The background of the activity design of large class 1 math teaching plan in kindergarten.
Addition and subtraction within 5 is the basis of addition and subtraction within 10. It is difficult for students to learn from kindergarten, and it is difficult for most students to master it well. Therefore, I focus on the connection between the calculation of perceptual number and life, and experience the significance of addition and subtraction in specific situations and activities.
moving target
1, let children understand the meaning of addition and subtraction.
2. Let the children master the addition and subtraction of 5.
3. Let children learn to answer simple application questions of oral calculation addition and subtraction, and initially cultivate their ability to analyze problems.
4. Sing along with the melody of the song.
5, can sing accurate tunes, articulate, and can sing boldly in front of the group.
Teaching emphases and difficulties
Make children learn to answer simple addition and subtraction oral calculation questions and cultivate the ability of preliminary analysis.
Activity process
1, talk about it and arouse children's interest.
2. Review the composition of 5.
3. Display visual teaching AIDS
4. Guide children to dictate the addition and subtraction application problems of 5.
5. Play the game "Who is the fastest"
Step 6 write the formula
7. The teacher makes a summary
Teaching reflection
1, contact students' real life, and let students realize that addition and subtraction are around us.
Students' real life makes them realize that addition and subtraction are around us.
3. In order to make students do oral calculation correctly and quickly, they must also be trained through various forms of exercises. I actively advocate the diversification of algorithms and provide students with opportunities for mathematical communication, with the aim of promoting students' mathematical thinking activities and improving their mathematical thinking ability. Because of the diversity of algorithms, different students have different problem-solving strategies. They will use their own methods to solve problems and have a deep understanding of solving mathematical problems, thus gaining experience in learning mathematics. These algorithms are the results of students' thinking according to their own basic knowledge and life experience. Each different algorithm represents a sense of innovation, thus effectively training divergent thinking.
The Design Intention of Subtraction within 2/5 of Mathematics Teaching Plan for Kindergarten Large Class
This semester, the children in the big class have begun to learn the division and addition and subtraction of numbers within 10. In view of the situation that children's thinking in images is dominant and logical thinking is almost absent, I have integrated mathematics learning into stories, PPT animations, games and other activities, and achieved good results. Children learn easily in this learning atmosphere, and their teaching goals are achieved unconsciously. My design idea is as follows, and I hope to get criticism and correction from my peers.
moving target
1. Learn the subtraction of 5, understand the quantitative relationship between the graphs, and understand the meaning of "going" and "staying".
2. Learn to express the meaning of subtraction formula in concise language.
3. Experience the fun of math activities.
Activities to be prepared
1.PPT, every child has a set of digital operation cards.
2. There is a mailbox with the number 1 ~ 4, which contains several "letters" with an addition formula within 5.
Everyone will get a set of cards and pens.
Activity process
Play the game of "touch the ball" first and review the composition of 5.
Teacher: Children, today the teacher will play a game of "touching the ball" with you.
Explain the rules of the game: the number of balls the child said and the number of balls the teacher said add up to five. For example, the teacher said, "How many balls does my ball touch?" The child replied, "Your 1 ball touched 4 balls". Children can answer in groups or practice alone.
Second, introduce the topic and learn the subtraction of 5.
1. Show PPT①.
Teacher: I played the game of "touching the ball". I want to take you to the park. Let's go!
(1) How many buses are there at the station? What is the number of babies? How many cars did you drive? What is the number of babies? How many cars are left?
(2) Teacher (showing "-"): What does this symbol mean? (Guide children to discover the meaning of "minus sign". )
(3) The teacher answers the blackboard according to the children: 5- 1 = 4 (Read this formula together. )
(4) Teacher: What does this formula mean? (Can guide children to understand the meaning of the formula. )
(5) Teacher: Please tell the meaning of the formula with the teacher's picture and put a pendulum formula.
2. Show PPT②: How many butterflies are there in the garden? What is the number of babies? How many butterflies flew away? (2) What is the number of babies? How many butterflies are left?
3. Show PPT③: There are 5 fish in the pond, 3 fish have swam away, how many are left? Please use the formula.
4. Show PPT④: Is there any bread in the grocery store? How many pieces did you buy? How many pieces are left? Please use the formula.
Third, the game: sending letters (see the calculation)
(1) Show the game materials 1-4 e-mail box and many letters for children to observe, think and discuss the rules of the game.
(2) Let the children open four mailboxes in groups and check whether the "letter" is delivered correctly according to the rules of the game.
Fourth, look at the graphic calculation and further master the subtraction within 5.
Teacher: Children, today the teacher took you around the park, saw beautiful scenery, tasted delicious food, learned subtraction calculation, and played the game of sending letters. Now I want to test you. Look at these pictures, work out the formula, work out the answer and see who is the best.
Children's operation, teachers' tour guidance.
Teacher: How did you arrange it? What does this formula mean? (According to the children's answers on the blackboard, verify collectively. )
Five, the application of contact life
1. Teacher: Have you ever thought about what can be calculated by subtraction in life?
2. When you get home, will you ask your parents some math questions with the skills we learned today?
