children's logical thinking ability.
Teaching emphases and difficulties
Master the adjacent number and know that the difference between adjacent numbers is 1.
Activities to be prepared
1, digital card
2. Family cards for small animals
Activity process
First, the teacher introduced
1, children, each of our children will have neighbors at home, so tell us who your neighbors are?
2. Enter the learning of adjacent numbers through the teacher's questions.
Second, learn the neighbor number.
1, the teacher shows the digital card of 1 ~ 10 and the children read it out.
Please look at the children. Like our neighbors, these numbers are adjacent to each other. So who do they care about and who are their neighbors? Guide the children to say the adjacent numbers of each number.
3. Let the children carefully observe the numbers from 1 to 10, and know through the teacher's guidance that the relationship between adjacent numbers is the difference of 1.
Children finish the content of the textbook under the guidance of the teacher.
Third, game activities.
1, the child is looking for a neighbor with a digital card.
2. Small animals look for neighbors.
Fourth, the teacher summary:
Today, all our children have found neighbors, which is really great! So what should you do to become a neighbor? I want to be a good boy who helps each other, helps others and unites others!
Teaching reflection:
1. In this activity, the children mastered the adjacent numbers and their relationship, and learned knowledge in the game activities in a pleasant atmosphere. The effect is better than expected.
2. In teaching activities, some children can't understand the relationship between adjacent numbers, so we should pay attention to the acceptance ability of individual children in teaching.
3. Learn about neighbors through activities. If we can add some addition and subtraction exercises (plus 1, minus 1) to assist the learning of adjacent numbers.
4. In the future education and teaching activities, especially in game activities, teachers should pay attention to their own language expression, so as to understand what you are saying more thoroughly and how to fulfill your requirements, so as to better complete the activities.
