The goal of 1 activity in the "high-volume" math teaching plan for large classes;
1, explore the tools and methods of measurement, and record the measurement results in units of natural objects.
2. Be able to cooperate with peers to solve problems.
3. Cultivate children's comparative judgment ability.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Experience the life of mathematics and the fun of mathematics games.
Activity preparation:
1, rich experience in measuring the side length of graphics.
2. Cartons, mats, wooden sticks, long wooden blocks, ropes, etc. , children's record sheet and pen.
Highlights and difficulties of the activity:
Master the basic methods of natural length measurement; Cultivate children's interest in math activities.
Activity flow:
First, ask questions to stimulate children's interest in participating in activities.
1, Teacher: When the children in the middle class are playing hospital games, they encounter a difficulty. They want to measure their height like doctors, but they can't use a ruler and can't find other materials to measure their height. Can you help them think about what materials can be used to measure their height?
2. Teachers guide children to discuss natural objects that can be used for measurement. Every time a child talks about a material, the teacher asks the child how to use it. Such as: "How to measure the height of the box? what are you going to do？ Just pick up the box and you can know the height of the child? " "How to measure the height of building blocks? What do you think will happen if the building blocks stand upright? How can I not let go and still be born high? "
Second, teachers provide materials to guide children to explore measurement methods in groups.
1, Teacher: Which material do you think is suitable, just try it. What if there are few materials but many people want to use them? The teacher instructed the children to learn to work together and use the same materials. )
2, children's operation, teachers observe children's measurement.
Third, discuss and solve the difficulties encountered in the measurement, and further clarify the measurement method.
1, the teacher encouraged the children to talk about the difficulties encountered in the operation.
2. Children communicate with each other to solve problems.
3. The teacher shows a set of methods for children's measurement to guide children to observe the existing problems.
4. Teachers guide children to further clarify the specific methods of measuring height.
Fourth, children explore again and record the measurement results.
1, Teacher: Let's measure it later and think about how to measure the height accurately. After measuring your height this time, you should not only record what materials you used and how you measured them, but also record how tall you are with numbers and marks.
2, children's operation, the teacher's individual guidance.
Show the process and results of children's recording and communication measurement.
1, guide children to find out what materials their peers use from the records. ...
2. Let the children introduce their own measurement methods to each other.
3. Teachers put forward the problems that children encounter in measurement or recording, so that children can think after the activity.
Activity expansion:
1, aiming at children's problems in activities, take them to explore further.
2. Learn more about measuring tools.
"Cutting Height" large class mathematics teaching plan 2 large class teaching plan "Cutting Height" is suitable for large class mathematics teaching activities, which enables children to initially develop their ability of observation, comparison and reaction, understand the concept, conditions and methods of measurement, form a comparative concept, and cultivate children's habit of speaking in operation.
[activity]
Understand the concept, conditions and methods of measurement and form a comparative concept. Preliminary observation, comparison and reaction ability. Cultivate children's habit of speaking when operating.
[Activity preparation]
Plastic rope, cardboard, paper rope, tape measure, etc.
active program
1, information: The children are all in the big class. Everyone has grown up by one year. I also found that children are getting taller and taller this year.
2. Setting questions: But do you know which child is the tallest? Some children say he is the tallest, while others say he is the tallest. How do you know for sure that it is the highest?
3. Children guess the tape: Let the children guess which child plays the game the most, put the child who guesses the highest after his name and fill in the tools he chooses.
4. Verification: Let each child find a good friend to measure and attach the measurement results to the recording paper for comparison.
5. Activity extension: It is inaccurate to visually compare the length of things, and we must know it accurately through comparison. The same is true in real life.
6. Raise a new question: We now know who is the tallest through children's intelligence. Guess his legs are also the longest?
End of activity
Children explore together.
Activity reflection:
1, the children made activities by thinking, watching and finishing, which deepened their understanding of the object quantity and the measuring tools of different quantities. Although the participation is high, it is more difficult for the children in our kindergarten, especially in the recording activities. ! Self-defeating The teacher taught the plan. ! Because I didn't give careful guidance in this aspect in my usual teaching activities and neglected the cultivation of this ability, it is difficult for children to record it.
2. Give children enough opportunities to communicate with their peers and solve problems. Allow them to make mistakes and try other methods. Whenever children encounter difficulties, I will let them find their own way first and try boldly.
