The activity target of 1 in the large class teaching plan is counted by groups.
1, learning 1-20 counts by group, two numbers;
2. Establish the concept of number groups.
Activities to be prepared
A set of teacher demonstration boards and a set of children's learning tools.
Activity process
First, the activity import:
Teachers and children play odd-even games, from 1 to 10, and then to 20.

Statistics of large class teaching plans according to the second group of activity objectives:
1, there are different ways to guide children to understand counting.
2. It can count groups in units of 2, 5 and 10.
3. Experience the fun of operation by counting.
4. Cultivate children's interest in calculation and the accuracy and agility of thinking through various sensory training.
5. Improve the interest in counting and the ability to think positively.
Activity preparation:
1, experience preparation: children have a perceptual experience of counting.
2. Preparation of teaching AIDS: light music, demonstration boards (20 pieces have been arranged), picture "group counting", round cards with different colors, and operation cards.
Highlights and difficulties of the activity:
1, the key: learn to count in groups.
2. Difficulties: Counting will be done in different ways.
Activity flow:
First, import the pictures.
1, show pictures to guide children to observe and understand how different groups in Unit 2 and Unit 5 count.
Teacher: How many balloons are there in the picture, children? How did you find out? Is there any other way to calculate?
3. Teacher: There are 10 balloons in the picture. Some children say there can be two twos. How do you count two twos? Let the children talk, otherwise how to calculate? How do you count to five?
4. Teacher's summary: 2 2 numbers are counted in groups of 2, and 5 5 numbers are counted in groups of 5.
Second, use the demonstration board to practice counting in groups of 2, 5 and 10.
1, the teacher shows the demo board: children, do you know how many pieces there are on the demo board? Think about what methods can be used to count?
2. Teacher: Ask a child to count at the front in his own way. Is there any other counting method different from his?
3. Teacher: If 10 has 10, how should I count it?
Teacher: Let the children take out their round cards, choose a color they like, listen to music and put them on their desks in turn. After the music stopped, the children stopped playing. (Children listening to songs)
5. Teacher: What color ring did you choose? How many? How do you calculate it? Are the total counts in groups of 2, 5 and 10 the same? What difficulties did you encounter in the process of counting? Which method is faster?
Third, the children's game "holding a group"
Teacher: Today, let's play a group game. The teacher will tell us the rules of the game:
All the children were pulled into a big circle. As they walked, they said, "Look, look, find friends, find some good friends?" The teacher replied, "I found two good friends." When the teacher says two, the children will hug each other, and then the teacher will find another child to count how many children there are. (There can be 2,5, 10) 2. Teacher's summary: Today we learned to count by an array, and we can try to count objects by 2, 5, 10 in our life.
Fourth, the activity is over.
Attached:
How to queue up to count the number of children: Divide children into two teams according to sex, and assign a child to count the number of children in each team. Count in units of two and say the total. Then specify the number of children with 5 and 10 respectively, and tell the total.
(In life, children can have two chopsticks and two numbers; Five five-digit meals; 10 digital instruments, etc. )
Activity reflection:
In the activity, children don't understand the concept of "two numbers" thoroughly, and some children can't count independently. Teachers should design several game links to train children to master the skills of "two numbers".
According to the third group of activities, the number of large classes is counted:
1, can master two twos and five fives within 50.
2. Develop the ability of grouping counting and the concept of array.
3. Be willing to participate in mathematical activities and experience the fun of different counting methods.
Activity preparation:
Orifice plate learning tool, white paper, pigment, clear water, towel.
Activity flow:
First, help the bear count balloons.
1, Bear's birthday, his father gave him a lot of balloons, and I can't count them. Please help! (The teacher shows the chess pieces)
2. Please calculate 1 child. "How do you calculate?"
3. Are there different methods? (Guide the children to find two numbers of 2)
4. The teacher demonstrated that two pieces of the same color were taken out in turn and placed in the first row. "How many are these?" (2).
5. Then put two, "How many now?" (4) in turn.
6. How many balloons did we count each time just now? (2)
