Teaching Plan of "Chicken Move" in Big Class Mathematics 1 1. Activity Objectives:
1, review the composition of 8, understand the meaning of addition and subtraction of the first and second groups of 8, and calculate the number according to the formula.
2, interested in addition and subtraction, experience happiness in the game situation.
3, writing and expression, hands-on operation, and actively participate in mathematical addition and subtraction activities.
Second, the activity preparation:
Material preparation: the composition of 7 is printed on the balloon; Background chicken's home, 8 addition and subtraction (activities, writing and playing), marker, rag, doll, clip, number 1-8.
Experience preparation: I have studied the composition of 8 and have a certain understanding of addition and subtraction within 7.
Third, the activity process:
(1) Review the composition of 8 (scene-celebrating the movement of chickens)
Game: Fly the balloon (Song Jingguess: There is something wrong with the balloon, let's fly the balloon, 8 can be divided into 1 and several, 1 and several to form 8 ...)
(2) Group study 8 The first group of addition and subtraction (the color of the chickens in the new house is different, and the chickens go to play)
1, according to different colors, children understand that 1 red chicken and 7 yellow chicken add up to 8, and the guiding formula is 1+7=8.
2. Chickens' positions are interchanged, and children feel that the total number of chicks remains unchanged (consolidating their understanding of additive commutative law). The guiding formula is 7+ 1=8.
3. Play with 1 chick and 7 chicks respectively to guide children to form 8- 1 = 7 and 8-7 = 1 to understand the meaning of subtraction.
4. * * * Take it with you.
(3) Inquiry learning 8 The second group of addition and subtraction (scene: looking at flowers, dressing dolls in front of the chicken house: braiding with clips)
1, dress up for the doll; According to the above formula, please use the clip to help you work out the numbers, not only compiling but also working out the numbers. Please have a try.
2. Send the doll to the corresponding garden. (For example, 2+6= sent to Garden No.8)
3. sort out the child's experience. Trigger: How many pigtails did you put on the doll? Why?
2+6=8, 6+2=8, 8-2 = 6, 8-6 = 2.
4. Summary: addition and subtraction of the second group of 8.
(4) Summary activities
1, see if the doll is crying. (evaluate right or wrong)
Expanding activities: practice addition and subtraction in regional activities and learn to be a doctor.
Teaching plan of "chicken movement" in large class mathematics II. Activity goal: feedback.
1, review the composition of 8, understand the meaning of addition and subtraction of the first and second groups of 8, and calculate the number according to the formula.
2, interested in addition and subtraction, experience happiness in the game situation.
3, writing and expression, hands-on operation, and actively participate in mathematical addition and subtraction activities.
4, like math activities, willing to participate in various arithmetic games, and cultivate rebellious thinking.
5. Understand the application of numbers in daily life, and preliminarily understand the relationship between numbers and people's lives.
Second, the activity preparation:
Material preparation: the composition of 7 is printed on the balloon; Background Chicken's home, one or two groups of 8' s addition and subtraction (moving, writing and playing'), marker, rag, doll, clip, number 1-8 Experience preparation: I have learned the composition of 8 and have a certain understanding of addition and subtraction within 7.
Third, the activity process:
(1) Review Composition 8 (Situation-Celebrate the Movement of Chickens) Game: Fly balloons (Song Q&A: There is something wrong with balloons, let's fly balloons. 8 can be divided into 1 and several groups, 1 and several groups of 8 ...
(2) Group study 8 The first group of addition and subtraction (the color of the chickens in the new house is different, and the chickens go to play)
1, according to different colors, children understand that 1 red chicken and 7 yellow chicken add up to 8, and the guiding formula is 1+7=8.

(3) Inquiry learning 8 The second group of addition and subtraction (scene: looking at flowers, dressing dolls in front of the chicken house: braiding with clips)
1, dress up for the doll; According to the above formula, please use the clip to help you work out the numbers, not only compiling but also working out the numbers. Please have a try.
2. Send the doll to the corresponding garden. (For example, 2+6= sent to Garden No.8)
3. sort out the child's experience. Trigger: How many pigtails did you put on the doll? Why?
The second group of addition and subtraction: 2+6=8, 6+2=8, 8-2=6, 8-6=24, and the sum is 8.
(4) Summary activities
1, see if the doll is crying. (evaluate right or wrong)
Expanding activities: practice addition and subtraction in regional activities and learn to be a doctor.
Activity reflection:
Give children enough opportunities to communicate with their peers and solve problems. Whenever children encounter difficulties, I will let them find their own way first and try boldly. Attach importance to regional activities. After the activity, pay attention to the guidance of the activity extension, and let the children operate freely in the regional activities and make records. In the whole activity, we try our best to embody the harmonious teacher-student relationship with children as the main body and teachers as the leading factor. Most children can take the initiative to learn, enjoy learning, and achieve the expected goals.
