Teaching plan for math activities in large classes: tadpoles looking for their mothers 1 1. Activity objectives:
1, to help children establish the corresponding relationship between the number of things in playing games, further understand the practical significance of 10, and consolidate the understanding of logarithm formation.
2. On the basis of being familiar with the story, guide children to use what they have learned to help tadpoles find their mothers, so as to gain a sense of success.
Second, the key points and difficulties:
1, to help children establish the corresponding relationship between the number of things in the activities of playing games, to further understand the practical significance of 10, and to consolidate the understanding of logarithm formation.
Third, the design ideas
Spring is beautiful, spring is the season when everything grows, and the surrounding environment is constantly changing. We want children to feel the changes of some animals and plants in spring. At the beginning of the theme, scientists collected some information about spring, such as tadpoles, frogs, butterflies, bees, silkworm babies, books, pictures and so on. Therefore, learning about spring needs to create a situation suitable for children's emotional attitude, existing experience and cognitive habits, rather than simply mechanically instilling objective and ready-made knowledge into children. With the deepening of the theme and the reality of the children in our class, the children in our class are very curious about the growth of tadpoles, and they can actively explore. According to the spirit of the second curriculum reform, children's learning is based on interest and life experience. So I designed this activity of "Little Tadpole Looking for Mother", which is mainly to let children further perceive and understand the concept of logarithm in the process of getting familiar with the story content and doing some fun things, and improve it on the original basis.
Fourth, material creation:
Many tadpoles wear breastpieces (tadpoles on the front, frogs on the back, and the number on the back is 1- 10), and a small animal (all kinds of animals with two legs, four legs and eight legs, but no frogs) is given to children.
Verb (abbreviation for verb) activity guide:
(a), scene import:
1, spring is coming, and the water in the river is getting warmer. A group of tadpoles are swimming in the pond. (Show tadpoles) Count, how many tadpoles are there? ( 10)
Tadpoles swim and swim in the pond. I am so happy. But one day they remembered their mother: "Where is our mother?" "Let's help the tadpole find his mother.
(2) The tadpole looks for his mother.
1, children play with tadpoles.
2. The tadpole swam and swam and met the mother duck quacking anxiously! It turns out that the mother duck's child can't be found, and she is very anxious. The tadpole said, let me help you find it! Mother Duck said, OK, OK! My children are all marked, please help me find them quickly. Children play with tadpoles to help mother duck find ducklings. Let the duckling go back to his mother, and the teacher and students will verify whether it is correct. ) When the tadpole saw how happy the duckling was around his mother, he really envied it. He remembered his mother and asked, "Do you know our mother? Do you know what kind of person he is? " Mother Duck smiled and said, "Your mother has four legs, probably just in front. Go find them! " "
3. Tadpoles continue to swim forward. Hey, what did they see? There are many animal friends together, and the little tadpole thinks, "Is our mother here?" Ask the students to find a friend with four legs. There are so many. The tadpole said, "Which one of you is our mother?" Everyone laughed. "We are not your mother. Your mother has two big eyes, a white belly and a green dress. "
The tadpole swam forward again and saw a guy with big eyes, big mouth, four legs and green clothes squatting on the lotus leaf in front of him. Is this our mother? Do you think so? Mother frog saw it and said, "Baby, I'm your mother. You've become a frog." (The baby turns over his breastplate to reveal the frog) "No, you have children, some don't, and some mothers are catching pests. Look, here they come. Show it to your mother frog (there is a small card on her belly). Children, swim to your mother.
(Children ask their mothers to verify each other)
(3) (activity extension) Little frogs catch pests
The little frog followed his mother frog to the shore and went into the field to catch pests and protect crops every day.
The teacher led the children to the outdoor field to simulate frogs catching pests.
Teaching plan for large class mathematics activities: tadpoles looking for their mothers 2 teaching objectives;
1, through situational games, guide children to learn to see points and formulas according to different characteristics of objects.
2. Train children's thinking flexibility.
3. Cultivate children's comparative judgment ability.
4. Guide children to actively interact with materials and experience the fun of mathematics activities.
5. Stimulate children's interest in learning.
Teaching preparation:
There are several addition and subtraction cards of 5, a background picture, an animated picture of ducks, fish, turtles, white geese and frogs, and six tadpoles (different sizes and colors).
Teaching process:
1, review the composition of 5 (show the background picture) Introduce a story of a tadpole looking for its mother, let the children observe how many tadpoles there are and what are their different characteristics, and list the switching formula of 5.
five
1 4
2 3
3 2
4 1
2. Help tadpoles find their mother
When you meet ducks, fish, turtles, white geese and frogs, ask them to list formulas within 5 according to their own characteristics (size and bow). Only when the answer is correct can they be told where to find their mother.
Duck 1+4=5 4+ 1=5.
Fish 5- 1=4 5-4= 1
Tortoise 2+3=5 3+2=5
Great White Goose 5-2=3 5-3=2
3. "Driving the train" game
Tell the story "The tadpole found her mother and grew up, becoming a frog. They got on the small train with their mother and went to the farmland to catch pests and protect crops. " Children play the role of tadpoles, hold a train ticket (formula is less than 5), calculate the numbers, sit in the corresponding number of "carriages" and arrange four "trains".
Teaching reflection:
The Little Tadpole Looking for Mom is a traditional fairy tale, which is deeply loved by children because of its vivid and interesting content. This course runs through children's familiar stories, sets game scenes with stories, asks questions step by step with the help of the dialogues of characters in stories, and makes children actively participate in the course. The classroom atmosphere is active and the teaching effect is good.
