moving target
1, children feel the decomposition of 6 through independent exploration and hands-on operation, and master the five points of 6.
2. On the basis of the decomposition and composition of perceived numbers, master the laws of number increase and decrease and mutual exchange.
3. Develop children's ability to observe, analyze and record, and cultivate children's interest in mathematics.
Teaching focus:
Perceive the relationship between the whole and the part, and learn and record the five points of 6.
Teaching difficulties:
Summarize the law of decomposition and synthesis of numbers within 6.
Activities to be prepared
Teaching AIDS: a large wall chart (there are two houses on the map, and there is a decomposition of 6 spaces on both sides of the map), 6 panda cards, markers and recording paper.
Learning tools: each child has a picture (there are two houses on the picture, and there is a space on each side of the picture with a score of 6), 6 animal cards, pencils, erasers, and 1-5 digital cards.
Activity process
(a), the beginning part
1, import:
Teacher: Autumn is coming. Mother Dashu is busy writing letters, writing here and there, and all the red leaves and yellow leaves are finished.
Q: Who has received the letter from Mother Tree? Guide children to answer which small animals have received the letter from mother tree.
Q: What did Mother Tree write in her letter? Tell the animals to prepare for the winter.
Teacher: The little animals received the letter from Mother Tree and built many new houses. They are going to spend the winter in the new houses.
2. Show the big wall chart, which leads to "the decomposition of 6"
Teacher: The panda family has been allocated two houses. There are several pandas in the panda family (including six with children) to display the digital card of "6".
Teacher: How to divide six pandas into two houses? The panda is worried. I don't know how to divide it. There are several kinds of distribution. Please tell the children.
(2) Basic part
1, please help your little animals to divide the house.
(1), children observe their learning tools, talk about what small animals they are and count the number of small animals (6).
(2) Children divide six small animals into two rooms and record the results of each division.
2. Let the children talk about the results of their own points. The teacher recorded the children's division of labor on the record paper.
3. The teacher summed up the children's points and summed up the five points of "6".
4. Observe children's disorderly division and guide learning to decompose "6" in an orderly way.
(1), the teacher demonstrated that six pandas were divided into houses, and counted the number of small animals in the two houses with the children, and recorded the results. "6" can be divided into 1 and 5,2 and 4,3 and 3,4 and 2,5 and 1.
(2) Children observe the decomposition formula of "6", initially grasp the orderly decomposition composition of "6", and understand the law of number increase, decrease and exchange.
5. The child divided the house for the small animals for the second time, tried to break down the "6" in an orderly way, and recorded the results of each division.
(3), the end part
The game "find friends"
Each child chooses a digital card (1-5) to wear, and together with the music of finding friends, find the child with the number "6".
