4.50 pieces 10 of gold beads are put in wooden cases.
5. "Bridge" made of thick paper.
Direct purpose
1. Add operation with colored beads.
2. The exchange will take place every 10.
Indirect purpose
1. Understand the concept of continuous addition.
2. Strengthen order training.
Activity prompt
1. Spread a piece of flannel on the table and put away the teaching AIDS.
2. Placement of beaded bar:
(1) Take out a proper amount of colored beaded sticks from the colored beaded stick box, randomly arrange them in a long string, cover them with wooden cases, and put them on the upper right of the flannel.
(2) Arrange the black and white beaded sticks in the order of 1 ~ 9 on the upper left of the flannel in a pyramid shape, cover the box cover and put them on the upper right.
(3) Place the golden beaded stick box next to the black and white beaded stick of 1 ~ 9.
3. Add operation of colored beads:
(1) After placing all kinds of beaded sticks, start counting colorful beaded dragons. Use the bridge to count one grain at a time from left to right. Don't count too fast.
(2) Every time it reaches "10", it is separated by a bridge, and the colored beaded combination on the left side of the bridge is replaced by a golden beaded strip; If a colored bead is divided into left and right parts by the bridge, the remaining colored bead on the right side of the bridge is replaced by the same number of black and white beads.
(3) Place the replaced colored beaded stick at the lower right of the flannel.
(4) Count again from the black and white beads.
(5) Repeat the above steps of exchanging beads every time it counts to "10", and put the exchanged black and white beads back in place.
(6) Complete the work of counting and exchanging beaded sticks in the same way, and finally get a new "long dragon" consisting of gold beaded sticks and black and white beaded sticks (if the unit number is "0", there is only gold beaded sticks).
(7) Let the children count the total number of gold beads and black and white beads and tell them, "This is the answer."
4. Check the calculation:
(1) Try to combine the colored beaded sticks placed at the lower right of the flannel into 10, which corresponds to the golden beaded stick 10 (in order to make up 10, you can open the colored beaded stick box and replace the colored beaded sticks on the flannel with the same amount of beaded sticks in the box).
(2) Take the remaining colored beaded sticks, corresponding to the black and white beaded sticks on the long dragon.
(3) If the number of colored beaded sticks that make up the "Long Dragon" is consistent with the number of golden beaded sticks (inlaid with black and white beaded beads) on the new "Long Dragon", the answer is correct; Otherwise, the answer is wrong.
(4) Tell children that this is "checking calculation".
Error correction check calculation.
Extension change
Paper exercise: Let the children record the process of long queues in words.
Expert tips
1. The prerequisites for children to carry out this activity are: having decimal experience; Know the colored and black and white beaded sticks.
2. The replaced black and white beaded strips should be put back in place in time to facilitate inspection.
Montessori Mathematics Teaching Plan for Middle School Parents' Open Day —— Understanding Adjacent Numbers
Activity objectives:
1. Understand the meaning of adjacent numbers within 5, and perceive the relationship of greater than 1 less than 1.
2. It can express the adjacent number of numbers within 5 to improve children's thinking ability.
Activity preparation:
Colored beads, digital puzzles, digital chest ornaments 1-5, cards for small houses, 5 for each person.
Activity flow:
1. Let the teacher play the piano and let the children follow the music.
2. Online game: "Good Friends Hug"
In the first round, the teacher asked six children to clap their hands and read nursery rhymes: one, two, three, two people hug. (Find a good friend to hug next to) Repeat twice. In the second round, teachers can invite 9 or 12 people to play together, clap their hands and read children's songs: one, two, three, three hugs. (Find three people to hold together) Repeat twice.
3. Go back to your seat.
(1) The teacher shows the flower-shaped digital brooch 1-5 to let the children know.
(2) game: flowers open the door.
Game flow: The teacher first invites three children to play a game and gives them three digital brooches 1-3 in turn, standing in a row. The teacher said 1 Xiaohua opened the door, and the child with the digital badge 1 made the action of opening the door and took a step forward. The teacher asked the children again, "What is the number of the little flower next to Xiaohua/kloc-0?" The child replied: "No.2, they are the closest." The teacher told the children that 1 and 2 are two adjacent numbers. Similarly, please ask No.3 Xiaohua, No.3 Xiaohua will open the door and take a step forward. Guide the children to say that 2 and 3 are adjacent numbers. (that is, the nearest two numbers are adjacent numbers, and there are two adjacent numbers to guide children to say 2, 1 and 3).
(3) Teachers show colored beads for children to observe, and then answer the corresponding question: "1 How much more than 2? (2 ratio 1 big) How much is 2 smaller than 3? (2 is 1 less than 3) 2 How many good friends do you have? (2 have two good friends) What is it? (1 and 3).
(4) Teacher's summary: Like this, every number above 1 has two good friends, one is less 1 and the other is more 1. (that is, these two numbers are the two closest numbers to it, that is, its neighbors. )
(5) The teacher tells a story and asks the children to put the house number on grandma cat's house. First, the teacher gave the children digital puzzles and cards of small houses, and asked them to take out the cards and digital puzzles of small houses from small bags. Then they put the bags behind the small chairs, put the digital cards on the small houses in sequence, and put a house number on each house. After the operation is completed, let the children observe and the teacher ask questions, and guide the children to say the adjacent numbers of 1, 2, 3, 4 and 5 respectively.
4. Exchange summary and organize school tools.
5. The game "Find Friends".
Teachers can divide the class into five groups to play games, and bring digital brooches for children to remember numbers. At the beginning of the game, the teacher can say a number at will. If the teacher says "4", please ask the child with the number badge 4 to pull two children who are more than 4 1 and less than 4 1 to stand out together (that is, list two adjacent numbers of 4), see who is the fastest and most accurate, give praise or reward, and report their two adjacent numbers (5 or 3) respectively. Finally, suppose that the neighboring numbers of 4 are 3 and 5. The game can be played repeatedly.
Effect analysis and reflection:
The activity was quite successful. Most children perform well in classroom routine, can understand the meaning of adjacent numbers, perceive the relationship between greater than 1 less than 1, and can quickly answer adjacent numbers within 5. However, after feedback from parents, some children's classroom routines are not ideal, and they have not fully achieved the goals of this activity, and their mastery is not ideal. This is also the detail that I neglected in this activity, so I will pay special attention to these details in the next activity to make the activity goal more clear. In every teaching activity in the future, I will take good care of all the children and satisfy my parents.
Main characteristics of Montessori teaching method
Taking children as the center is to overthrow the past educational concept of taking adults as the center and establish the educational goal of taking children's life as the center of activities. Montessori advocates child-centered, traditional classroom-centered, book-centered and teacher-centered. Now, the reform advocates three new centers, namely, children-centered, activity-centered and experience-centered.
Education without teaching. Montessori opposes spoon-feeding teaching and advocates starting with daily training, with a good learning environment and rich education, allowing children to learn spontaneously and educate themselves.
Grasp the sensitive period of children. Montessori teaching method especially emphasizes the sensitive period of children, so that children can master the best learning period along the sensitive period. You can get the maximum learning effect.
Teachers play the role of assistance and guidance. Teachers' job is to observe children's inner needs, design environment for them, demonstrate teaching AIDS and prepare for learning. It is also necessary to educate children's individual differences and inspire and guide them in time. This kind of assistance and inspiration can make the relationship between teachers and students friendly and let children learn naturally and happily.
Pay attention to the cultivation of wisdom and character. The essence and significance of early childhood education is mainly to help children grow up perfectly. Therefore, Montessori believes that the purpose of early childhood education is not only to prepare for entering primary school. In the past, we said that early childhood education was to lay the foundation for entering primary school. Now, after research, we think this goal is too simple and short-sighted. Montessori believes that the essence and significance of education is to prepare for a perfect life and lay the foundation. Not only to prepare for primary school, but to lay the foundation of character and wisdom for children's life. Cultivate children's good habits of lifelong learning from an early age.
Respect the growth rhythm of children. Montessori education has no timetable, regardless of class time. He advocates that children should follow their inner needs, choose teaching AIDS that suit them and work at their own free speed. If a child's concentration is interrupted, he will develop a sloppy habit. If children's needs are respected and allowed to work longer hours, their concentration and persistence will naturally be cultivated. Montessori education does not advocate interrupting children's work. If he continues to work according to his own needs, neither parents nor teachers should interrupt her. When her body and mind can't support her, she loses interest and will naturally stop working.
Mixed age teaching. Children of different ages are in the same class, and they can teach the big and teach the small, and the primary school is big. We can imitate each other, learn from each other, appreciate each other, tolerate each other and get along well. It can also cultivate children's good social behavior of helping others.
Rich teaching materials and teaching AIDS. There are as many as 349 kinds of Montessori teaching AIDS, which is a major feature of Montessori teaching materials. We often call it a teaching aid, but it is actually a Montessori textbook. Its teaching materials have different carriers. Different from our textbooks, Montessori concretized the textbooks. This textbook is very rich. In nature and life, there are many living textbooks. Different from the textbook in the classroom, this textbook is not used by teachers to teach students, but is the material for children to work. This is how children repeatedly operate textbooks from the simple to the deep, and he constantly achieves the goal of self-education. We can say that the rich teaching materials are Montessori's teaching AIDS and can also be said to be a supplement to the teaching materials. Textbooks have become teaching AIDS.
Exclude the reward and punishment system. Because the traditional reward and punishment system is a means for adults to control children, and it is a way to control children's behavior by using external forces. After long-term observation, Montessori found that rewards and punishments are not only useless, but also destroy the budding self-esteem of children, not only failing to help children improve their behavior. Will mislead children's values. Therefore, Montessori advocates abolishing the reward and punishment system, allowing children to develop freely and cultivate self-control ability.
The emergence of teaching achievements. Montessori teaching method is to cultivate children through step by step and self-education, so it is not easy to see the learning effect in the short term. But the teaching results are often presented with explosive force. Suddenly showing the growth of the child's mind. Training children according to Montessori's educational methods can benefit him from primary school, junior high school and senior high school. After high school, children accepted the knowledge of physics and chemistry quite quickly, and then appeared. For example, the number of mathematical gold beads ranges from 10 to 100 to 1000. He used various methods to stimulate children to master mathematical concepts and four operations, such as banking games and currency exchange, instead of teaching him how many words he knew and how much mathematics he knew. So it has the ability to suddenly appear. After going to school, his ability to accept is particularly fast and he can understand immediately. Therefore, the teaching effect cannot appear immediately. But it is helpful for his lifelong learning.
