Quality mathematics course for kindergarten middle class

Activity objectives

1. Review the counting method of pomegranate receptacles arranged in a closed shape.

2. Try to use statistical methods to record classification results, and be willing to introduce your own operation results in concise language.

Activity preparation

Already have preliminary contact with closed counting: one set of classification boxes, statistical tables, and pens for each person; one set of pomegranate receptacles picked up by children. "Pomegranate grows up quickly" operation picture: pomegranate receptacle - small pomegranate - blue pomegranate - mature pomegranate.

Activity process

1. Review the counting method of objects arranged in a closed shape.

(1) Count how many petals there are in the pomegranate receptacle

Teacher: Ask the children to each take a pomegranate receptacle from the plate and carefully count how many petals it has? Are you What method is used to count?

Summary: When counting petals, you must first identify a starting place. You can mark it, and then continue counting petals one by one, so that you know where to count. Finish. No more missing numbers or double counting.

(2) Check each other and re-determine the number of petals on the pomegranate receptacle.

Summary: The number of petals in pomegranate receptacles is different.

2. Classify according to the number of receptacle petals.

(1) Use the classic dialogue from the story "Three Butterflies" to explain the operation requirements, such as "House No. 4 said, 'Pomegranate receptacles with 4 petals, please come in. Don't come in with other numbers."'5 House No. said, 'Please come in with pomegranate receptacles with 5 petals, but don't bring in other numbers.'

Sorting boxes:

(2) Children operate according to the number of receptacles. , send 5 pomegranate flower receptacles to the corresponding digital classification boxes.

(3) Children show each other, introduce their classification results, and talk about how many pomegranate receptacles were invited to rooms 4, 5, 6, and 7 respectively.

3. Try to use statistical methods to record the classification results.

(1) Teachers discuss with children and establish recording methods.

Show the statistical table: Ask the children to carefully observe what they see on the recording paper? Guess what they mean?

(2) Children operate and record the classification boxes with pip symbols. The number of pomegranate receptacles with different number of petals.

Teacher tour guidance: pay attention to the methods and steps recorded by each child, and understand the children's problem-solving strategies.

(3) Guide the children who finish first to look at their recording paper and find the pomegranate receptacle with the most petals and the pomegranate receptacle with the least petals.

4. The game "Pomegranate is growing up fast".

(1) Teachers and children establish the rules of the game: use concise words to tell the number of pomegranate receptacles with different numbers of petals. After the description is correct, the pomegranate receptacle will slowly grow up. (Children use complete language to express the number of pomegranate receptacles recorded by themselves, such as: a pomegranate receptacle with 5 petals has 1 flower in a ***, a pomegranate receptacle with 6 petals has 3 flowers in a ***... Children's narration After it is correct, use the pulling teaching aid to demonstrate the process of the pomegranate growing up)

(2) Communicate with each other and learn to express the results of your operations in the correct language.

(3) Play the game "Pomegranate is growing up quickly". The children will tell the story in turn and use pulling methods to show the process of the pomegranate receptacle slowly growing.

Reflection on activities

Educational content comes from life. After I discovered the interest of young children in pomegranate receptacles, I continued to explore and discover the educational value hidden in the children's interest: the number of petals in the pomegranate receptacles scattered on the ground is different. From this, I creatively designed an educational activity to classify and count pomegranate receptacles, turning a common content in life into meaningful teaching materials. As problems continue to be solved, children's original interests continue to deepen and develop, which in turn triggers new activities and solves some common practical problems in life through statistical methods. For example, make purposeful classification statistics for toys, family members, and even some common things in life.

Pay attention to the guidance of the activity process. In order to avoid children's laissez-faire and purposeless operation behavior during the activity, I clearly explain the purpose, requirements, and specific operation methods before the operation, and then let the children operate freely. For example, the classic dialogue of the story "Three Butterflies" is used to effectively put forward operational requirements; when trying to use statistical methods to record classification results. I encourage children to independently discover the secrets of the recording paper and explore recording methods; when displaying and communicating the results of operations, I also use the game situation of the game "Pomegranate is growing up" to put forward narrative requirements, and consciously prompt the children to use complete language to complete the process. Expression. This better eliminates formalistic operating phenomena.

There are also shortcomings in this event, and some links need further adjustment and improvement. The main aspects are as follows:

1. At the beginning, guide the children to count the number of petals in the pomegranate receptacle. Because counting is in a closed state, children have many different methods. However, the teacher ended this link too hastily and concluded too early, and the teacher replaced the children's answers. This link should allow children to independently explore various effective counting methods, paving the way for the subsequent classification of pomegranate receptacles with knowledge and skills.

2. When guiding children to try to record the classification results, although the teacher guides the children to observe the record sheet independently. Discuss recording methods, but teachers lack good evaluation summaries, resulting in some children recording errors.

3. The atmosphere in the activity was harmonious and the interaction between teachers and children was good. However, the interaction between students and students was insufficient, and more emphasis was placed on children's individual exploration. Reflection after the activity, in the process of classifying pomegranate receptacles, children can be guided to work in groups, and some can perform classification operations. Some record statistics, and some conduct external exchanges and displays, etc. This can better cultivate children's cooperation ability and the ability to proactively discover and solve problems.

4. Teachers’ evaluations lack motivation and pertinence. When faced with children’s answers, they only use “you are so smart” and “you are awesome”. You can also say "Who has a different method?" "The child said in complete words that there are 2 pomegranate receptacles with 5 petals" etc. It enables children to feel that teachers attach great importance to each of their views and opinions during the exploration process. It also helps children to answer questions better and refine the value of exploration.
