moving target
1, learn to sort objects within 3 from small to large or from large to small.
2. I am willing to express my sorting method in words and develop good operating habits.
3. Experience the fun of mathematical sorting activities.
Activities to be prepared
1, fun exercise-sorting
2. Teaching AIDS: an apple tree, two groups of three pictures of apples of different sizes, and two operation cards with small red flags.
3. One set of operation data for each child; One set of strawberries, bananas, oranges, watermelons, pineapples, pears and pomegranates are placed in 7 boxes respectively.
Activity process
First, introduce activities to stimulate children's interest.
1. Show the apple tree and guide the children to observe.
Teacher: Look, the apples on the apple trees in the orchard are ripe. Which child wants to pick apples?
2. Ask two children to choose apples together and guide them to compare the sizes of apples.
Question: What's the difference between these two apples? Which is smaller? Which is bigger? (small, big)
3. The teacher chooses another one to guide the children to compare what they say.
Teacher: The teacher will also pick an apple. See how this apple I picked compares with them.
(of)
4. Teachers and children are the same * * * Summary: Three apples are different in size. One is small, one is big, and the other is.
Second, learn to sort the three apples from small to large.
1. Sort from small to large: small-big-big.
Teacher: These apples want to learn the game of children queuing to drive the train. They want to ask you for help. Would you?
Please stand with the smallest apple as the head. Other apples follow the little red flag in order from small to large.
The direction is behind this apple. Who should be number one?
(Please 1-2 children come up)
Children and teachers talk about the rules of classification: small-big-.
3. Let the children practice sorting apples according to the teacher's requirements from small to large, and say while sorting:
Small.-large.
Third, children explore the order from big to small to sort apples.
1. Continue to show three apples of different sizes to guide children to observe.
Teacher: Look, how many apples have been picked here? Are they different too? (big, small, smallest)
2. The teacher introduced the sorting requirements: This time, these three apples are of different sizes, and I want the children to arrange in a row according to the order from big to small.
Please continue to try to operate the card and line up!
3. Children's operation activities, exploring the sorting method from big to small, the teacher instructed children to line up and said: big-small-minimum.
4. Please 1-2 children come up and show their sorting methods.
Fourth, teachers and children * * * together to sum up:
Today, the children are really great. They learned to classify three apples from small to large or from large to small.
Will also say: small-big-while queuing; Big-small-smallest.
Five, the game: send fruit.
1. Introduce the rules of the game for delivering fruits:
Teacher: Please ask the children to choose the fruit to send before sending it, and then join two good friends who take the same fruit.
Compare the sizes of the three kinds of water, and finally line up in the order from small to large or from large to small.
Take a small train to our class, will you?
2. Children are free to look for fruits, compare and negotiate with each other and queue up to deliver fruits in a certain order, and the activity is over.
