Design background This is a routine mathematical activity. In order to make children more interested in learning and better achieve teaching goals, I combine factors such as seasons, songs and games to let children feel the characteristics of seasons and master learning content in happy games. Activity target 1. Consolidate identification, count within 5 minutes, and take things. 2. Play the game according to the mathematical rules and experience the fun of the game. Key points and difficulties Key points: Consolidate the identification and counting of numbers within 5, and the difficulty of taking things according to numbers: Prepare a picture of the garden where games are played according to mathematical rules, and the animals and plants in the garden should have a corresponding number of digital cards. Each person has 4-5 clips, and each person has a circular homework paper with 1 to 5 written on it. Activity flow (1) Enter the activity room Teacher: What season is it, children? (Spring) So what are the characteristics of spring? (Flowers are blooming, grass is sprouting, and the weather is getting warmer ...) Oh, look, the little butterfly is here, too. (Show the butterfly finger and stick it on your hand. ) Little Butterfly said that she would take the babies from Class 4 to see the Spring Garden. Do you want to go? Then you can sing Fluttershy's song and take it to see! (Children sing songs and butterflies, and follow the teacher into the activity room) (2) Observe the pictures to show the pictures of the garden, and ask the children to observe. What do you see? Children observe and say the animals and plants they see and the number. After the children have finished speaking, show the digital cards one by one. How beautiful the flowers in the garden are. They also want to play games with you. Do you welcome them? The teacher gives each child a piece of homework paper and five clips. 3. Teacher: Now, please ask the children to help the flower heart open the beautiful petals. If the flower heart says 3, it means three petals. Please insert three petals for it. If the flower heart says 4, it means 4 petals, then 4 petals should be inserted. 4. Children operate handmade paper or clips. 5. Let the children communicate with their peers, tell them the number of their petals, and ask them to help check whether they are right or not. (4) Game: The teacher reads a nursery rhyme, and the children clap their hands with the teacher in the activity room. After reading nursery rhymes, they "bloom" according to the teacher's requirements. If the teacher says that three flowers will bloom, the three children will hug each other. (5) Play by train. According to the teacher's request, the children took the train with the corresponding number of carriages. (6) End of the activity: Children, let's get on the bus and see what beautiful scenery there is in spring. Take the children to sing and leave the activity room. Teaching reflection From the activities, we can see that children have a good grasp of the teaching content, which is reflected in the operation. The children also had a good time in the game. In future courses, it should be organized in the form of games to satisfy children's interests. But in the activity, the teacher talked too much, so the future teaching should be liberalized, giving children more space to explore for themselves.
