8' s addition teaching plan contains reflection on the teaching goal of 1;
1, the learning number is the addition of 8. I can look at the picture or calculate the formula according to the item.
2. Further understand the meaning of plus sign and equal sign.
3. Experience the fun of playing the same game.
4. Cultivate children's habit of speaking while operating.
5. Understand the application of numbers in daily life, and preliminarily understand the relationship between numbers and people's lives.
Teaching preparation:
1, teaching aid:
(1) Picture: 8 birds, 8 kittens, 8 rabbits and 8 peacocks.
(2) A picture of a forest
2. School tools: some small snowflakes
Teaching process:
First, the teacher led the children to do finger exercises to concentrate their attention.
Teacher: "Children! (hey! ) Shall we do finger exercises together? (good) stretch out a pair of small hands and do finger movements together; Open your fist and relax. One, two, three, four, five, six, seven, eight, two, two, three, four, five, six, seven, eight, five, six, seven, six, seven, eight; Swing left and right with open hands, three, two, three, four, five, six, seven, eight, four, two, three, four, five, six, seven, eight, four, five, five, six, seven, eight, eight.
Second, put small snowflakes and review the composition of numbers within 8.
1, the teacher says the number within 8, and asks the children to take out the corresponding small snowflakes in the basket and divide them into two parts. (children's operation)
2. Ask some children to get up and tell everyone how they got it, see if he got it right, and give encouragement to those who got it right. At the same time, the teacher will show the children's score results on the blackboard by means of composition.
Please read these compositions to all the children.
4. The teacher told the children that in order not to miss, we should master a rule when dividing: divide according to the method of one less on the left and one more on the right, so that it is not easy to miss, for example, divide 8 into 1 and 7, and divide it according to the rule of 1 on the left and 1 on the right, that is, 8 can be divided into 2 and 6, 3 and 5.
The teacher and many small animals gathered in the forest to celebrate "6". 1 "Teach children to learn 8 on Children's Day. Teacher Jia Fa showed pictures of the forest and told the children, "Children, this is a beautiful big forest. Today the forest is very lively!"! Many small animals gather here to celebrate Children's Day. Are they going to perform a program for the children to celebrate the festival? (happy)
1. Let's watch the first program "Birds Singing" brought by small animals.
(1) shows 1 bird, seven birds fly in. Q * * * How many birds are singing? Q: How did you work it out? (subtraction) formula: 1+7 = 8. According to the exchange law of addition, the number of two addends remains the same. Who can list another formula? (Children formula: 7+ 1 = 8. )
(2) Please read the formula1+7 = 8,7+1= 8.
Please watch the second program "Cats Catch Mice" brought by small animals to children.
(1) Two cats catch mice, and six cats catch mice. Q: How many cats are performing Cats Catch Mice on the stage now? (8) How did you work it out? (Addition) Formula: 2+6=8. After seeing this formula, can you list another formula? (Children's formula: 6+2=8)
(2) Please read formulas 2+6=8 and 6+2=8.
The following is a program brought to us by the lovely rabbit-the song performance "Little Rabbit Darling".
(1) Show three rabbits, and then five rabbits run away. Q * * * How many rabbits are performing? (8) How did you work it out? Formula: 3+5=8. Can you list another formula? Q: What does 5 mean here? 3 What does it mean here? How about eight o'clock?
(2) All children read the formulas 3+5=8, 5+3=8.
The beautiful peacock heard that Children's Day is coming, and it has arrived. It will also perform programs for children. Please watch the program "Proud as a Peacock and Colorful Clouds" brought by the little peacock to children.
(1) Show four little peacocks to act as proud as peacocks, and then four little peacocks come. How many little peacocks are performing here now? (8) What method did you use to calculate it? How much is (addition) 8? (4+4=8) What do these numbers mean here? (Answer with children) (Read the formula together)
(2) Let children read the addition formula with the number 8.
Fourth, the game of "making up numbers", review the addition method of the combined number less than 8: the teacher shows a number, so that children can read it carefully, then the teacher says a number, and the children also say a number, so that the teacher can say this number, and the children say that the added number is the number shown by the teacher. After showing the number 8, the teacher said, "I'll give it to you 1. How much will you give? " The child said, "You give 1, I give 7, and the teacher: 1+7=? Children: 1+7=8 (repeated game)
Fifth, the teacher summarizes the activities and ends them.
Activity reflection:
The increase of learning 8 is the content of the big class next semester. As we all know, mathematics itself has a strong logic, which easily makes children feel that teaching is boring, thus affecting their autonomy and enthusiasm in learning. It is clearly pointed out in the outline that the goal of mathematics education is to "feel the quantitative relationship of things from life and games and experience the importance and interest of mathematics." Under the guidance of this spirit, I conceived this mathematical activity, which is the connection between abstract concepts and concrete objects. It not only transfers general knowledge to specific things, strengthens the horizontal connection of knowledge and expands the cognitive surface, but also is extremely beneficial to developing children's thinking, cultivating the accuracy of thinking and stimulating children's interest in learning mathematics.
First, the game import: "Guess the Fruit"
Today, the animal kingdom will hold an animal sports meeting, and I want to invite children to participate. Would you like to? Children love it, wow! It turned out that the small animals also prepared some fruits for us. Look! Here are two baskets of fruit, one basket of apples and one basket of pears. The total number of these two baskets of fruit is 8. A basket of apples, a basket of pears, 1 pear How many apples are there? Here, I randomly ask questions in the form of collective answers or individual answers: How did you guess? Guide the children to review the division and combination of 8. Children already have the composition of 8 and the basis of addition and subtraction within 7, and they can basically answer it.
Second, the core process: learning the addition of 8.
This lesson is not difficult, but we must combine the operation with illustrations, so that children can have an intuitive understanding, give full play to their initiative, internalize new knowledge in interesting activities, let children experience and feel the source of knowledge, cultivate their ability to solve problems, experience the fun of mathematics and master the methods of understanding and learning. Walking, it came to a meadow. Let's see what it sees. It turns out that the pig is going to participate in the animal sports meeting. Walking, it came to a meadow. Let's see what it sees. (Put pictures in turn), there are several, and then there are several. How many are there now? Here, children are asked to look at the picture and say the corresponding formula and the meaning of the numbers in the formula.
Third, business activities: shooting pigs
The sports meeting is about to begin. The pig came to the basketball stadium to take part in the shooting competition. What's on its basketball? What's in the basket? Do you know what this means? (First, calculate the number of ingredients in each basket and connect the baskets with pig basketball thread. ) through various games, guide children to look at pictures and list formulas, learn to use the composition of 8 and decompose and calculate the addition of 8, which needs attention. Many children connect the pictures like a spider's web, and repeatedly emphasize that the lines can't be mixed together, so we must pay attention to the direction of the lines, otherwise our own lines will be mixed up.
After this class, I also have some ideas:
1. How to improve the effectiveness of teachers' questioning in class? Why do children always have to say hello several times before they can answer?
My thoughts are as follows:
1, in the process of mathematics teaching, teachers should be good at asking questions, guide children to think about problems from shallow to deep, solve problems step by step, and stimulate children's interest in learning mathematics. Questioning should embody the principles of hierarchy and development, ask questions in layers according to children's existing experience, gradually deepen the level, and reflect effective teaching to promote children's development. For example, in the mathematical activity of "leaf classification", the teacher first asked: "What should I do if the yellow leaves and green leaves want to go home? Please help them find their own home. " On the basis of children's color classification, ask another question: "In Huang Ye's family, they should live together according to their shapes. Can you help him score? " "After the children have sorted the leaves according to their shapes. The teacher asked again, "Can you divide the leaves by size?" So the children were classified for the third time. Through teachers' questioning at different levels, children's activities have different levels of goals, which leads to children's constant attempts to explore, which not only meets the needs of children at different levels, but also makes children make continuous progress on the original basis, reflecting the initiative of learning. 2. Start with activities to develop children's attention.
2. Mathematics comes from life and is closely related to life. The problem of knowledge level allows children to recall what they have learned and explore and discover on the basis of existing experience. For example, in the math activity "Know the clock", the teacher showed the clock face without a needle and asked the children, "Please look carefully, what is missing from the clock face?" Let children recall the main characteristics of the clock they see in their lives, urge them to recall and think, and let them tap the existing experience in life and mobilize the existing experience. On this basis, children can explore and discover, improve their experience and further understand the meaning of the three needles.
The additional lesson plan of 8 contains the activity objectives of reflection 2:
1, understand the meaning of 8 addition through teaching aid demonstration, teachers' and children's activities and oral addition exercises.
2. Cultivate the accuracy, flexibility and agility of children's calculations.
3. Understand the interchangeability and mutual irregularity of the addition of 8.
4. Cultivate children's ability to observe, judge and operate.
5. Cultivate children's spirit of trying and develop children's agility and logic of thinking.
Emphasis and difficulty in teaching:
1, key point: let children strengthen the accuracy of addition in exercise 8.
2. Difficulties: Exercise children's thinking flexibility and discrimination.
Activity preparation:
1, wall chart, snowflake, homework paper, map.
2, 8 digital headdress, music game tape.
Activity flow:
First, the beginning part:
Organizing teaching, the teacher walked into the classroom wearing a digital headdress of 8. Hello, children, the teacher brought it today.
Learn digital doll 8 with us, concentrate children's attention and observation, and stimulate their interest in learning.
Second, the basic part:
(1) Review the division of 8 in the form of duet, first according to the complementary relationship, and then according to the exchange relationship.
Teacher: Let me ask you something, little friend. What number can 8 be divided by 1 and?
Child: Teacher Liu told you that 8 can be divided into 1 and 7. ...
Teacher: Let me ask you something, son. 8 How many kinds of division are there?
Child: Teacher Liu told you that 8 has seven divisors.
(B) learning the addition of 8
1, the teacher shows a wall chart for children to observe, and guides children to list addition formulas according to the size, color and shape of flowers:
There are 1 yellow flower and 7 red flowers on the picture. How many flowers are there in a * * *?
1+7=8
There are two big flowers in Kobanawa in the picture. How many flowers are there in a * * *?
2+6=8
There are three round flowers, five oval flowers and one * * *. How many flowers are there?
3+5=8
There are four orchids and four purple flowers in the picture. How many flowers are there in a * * *?
4+4=8
2. Gymnastics
Give each child 8 snowflakes, let the children count the snowflakes, and fill in the corresponding numbers on the homework paper.
3. Teachers tour to guide children's operation, reward good children's maps, and strengthen guidance for poor children.
4. Game: Find friends
The teacher gave each child a digital headdress. When children think of music, they look for numbers that add up to 8 and become good friends. This game can be played by exchanging headdresses.
5. Guide children to observe things around and in the classroom. Together, it is the number 8. After returning home, they can also practice arithmetic, such as sugar, apples, biscuits, toys and so on.
Third, the last part:
The teacher comments on the class situation, praises the good children, guides and encourages the poor children to finish class.
Activity reflection:
In the future math teaching activities, I will use games more, because children are most interested in games and can attract them most. The form of games can make children more interested in math activities, stimulate their enthusiasm and initiative in learning, and form a good habit of loving brains and hands-on.
