1 activity goal of "sorting by length" in small class mathematics teaching plans;
1, which can distinguish the length of an object within 5.
2. Experience the sequence relationship of objects from long to short or from short to long in operation activities, and try to sort by length.
3. Make children willing to participate in group activities.
Activity preparation:
Long stick; Five different lengths of wool; Five pens of different lengths.
Activity flow:
First, play online games.
Giraffes have long necks and sika deer have short necks. Uncle elephant has a long nose, and pig has a fat nose and a short nose. White rabbits have long ears and kittens have short ears. The monkey's tail is long and the rabbit's tail is short and short. Please also tell me what is long and what is short.
Second, compare the game and review the length.
Each child takes a long stick, compares it with the children around him in turn, and says in words, "My long stick is longer (shorter) than yours.
"Guide children to observe and compare, and the length of perception is relative.
Third, teachers and children * * * in order of the length of exploration.
Long stick dolls also want to ask children to compare their lengths and queue them up. The teacher took out five long sticks and demonstrated the sequence of five long sticks from short to long.
The teacher brought a group of good friends to the children. They are good helpers for children to learn. We'll rearrange them. (children's operation exploration)
Fourth, group activities.
The first group: operating long sticks, sorted from long to short or from short to long, and the direction is not limited.
The second group: arrange the wool in long and short order, and the direction is not limited.
The third group: operate the pencil and experience the sequence relationship of length according to the sequence of length.
End of activity:
Lead children outdoors to find objects in order of length.
The activity process of "sorting by length" in small class mathematics teaching plans 2;
1, game import, experience perception ordering law.
Introduction: "Today, the' small rescue team' of our class was established. We want to help some small animals in need. Now let's go to the forest and see if there are any small animals in need. "
When the background music is playing, the children follow the rhythm.
① Set the scene of the garden and pond, let the children greet the flowers and frogs, and experience the regular sorting.
A Greet the little flowers in the garden according to the rule of "red flowers are good, yellow flowers are good, red flowers are good, yellow flowers are good …".
Imitate the frog in the pond. Instruct children to greet frogs according to the rules of "See big frogs scream loudly, see small frogs scream quietly, see big frogs scream loudly, see small frogs scream quietly …".
2. Set the scene skillfully and perceive the regular order of colors.
(1) Scene setting: Lin ... When the phone rings, there comes the voice of mother rabbit: "Little rescue team? I am a mother rabbit. A wolf with bleeding right foot destroyed many small animals' houses and took my little rabbit. Can you help us? "
(2) Guide children to find the regular order of small animal footprints and draw conclusions through reasoning and judgment.
Question: Which is the footprint of the injured wolf? Teachers and children discuss and reason together.
Default conclusion:
Black footprint → red footprint → black footprint → red footprint ... The purpose is to take away the footprints of the big bad wolf.
③ The conclusion of children's practical reasoning. Guide children to follow footprints, track wolves and rescue white rabbits.
3, scenario exploration, practice and experience the regular ordering of graphics.
(1) Help "Rabbit Find Home" children observe and find the way to the rabbit's home. (According to road signs: red square, blue circle, red square, blue circle rules).
Question: Please find the way to the rabbit's house.
Guide the children to find the way to the rabbit's house according to the law.
(2) Find the damaged road in practical experience and further perceive the law. (illegal)
Teacher: The rabbit's way home has been destroyed by the hateful wolf. We should help the rabbit repair the road home first, and then send the rabbit home.
Children * * * Discussion: How to find the missing graphics according to the complete road surface?
Presupposition conclusion: After defining the law of road signs, guide children to find out the missing graphics and then start operation.
③ Cooperate with each other to build a "colorful road".
A. cooperate with each other and build together.
B, teachers tour to guide individual children with weak ability.
Focus on guidance: guide children to observe the law of road signs, find out and complete the missing pavement.
(4) * * * Check the paved road and send the rabbit home.
4. Teacher's summary: There are still many items sorted by law around us. Please pay attention to observation and look for more rules.
Activity expansion:
1, doll house: regularly floor, wallpaper and decorate doll house.
2. Art design area: draw "clothes and towels" and color them according to the rules, and make colorful "lollipops" with colored mud. Children with strong abilities can choose three colors to arrange.
3. Operating area:
(1) Wear necklaces for dolls in the Dollhouse according to the rules of color or shape and size.
(2) Hanging curtains: Use shapes, patterns and colors according to the rules.
4. Building area: "Building new houses for children in disaster areas" is carried out in a free order according to the laws of graphics and colors.

Small Class Mathematics Teaching Plan "Sorting by Length" 3 Activity Objectives
1, stimulate the interest in sorting, and boldly say the sorting results in language.
2. Cultivate the ability of observation, comparison and operation.
3, can skillfully according to the difference of object length for positive and negative sorting.
Activities to be prepared
1, Courseware-Mathematics: [3-2] Comparative Concept; [3- 1] comparison concept.
2.4 sticks of different lengths; Eat hawthorn strips.
Activity process
First, import
1, arouse children's emotions.
Teacher: The teacher is going to treat us today. Look! What is this? (long hawthorn roll)
Are these two hawthorn strips the same length? (same length)
The teacher cut one of them into small pieces for a child to taste.
2. Look, what has changed? (one is long and the other is short)
Then, the teacher will cut a long piece and give it to the children to taste.
(until both of them are finished)
Second, expand
1, children are free to explore and organize sticks.
Ask the children to compare the length of sticks, arrange a row of sticks, and actively explore the sorting method. The teacher observes the children's mastery of sorting.
2. Teachers use courseware to sum up the sorting methods with children.
Ask children to watch the courseware: 3-2 comparative concepts
(1) Compare four objects first, find out the longest and shortest, put the shortest in front and the longest in the back.
(2) Then compare the lengths of the other two objects, put them in the middle in order, and say: I queue the objects in the order of shortest, short, long and longest.
Please see the courseware: 3- 1 comparative concepts.
(3) Let children do reverse sorting on the basis of forward sorting.
3. Guide children to discuss: Why are the two sorting methods different?
(1) The positive sort is from short to long, and one is longer than the other.
(2) The reverse sort is from long to short, one is shorter than the other.
(3) Encourage children to use language boldly.
Third, the end.
1, please arrange your children freely, and the teacher will give individual counseling.
2. The teacher's summary ends naturally.

Small Class Mathematics Teaching Plan "Sorting by Length" 4 Activity Design Background
In a regional activity, I found that children can distinguish the lengths of two objects well, but they can't distinguish the lengths of multiple objects well, so I designed this lesson.
moving target
1, which can distinguish the length of an object within 5.
2. Experience the sequence relationship of objects from long to short or from short to long in operation activities, and try to sort by length.
3. Willing to participate in group activities.
4. Cultivate children's comparative judgment ability.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Teaching emphases and difficulties
Key points: experience the sequence relationship of objects from long to short or from short to long in operation activities;
Difficulty: Can distinguish the length of objects within 5.
Activities to be prepared
1, teaching aid preparation: 5 pens with different lengths;
2, school preparation: long sticks; 5 ropes of different lengths; 5 pens with different lengths;
Activity flow:
1, warm-up activities:
Teachers and children say hello to each other.
Online games: teachers and children read children's songs while walking, but teachers say it, or teachers and children say it together;
2. Group activities:
1) Teachers and children * * * Sort by length by exploration.
Creating situations: Teachers bring a group of good friends to children, who are good helpers for children's study. Let's arrange them first. The teacher took out five pens with different lengths, and arranged them in the order from long to short.
Guide children to observe from top to bottom and experience that one pen is shorter than the other; From bottom to top, the experience pen is longer than one;
2) Children's operation exploration:
Teacher: "Long stick babies also want children to line up for them."
Children take out long sticks and arrange them in order from short to long, showing the sequential relationship of sample length.
3, group activities, the teacher observes the children, after the operation is completed, guide the children to tell how they sort the items.
The first group: operating long sticks, sorting from long to short or from short to long, and the direction is not limited;
The second group: arrange the ropes in order of length and direction;
The third group: operating pens, sorting by length, and experiencing the sequential relationship between lengths.
4. Game activities: the game is "ironic", the teacher says "the article is long" and the children say "the article is long"
The product is short, and the faster the speed, the better. For example, the train is long and the car is short.
5, exchange summary, tidy up the school tools:
The teacher instructed the children to tidy up the school tools as required.
Activity expansion:
1. Complete the activities on page 13- 14 of the workbook;
2. Play the game of "eating sticks". The children are in groups of three, each with three long sticks of different lengths. Three children say "one, two, three, out" together, and each child takes out a long stick, which is relatively long. The long eats the short, and the shortest can eat the longest. Finally, look who has more sticks left.
Teaching reflection
This lesson is well designed in grasping the teaching materials. Links are suitable for children's age characteristics. In the interaction between teachers and children, children devote themselves wholeheartedly and have high interest. Mathematics is to serve life. Children have mastered the method of distinguishing length in operation and game, and understood the relationship between length and order.
In the operation of children's grouping, the individual differences of children are ignored, and the children who are slow to accept are not given timely support and help. In future teaching activities, emphasize and implement children's individual differences.
concentrate on
If I take this course again, I will find children who can't master it well in operation, and focus on strategy in the game so that all children can master it well. In addition, the one-day activity will extend this activity to all links, with random education and guidance.
