Math teaching plan for middle class: Understand ordinal number 10/target.
Let children know the difference between cardinal number and ordinal number, and learn to distinguish ordinal numbers within 10.
prepare
1, 5 pasted apple pictures, each with 1 ~ 5 apples, each with different colors; 10 animal, 10 velvet step (the shape of which the side becomes higher step by step, which is convenient for sticking small animals), and velvet board.
2. Every two children have five pictures of bananas or other fruit bowls, the number is 1 ~ 5. Each set of digital cards is from 1 to 10.
process
1, know the ordinal number within 10.
(1) The teacher shows pictures of tapestry steps and small animals. Let the children count how many steps there are and how many small animals there are. Then put the small animals on different steps one by one and let several children count from bottom to top. Tell me which steps 10 small animals are on.
(2) The teacher took down the small animals, and asked the children of 10 to come up and put one on different steps. Tell them what animals they put, count them from the bottom and on which step, and the other children will judge whether they are right or not.
2, distinguish between cardinal number and ordinal number
(1) The teacher shows the pasted pictures of fruit bowls (they are not arranged according to the number of apples in the bowl, but can start from any number within 5), and asks several children to count how many plates there are, and then tell the order of each plate from left to right (or from the red plate). After the children count, the teacher asks several children to count how many there are in each plate, and guides the children to find out how many fruits are in the plate and how many plates are different. The teacher asks questions, some of which are as different as the first one. What's the difference? Guide the children to discuss. Then the teacher summed up: there are several different from the first one, one is that there are several things, and the other is that it ranks first.
(2) The teacher asked the children to work in pairs, holding pictures in their hands, telling each other the order of each fruit bowl, and counting the number of fruits in each bowl to further clarify the difference between several and the first one.
Step 3 do exercises
The teacher instructed the children to do exercises.
4. Turn the number and skip the grid
The teacher divided the children into groups of 10 and played checkers. The teacher first draws several groups of 10 continuous large squares on the ground, numbered from 1 to 10. The children in each group draw a digital card from the digital card in sequence, say what number they have drawn, and then jump into the corresponding grid one by one according to the numbers on the card until all the children in the group jump into the grid.
Math teaching plan for middle class: Understand the design background of activity No.2 within 10.
The children in our class pay special attention to the things around them and are always willing to discuss and share the novelty they have discovered. The house in life is also the object of children's attention. During the activity, the children compared the houses they saw together, and found that the items around us were varied and had their own uses. In the whole activity, I mainly used games and brain recognition methods, with various pictures and vivid story lines, to make the whole process closely linked and interlocking.
moving target
1. can count from one to ten correctly in different directions (up, down, left and right), can correctly express the order of objects with ordinal numbers, and can experience the relationship between cardinality and ordinal numbers.
2. Cultivate children's observation and judgment.
3. Guide children to actively interact with materials and experience the fun of mathematics activities.
4. Develop children's logical thinking ability.
5. Stimulate children's interest in learning.
Teaching emphases and difficulties
1. Teaching focus: learn to accurately identify the arrangement position of objects in different directions.
2. Teaching difficulties: determine your own direction and find a correct position.
Activities to be prepared
10 velveteen; Several digital cards; 10 room picture.
Activity process
1. Know the ordinal number within ten.
Show me a row of houses. This is the home of small animals. Count how many rooms there are. This is the second room ... who can number them and number each room?
2. Correct use of ordinal numbers
At dawn, the rooster got up. He jumped on his roof and woke his friend up. What number does the rooster stand on? Small animals get up. The teacher took the animals out of the room at will, watched xx get up in X rooms, and guided the children to say ordinal numbers.
The animals are ready to do exercises. They lined up from right to left. Who ranks first and who ranks second now? ..... once again attract the use of ordinal numbers to explain the order of animals queuing. Who ranks first from left to right? Who is the second? ...
3. Continue to practice using ordinal numbers
Let children send red flowers to small animals. To whom you want to send flowers, you must say, "I send flowers to xx in which row."
Teaching reflection
1. During the whole activity, the children maintained a strong interest, and the teacher also participated with them, which played a guiding and auxiliary role.
2. The teaching AIDS of this class are well prepared, playful and interesting, and the classroom atmosphere is active, which fully stimulates the children's learning enthusiasm.
