The goal of kindergarten mathematics teaching plan "natural investigation" 1 activity;
1. Encourage children to choose their own measuring tools to measure the surrounding objects, and find the relationship between measuring tools and measurement results through exploration and comparison.
2. Understand the application of measurement in life and stimulate children's interest in measurement.
3. Willing to cooperate and communicate with peers to solve problems.
4. Let the children judge the quantity correctly.
5. Experience the life of mathematics and the fun of mathematics games.
Activity preparation:
1, the child has preliminary measurement experience.
2. Rulers, ropes, soft rulers, straws, sticks, short building blocks, pencils, chopsticks, paper clips, boxes, books and other items.
3. Record sheet, watercolor pen and magnetic board.
Activity flow:
I. Introduction: Presentation of the mandate
Today, children come to be "little surveyors". They use three different tools to measure the same edge and record the measurement results.
Second, exploration: grouping measurement and recording.
1. Children can freely negotiate and choose the right measuring tool to measure the same edge of an object.
2. The teacher visits and observes, listens and understands the situation of children's measurement.
3. Encourage children to measure with different tools and record the measurement results.
Third, sharing: the process and results of dissemination measurement
1. Stick the measurement records of each group of children on the magnetic board, and the children will communicate while watching and discuss the measurement process and results.
2. Guide children to analyze and record the results and talk about why there are different results. And in the analysis and comparison, we get different experiences of measuring the same edge with different measuring tools.
Game: question and answer game to inspire children to measure again.
1. What tool is used to measure the long side of the blackboard at least (or at most)? Why? Have a try.
2. There are three tools with different lengths to measure the length of the activity room. Which tool measures the fastest? Why? Have a try.
Without these tools, how can we measure the length of the activity room? Have a try.
The expansion of verb (verb's abbreviation);
Encourage children to try again to explore the use of various tools to measure the height and distance of objects.
Activity reflection:
Because the selected teaching content-natural investigation is a mathematical activity that children are interested in, and it is also a highly operational activity; Moreover, I have prepared enough materials for young children, and I can make it available to everyone. Therefore, the children are very active and enthusiastic in the activities, and everyone is very involved in the exploration activities. Many children who usually don't like hands-on are also active in this activity. Children have been able to master more accurate measurement methods through many free exploration activities; In the measurement, children's ability has also been developed, especially their hands-on ability and exploration ability.
The first link
Appropriate behavior: In the first step, let children make exploratory measurement and discussion according to their own measurement experience, let children speak their own practices and ideas, and play a role in learning from each other. The demonstration of individual children and teachers gives children a preliminary understanding of the correct measurement methods.
Disadvantages:
1, there are many children, but the space is limited. Choosing the height of the chair to measure will block the children's sight and bring inconvenience to their activities.
2. When I demonstrated the correct measurement method, I chose the same measurement object as the children-the chair. Because the space is blocked, the children behind and next to me can't see clearly.
Question:
1, how to choose children's exploration objects and what guidance teachers should give are all very important, but I lack full consideration in this link.
2. Does the teacher have to choose the same measurement object as the child to demonstrate and explain? How to choose to better consider each child's vision?
Countermeasures:
1, children can choose the edge of the chair backrest as the measurement object, which will not only make the children's activity space not too narrow, but also facilitate their exploration.
2. It is worth thinking about: Can you draw a straight line on the blackboard and demonstrate it in a clear way?
The second link
Appropriate behavior: I fully consider the practical operation characteristics of the children in this class, and adopt the methods of "releasing and collecting" and "releasing and collecting again" to teach, so that the children can abide by the rules and study better; The organization of teachers is also relatively easy.
Disadvantages: many small links are designed, and a lot of materials are put in. Children want to try everything, and the operation time is not enough.
Question:
1. Each small link is designed for one goal-continue to learn a variety of natural measurement methods, and find that different measuring objects are suitable for different measuring instruments during the activity. So, can you combine the first small link with the second small link to give children more time to operate?
2. Will it be too difficult? Because it is not easy for children to master the correct measurement method, what's more, after they initially feel the measurement method, they will immediately step into the second goal-trying to let children find out for themselves that different measuring objects are suitable for different measuring instruments. The choice of measuring tools is related to the measuring object. Will the process be too fast?
Countermeasures:
1. Consider dividing this teaching content into three classes, focusing on "learning a variety of natural investigation methods". The second link is to let children learn and consolidate the correct measurement methods through free exploration and operation. Of course, we can consciously guide children to measure objects with round edges in activities and learn different measurement methods.
2. Put the goal of "trying to let children find different measuring objects suitable for different measuring instruments, and the choice of measuring tools is related to the measuring objects" in the second class. In this way, children will not study so hard, the operation time will be easier, and they can break through difficulties more effectively.
Overall feeling: When designing an activity link, we should not only design the link according to the characteristics of children's activities, but also fully consider the purpose and feasibility of each link and the handling of every small detail. Their professional level is also very important, and the setting of questions, random observation and the grasp of guiding words all need further training.
Encyclopedia: measurement is to describe observed phenomena with data according to certain laws, that is, to describe things quantitatively. Measurement is the quantization process of non-quantized objects.
Natural investigation, a math teaching plan for large classes in kindergarten;
1, like to participate in surveying activities, willing to use the knowledge of natural surveying to solve the problems encountered.
2. Choose tools independently, measure the length of objects, get a preliminary understanding of the relationship between measuring tools and measurement results, and learn the correct measurement methods.
3. Stimulate children's spirit of inquiry, and develop children's abilities of observation, comparison and judgment in hands-on activities.
Activity preparation:
1, measuring tools and chalk of different lengths
