7 large class subtraction teaching plan 1

Teaching objectives:

Because it is an open class, we should also increase our interest in the class while giving lectures, thus greatly improving our understanding of simple addition and subtraction calculation.

Teaching preparation:

Teachers can prepare multiple groups of cards, all of which are addition and subtraction calculations, and even in order to increase the difficulty, they can add and subtract mixed calculations to add points to this class.

Teaching process:

1. First of all, teachers can give students some simple addition problems on the blackboard and let them answer them first, which will help improve the classroom atmosphere and increase children's self-confidence.

Then the teacher can put the cards on the table and divide the students in the big class into four groups. The first group will take the lead in answering questions. At this time, the students in the fourth group are responsible for drawing questions for the students in the first group. By analogy, the game can be played fairly, and the team that answers correctly can get a reward of one point. The more correct answers, the higher the score.

At the end of this class, the teacher will add up the scores of each group, or let the children calculate the scores of their own groups. For the team with the best performance and the highest score, the teacher can give rewards on appropriate stationery pencils, which can motivate each student to bring greater promotion and improvement in the play-off.

End:

The effective application of simple addition and subtraction competition is beneficial to the progress and development of accuracy. The effective implementation of this interesting teaching activity is believed to enhance children's efficiency in mathematics curriculum and calculation.

7 2 large class subtraction teaching plan

Activity objectives:

1. Understand the meaning of haircut.

2. Master the hairstyle of 5 and know "-".

3. Experience the fun of math games.

4. Cultivate children's ability to recognize numbers.

5. Let the children judge the quantity correctly.

Activity preparation:

"-"card, 1-5 digital card, small animal headdress

Each person has an operation card and a toy card.

Activity flow:

1. Review the decomposition of 5, and understand the relationship between quantity and quantity through clapping games.

Teacher: Let me ask you, little friend, how much can 5 be?

Child: Teacher Yu told you that 5 can be divided into 3 and 2.

2. Create a scene, put a digital card, and use the corresponding relationship between number and quantity to understand the meaning of haircut.

Teacher: It's a beautiful day today. Bear invited his good friend to his house. Bear prepared a lot of delicious food, five bones, five bundles of feelings, five carrots and five bugs. His good friends, dog, lamb, rabbit and chicken, were so happy when they came. They ate so delicious. Let's see how much they ate.

Teacher: The bear brought five carrots, which are represented by the number 5. The rabbit ate two carrots, which are indicated by the number 2. How many carrots are left? The remaining three are represented by the number 3, and 5-2=3.

Understand that cutting your hair means reducing the number after you lose it.

3. Play games and let children play small animals. Count the five kinds of food on the plate in front of you. How many did you eat? How many are left?

4. Subtraction calculation exercise. Children are free to work in pairs. Children in each group take five toys and guess. After the child B closes his eyes, the child's family takes some toys, and asks the child B to calculate how many toys the child A takes for a haircut, and mark the formula with a digital card.

Suggestion: In order to consolidate and master the haircut within 5 hours, the teacher can provide colorful toys for the children in the activity area after the activity, so as to stimulate the children's desire for operation and interest in participating in the activity.

Activity reflection:

The math activity "bear treat" introduces the story of Bear Treat, and takes children into the matching learning of numbers, points and objects in a gamification and life-oriented way. Because the teaching AIDS and learning tools were fully prepared before class, the class went smoothly. The children listened carefully, learned well, and of course finished their homework well. The activity flow is like this. Combined with the arrival of two festivals, I released the protagonist "Little Bear" and told the children, "In order to celebrate the arrival of the festival, Little Bear invited his good friend to be a guest like Mrs. Mouse today (I have learned from the early reading of" Mrs. Mouse Treat "). Look! How many guests did Bear invite today? " Then I show these animals one by one. Let children learn to be heroic bears. Welcome friends. These are familiar animal friends, such as cats, dogs, chickens and monkeys. Children like them very much. Let the children count individually and collectively. Today, the bear invited several guests, and the children quickly said "six guests". Then I asked some children to come up and look for the number 6 card and the number 6 dot card.

Step two, invite guests to dinner. According to the food prepared by Little Bear for his friends, count your hands. For example, 1, 2, 3, 4 * * There are four bugs. Say, learn to express yourself in complete sentences, for example, the bear prepared two carrots for the rabbit, which can be represented by the number 2. Look for and find the corresponding digital card from a pile of digital cards, such as the number 2 or a point card with two points. Take it, find the corresponding card and put it in the place where the animals and food match. In the form of individual, collective and pairwise cooperation, let the children match the physical quantities with the numbers and points in the bear's treat scene, correct their mistakes, learn from each other and experience happiness with the help of their peers.

The third link is to let the children operate on the third page of the activity material "Mathematics". I remind and inspire some children with weak ability in time, and guide them while patrolling. The children's completion is very good.

"Mathematics comes from life and is applied to life." Children use what they have learned in gamification scenes and consolidate it to serve their lives. Mathematics knowledge is based on life experience, so that children can further develop on the basis of the original knowledge and experience (near the development zone), which is more in line with children's development law and learning characteristics. Teachers' teaching methods should emphasize "interest" to arouse children's interest. Life-oriented and game-oriented methods are more suitable for children, easy for children to accept, and stimulate children's interest in knowledge and desire for operation. At the same time, I also found that the ability of individual children is really weak, especially the newly arrived children. It is necessary to communicate with parents more so that children can adapt to learning as soon as possible.

7 3 large class subtraction teaching plan

moving target

1, learn the relationship between quantities and understand the meaning of addition and subtraction.

2. Further practice the addition and subtraction of 9.

3. Develop children's observation and spatial imagination.

4. Stimulate children's interest in learning.

Activities to be prepared

1, each child has a set of 1-9 digital cards, ten, one, =, headdresses of related animals.

2. The teacher prepares a magnet teaching aid.

Activity process

First, stimulate children's interest.

1. The teacher brought nine toys for the children to count.

2. Let the children say 9 points.

Second, group activities.

1. What graphic baby did the teacher bring you? Show the triangle (red and blue) and ask the children to say the addition formula.

The teacher is asking: how many triangles are left after subtracting 1 from 9 triangles?

How to write the formula? (Book: 9- 1=8)

Eight out of nine baby triangles, how many are left?

2. Show Apple graphics.

Children, what did the teacher bring? (7 red apples, 2 purple apples) One * * *, how many? How to calculate? How to write the addition formula? (Book: 7+2) You can also write the addition formula (2+7).

* * * 9 children's apples and 2 children's apples. How many apples are left? How to write formula 9-2=7?

Nine apples were given to seven children. How many apples are left? 9-7=2。

Iii. Business activities:

1, the first ball, six green balls and three orange balls-how many are there? How to work out the formula: 6+3=93+6=99-3=69-6=3?

2, operation 2 Show the pear-shaped picture for the child to say and then put out the formula: 5+4=94+5=99-5=49-4=5.

Fourth, game animals find homes.

Rules of the game; Children with animal headdresses are counted and then find a home. The rest of the children said, "xx animal, where is your home?" The little animal replied, "My home is here".

Self-reflection:

Knowing the number is the premise of calculation, which in turn can deepen the understanding and understanding of the concept of logarithm. The two are closely related. This activity organically links the identification and calculation of numbers within 10 through the composition of numbers. For every number within 10, let children gradually form the concept of number, master the composition and decomposition of number, and then achieve correct calculation. The child has learned the addition and subtraction of numbers within 10, but he doesn't quite understand the meaning of each number. How much is 1 plus 8 in this activity? Make them understand how each natural number is formed and its relationship with the previous numbers, and finally consolidate their application of the formula through pendulum. Not only deepen children's composition, decomposition and operation within 10.

On the way to treasure hunt, the teacher put the addition and subtraction formula of 3, and divided all the children into two groups to compete. Each group of children can finish the calculation and find the treasure first, and which group wins.

1+2=3 2+ 1=3 3+0=3

3— 1=2 3-2= 1 3—0=3

Teaching reflection

As a child who just came to preschool from kindergarten, they are full of curiosity about everything and can't concentrate. The classroom process is a boring process, so I design it according to the needs of students and the cultivation of their acceptance ability to make the whole classroom active. This is a relatively successful class. After the teaching, I made the following reflections: preschool children's attention duration is short, and it is their nature to be active. What they like best are games and activities. For children who are good at thinking in images, math activities are even more boring. How to stimulate students' interest in learning mathematics and improve learning efficiency? Considering the characteristics of mathematics itself and the age characteristics of children, I have taken the following measures to teach.

First, the use of game activities, a class time is very long, children are active, can not sit still for a long time. I inserted some games in the classroom, which greatly improved the teaching quality.

Second, arouse children's enthusiasm in the competition. Children have strong self-esteem and love to show themselves. In the group, they can win the red flag through competition, which makes them psychologically satisfied, thus mobilizing the enthusiasm of the children.

I will constantly sum up good teaching methods, really apply what I have learned to the classroom, and constantly improve the quality of teaching.

Class 7 Part 5 Subtraction Teaching Plan

Activity objectives:

1. Through observation and operation, the addition of 8 can be calculated correctly.

2. Cultivate interest in learning in lively scenes and games, and enhance the spirit of cooperation and active exploration.

3. Improve observation ability, language expression ability, hands-on ability and the ability to solve problems by applying mathematics initially.

4. Let children understand simple mathematics.

5. Understand the application of numbers in daily life, and preliminarily understand the relationship between numbers and people's lives.

Activity preparation:

The Monkey King's photo; In kind: 1 white flower, 7 pink flowers; A tree (two yellow apples and six red apples on the apple tree); 4 motorcycle headdresses; Every child has a train ticket with addition and subtraction formula, 1.2.6.7.8 digital card, "+"card, "-"card and "=" card.

Activity flow:

First, small game, review the composition of 8: We have learned the composition of 8, now let's play a small game, shall we?

Child: OK.

Teacher: Raise your little hand, and I'll give "1". (pointing to one), how much do you want?

Child: You give "1" and I give "7". (The gesture of five): 1 and 7 add up to 8.

Second, create scenarios to explore new knowledge 1. The appearance of the Monkey King aroused children's interest.

Teacher: Do all children in The Journey to the West like to watch it? Then who do you like best?

Child: the Monkey King and Pig Teacher: Look, who's here? (Showing pictures of the Monkey King) Child: the Monkey King.

Teacher: Today, the Monkey King will compete with our children to see who has the greatest skill.

2. the Monkey King juggles: We know that the Monkey King will change seventy-two. Look, the Monkey King pulled out a hair, said change, and a bunch of flowers (one white flower and seven pink flowers) came out. Please have a look. How many white flowers are there in the teacher's hand? How many pink flowers? How many flowers are there? How did you work it out? Please say the formula.

The children answered, and the teacher posted the formula on the blackboard. We know that addition has a commutative law, and the positions of the two addends before and after the plus sign are reversed, and the sum is unchanged. (The teacher exchanges the position of 1 flower and 7 flowers with gestures) Ask a child to say the formula and then paste it.

Teacher: Now send 8 flowers to xxx's children 1. How many flowers are there? Ask a child to say the formula and paste it: 8- 1=7.

Teacher: I sent seven flowers to xxx children this time. How many flowers are left? Ask a child to say the formula and post it: 8-7= 1.

Teacher: the Monkey King said that this boy is very good and can list so many different formulas. I'll pull out another hair to test the child. He conjured an apple tree (there are two yellow apples and six red apples on the apple tree). The teaching method is the same as that of the teacher: two were dropped later, and how many were left on the tree? Ask a child to say the formula and paste the formula 8-2=6.

Teacher: If six people drop, how many are left? Ask a child to say the formula and paste formula 8-6=2.

Teacher: the Monkey King said that I didn't hit the children after juggling twice. It seems that our children are really smart!

Third, the game "Driving a Train", consolidate the trainer: Who is calling? Oh, Wukong called and invited us to visit water curtain cave. Are you happy? Shall we go by train?

The teacher gave each child a train ticket, and the children worked out their own car numbers, got on the same car according to the numbers, and lined up behind the children wearing headdresses in an orderly manner. (You can't get on the train if you make a mistake), and you can also drive the train out of the classroom to the music of driving the train.

Teaching reflection

According to the age characteristics of young children, it is their nature to be active. At the beginning, their attention is very concentrated, their classroom discipline is very good, and their cooperation with teachers is very tacit. But after a long time, some children's attention may be distracted, and some children may be too excited because of the stimulation of games, so that the classroom order is a bit chaotic. At this time, teachers should give timely guidance, attract children with appropriate language, and adjust bilateral activities with children as the mainstay and teachers as the supplement, so as to make the classroom atmosphere active, orderly and lively, so that children can be in class.
