The design idea of "understanding more than number but less than number" 1 math teaching plan in large class
According to the characteristics of children in large classes, I guide children to know ">" on the basis that children have already known "+","one" and "=". And ""and "
moving target
1. Understand ">" and "< Understand the meaning of inequality.
2. According to the characteristics of ">" and "<", let children remember the opening direction of these two symbols through nursery rhymes and body perception.
3. Cultivate the flexibility and reversibility of children's thinking.
Activities to be prepared
1. There are 4 pictures. The patterns in Figure 1 to Figure 4 are 8 rabbits, 6 ducklings, 4 flowers and 9 dolls. 2 plates of fruit; 2 boxes of toys.
2.7 digital cards (numbers are 8, 6, 5, 7, 4, 3,10 respectively); ">,"<" = "cards.
3. A set of digital flower headdress.
4. Make the classroom a smart room.
5. tape recorders and tapes.
Activity process
1. Take Scarab Sister in Animation City as the introduction, invite children to visit the smart house, play the music from the train and introduce the topic.
The second step is to know ">".
(1) Show two figures (Figure 1 and Figure 2). The children said this number. The teacher put up the corresponding digital cards (8 and 6) and guided the children to compare the two numbers, saying that 8 is big and 6 is small.
(2) Teacher: We can put a symbol between 8 and 6, so that everyone can know at a glance which side has the largest number and which side has the smallest number. We have learned "=" before. Can you play "="? Guide children to know ">". Focus on guiding children to observe ">" like smiling at a large number with their mouths open, indicating that the number in front is greater than the number behind. Say "8 is greater than 6".
(3) Show two plates of fruit and let the children say the number. Teachers will paste corresponding digital cards (7 and 5) to inspire and guide children to say "7 is greater than 5".
The third step is to understand "
(1) Show two pictures (Figure 3 and Figure 4) to let children feel the difference of their numbers. The teacher puts on the corresponding digital cards (4 and 9) and leads out ".
(2) Show two groups of toys, let children say numbers, and paste corresponding digital cards (3 and 10) to guide children to say "3 is less than 10".
(3) inspire children to find out ">" and "
"> and" "or"
(4) Learn children's songs: greater than the number, smiling at the large number; If it is less than a number, it will be displayed to decimal.
4. play games: learn to do ">" and "
Let two children make digital flowers and wear digital headdresses. A child stands between two numbers and performs ">" with body posture. Teacher & lt takes notes on the blackboard and then asks the children to read them out.
5. Summary
Put the music of "The Train is Coming" out of the classroom, and the activity is over.
The Design Intention of Math Teaching Plan 2 "Knowing More than Number and Less than Number";
The children in my class know the equal sign, but they don't know the greater than sign and the less than sign, which has practical needs. Moreover, I think this activity is interesting, which can attract young children and have physical activities to participate in. The selection of materials conforms to the spirit of the new outline; Meet the needs of children's development and children are interested.
Activity objectives:
1, know ">" and "
2. Learn to turn inequalities into equations.
3. Cultivate the flexibility and reversibility of children's thinking and train children's ability to solve practical problems with mathematical knowledge.
Activity preparation:
1, pictures of 7 bees and 5 butterflies.
2. Pictures of four red flowers and six yellow flowers.
3. Digital cards "7", "5", "4" and "6" and ">", "
4. Two sets of digital headdresses and a set of children's operation materials.
Activity flow:
First, introduce the topic: understanding ">" and "
1, ask: "What season is it, little friend?" (Spring) "Spring is coming. Bees and butterflies fly around and come to our kindergarten. Let's have a look. How many bees have flown? " How many butterflies? "The teacher shows pictures of bees and butterflies, the children say the numbers, and the teacher pastes the corresponding digital cards.
Q: "Who has more bees than butterflies? Who is less? " "So, 7 or 5, which number is bigger? Which number is small? "
Teacher: "we can put a symbol between 7 and 5, so that people can know which side has the largest number and which side has the smallest number at a glance." We have learned the number "=" before, can we put the number "="? " Enlighten children, quote ">", focus on guiding children to observe the image of greater than number, and open their mouths to smile at large numbers. The greater than sign indicates that the number in front is greater than the number in the back. We understand the meaning of the greater than sign and say that "7" is greater than "5".
2. Q: "Where are the homes of bees and butterflies?" (in the garden), show pictures of red flowers and yellow flowers, let the children feel their differences in quantity, and lead to "
3. Teacher: "Both the greater than sign and the less than sign have an opening. They look very similar. How can we remember them? Do you have any good ideas? " Enlighten children to find out the internal law: "Children can see which number (large number) they open their mouths to, which number (decimal number) they open their mouths to, whether it is greater than the symbol or less than the symbol."
Learn children's songs: greater than the number, smile at the large number, and show the decimal number to the decimal number.
Second, performing games: learn to do ">"
Let two children make digital dolls and wear digital headdresses. A child stands between two digital dolls and indicates that the number is greater than or less than through body movements.
Play this game several times, and let the children play the greater than sign and the less than sign collectively.
Third, learn to turn inequality into equality.
Our equal number is unhappy. It says that children forget when they meet new friends, and it can also play games.
How to draw an equal sign between 5 and 7, 4 and 8?
Fourth, children's homework exercises consolidate knowledge.
1. The teacher explained the operation requirements.
2. Pediatric surgery
3. Collective inspection
Fifth, outdoor games.
Let's find friends to play games with more numbers than numbers.
