Activity content: Who is older and who is younger (relatively large) Activity class: Children's small class activity subject: Mathematics activity goal: 1. Children learn to compare the size of objects, which can be expressed by "big" or "small". 2, can simply classify the size of the object. 3. Interested in participating in math activities. Emphasis and difficulty of activities: children learn to compare the size of objects, which can be expressed by "big" or "small". Activity preparation: 1, toys of different sizes. 2. Big apple trees and big apple cards; Small apple tree, small apple card. One big card for Papa Bear and one big card for Bear. 3. A big basket and a small basket. Activity flow 1. Teachers create situations to stimulate interest. Children, are you happy that the bear family invited us to be guests today? Let's leave now. (Clapping hands into the classroom) Look, Bear and Dad are welcoming us. Then let's say hello to them! Baby, who is bigger than the bear and dad? (Papa bear is big, Baby bear is small) Please hold out your little hands, and I will hold out my big hand. Let's clap our hands with Baby Bear. Second, children operate activities and compare the sizes of various objects. 1, children, Baby Bear has prepared many toys of different sizes for children. Everyone plays with two toys of the same kind. Compare your two toys, which is bigger and which is smaller? Everything is the same under the guidance of the teacher. Children go to the operation area to play with toys, and the teacher guides the children appropriately. Children can compare the size with two balloons, or with two cars and two balls. ) 3. The teacher explained the comparison of sizes: The teacher showed two balls with different sizes, which was bigger and which was smaller. 4. Teacher's summary: If children want to know which thing is big and which thing is small, they have to put it together to know. Third, guide children to be the same size. 1, the children did a great job. Let's encourage ourselves (children clap their hands). Hey, children, please put your little hands together. What did you find? Guide children to say that their hands are the same size. 2. Besides our small hands, which parts of our bodies are equally big? Guide children to say that their feet, shoes, socks and eyes are the same size. Summary: Smart babies, you have found many things of different sizes, and you have also found things of the same size in us. You're amazing! Fourth, the classification game "picking apples". 1, Bear's orchard has a bumper harvest, and it asks us to help pick the fruit. Baby, what is this? (Two apple trees) Are they the same size? Which tree is bigger? Which tree is smaller? 2. What kind of apples did these two apple trees bear? The apples on the big apple tree are big, and the apples on the small apple tree are small.

The children began to play the apple picking game, and the teacher paid attention to guiding the children to classify according to size. Summary: The children did a good job. The bear family thanked us very much and gave us the apple. What should we say to them? (thank you). End of the activity: Did the babies have fun at Bear's house? Let's say goodbye to Baby Bear. The teacher led the children out of the activity room while doing the action. Activity reflection: The above is a small class math activity I designed. In order to get a good teaching effect, I spent several days preparing enough teaching AIDS. But in the actual teaching work, I didn't finish it better, because the teaching AIDS I usually design are not as novel and colorful as this, and the children are used to it. Today, my teaching AIDS excited every child, especially when I walked into the activity room and saw Father Bear and Baby Bear, the children's eyes were attracted. When I want to play clapping games with my children, the children's eyes are still looking at the bear and his son. In the stage of classified games, children's interest is very high. Before I said anything, the children began to choose them. It seems that I haven't done my formative education yet. The children in Yang Kun pushed the children around them to put the apples into the basket quickly. Most children can distinguish size, but when describing it in words, Wang's voice is so small that he can't speak clearly. Other children's language is very clear, which can explain which is bigger and which is smaller. In short, the teaching objectives of this activity class have been basically completed. What impressed me most after this class is that children in small classes like vivid and colorful teaching AIDS best. In future activities, we should make more efforts to make teaching AIDS that children are interested in, not only for simplicity, but also for children to learn a lot from activities.
