The design intention of small class mathematics teaching plan 1;
Comparison and ranking are often used in small class teaching and game activities. Combined with my sub-topic, "Putting forward questions in inquiry activities", I put straws that are common in children's life into activities, and guide children to observe the shape characteristics of straws with enlightening and targeted questions, focusing on exploring and finding ways to compare the length, that is, aiming at one end of straws can compare the length of the other end. Teachers' questions are directed at the objectives of the activity, and the principles of pertinence and openness run through the whole activity, highlighting key points, stimulating children's awareness of problems, and cultivating children's ability to constantly discover and solve problems in this process.
I. Activity objectives
1, know the length and learn to compare the length of objects.
2, you can sort from short to long or from long to short, and experience the fun of hands-on operation.
Second, the activity preparation
1, teacher: a straw; A straw is lined up from long to short.
2. Children: a number of straws with different lengths, thicknesses and colors; Each person has 3 straws of different lengths, 1 sorting card.
Third, the activity process:
1, talking about getting started, knowing straw.
(1) Show me the straw. Teacher: Look, what's this? The teacher also prepared straws for the children. Please take a closer look at what your straw looks like.
(2) Children can observe and tell freely.
(3) Teacher: What is your straw like? Young: long, yellow …
(4) Teacher's summary: The straw is long and round with a hole in the middle.
(Analysis: The activity material comes from children's life, and children have a preliminary understanding of the shape characteristics of straws. The straw was directly displayed at the beginning of the activity, which aroused the interest of children in observation. By watching and speaking, children can further deepen their understanding of straws. )
2. Perceive the differences of straws and explore ways to compare the length of objects.
(1) Teacher: I have many straws here. Please choose another one to see. What will you find?
Young: color, thickness and length are different.
(analysis: children choose the second straw for observation and comparison, so that children can feel the diversity of straws and enrich their understanding of straws through operation. )
(2) Teacher: (Length) How do you compare?
Yang: I can tell with my eyes.
Teacher: Who has a better way than seeing with eyes?
(3) Teacher: Look at the teacher's comparison. Put the straw upright on the table, one end of the straw should be aligned, and then compare the other end to see which straw is long and which straw is short. Now, please try to compare.
(4) Teacher's summary: It turns out that straws are colorful, thick and thin, long and short. When comparing the lengths, align one end of two straws and then compare the other end, so that the lengths can be compared.
(Analysis: Teachers use enlightening questions to guide children to explore ways to compare the length, and help children know that the length of straws can be compared visually to expand their experience and improve their problem-solving ability. )
3. Guide children to arrange straws from short to long or from long to short, and strengthen the proportion.
(1) Teacher: Just now, we learned the short method. Now I want to test you. I have three straws here. Please arrange them according to their length.
(2) Teacher: Who wants to compare their lengths first? Ask a child to operate it. After comparing the shortest straw, the teacher immediately lined up from short to long. (Remind to queue up from the red flag)
(analysis: pre-group operation method, strengthening sub-ratio. It is helpful for children to intuitively observe and understand the sorting method and lay the foundation for their next operation. )
(3) Teacher: Now we line up from short to long. How else can I line up? If the child can't figure it out, the teacher can directly show the queuing method from long to short.
(Analysis: Arouse children's life experience with enlightening questions, perceive another sorting method from long to short, and enrich children's sorting experience. )
(4) Teacher: Next, please compare the lengths of the three straws, and then line up from short to long or from long to short from the red flag!
(5) The proportion of children's free operation is guided by teachers. Remind children to compare the lengths of the three straws first, and then line up in turn from the red flag.
4. Show children's works.
(1) The teacher put different arrangements from short to long and from long to short on both sides.
(Analysis: Two different sorting methods are classified and placed, so that children can perceive different sorting methods more intuitively and bring different visual feelings. )
Teacher: Look, have you all lined up? If there are any mistakes, please ask the children to correct them. )
(3) Teacher's summary: Children are really capable. They can compare the lengths of three straws and arrange them from short to long or from long to short.
Reflection:
The teaching materials of this activity are novel and conform to the age characteristics of small class children. Children are interested in activities and participate in them. Activities by guiding children to observe the straw, find and say the shape characteristics of the straw, such as long and round, with a hole in the middle. Focus on guiding children to explore and find a longer method. The teacher's question is directed at the goal of the activity. Let the children aim at one end of the straw to find out the length, and then operate the method of sensing the length, which breaks through the focus of the activity. Then compare the three straws with the method of comparing lengths, and sort the straws from short to long or from long to short. Sorting on the sorting card can improve the awareness of mathematics application and cultivate children's ability to analyze and solve problems.
There are still many shortcomings in the research and development activities by grinding:
1, the teaching content is beyond the ability level of small class children last semester, so it is recommended to do it next semester.
2. The first step is to provide each child with a straw, so that children can observe and discover the shape characteristics of the straw themselves, which is more natural and open.
3. Draw a small red flag on the sorting card, so that children can queue vertically from short to long or from long to short, which is more suitable for children to operate.
4. When correcting mistakes, children can operate and correct them on the blackboard, which can not only prevent other children from waiting too long, but also better pay attention to the individual differences of children and let them find out where they are wrong.
Small Class Mathematics Teaching Plan 2 Activity Objectives:
1, understand the concept of length, learn to compare the lengths of objects and describe them in language.
2. Single-ended alignment method can be used to compare objects and classify them according to their long and short characteristics.
3. Quickly integrate into the game atmosphere to participate in activities and experience the happiness brought by the game.
Activity preparation:
1, each hand has a basket. There are two colored paper strips (the same length), two straws (the same length) and three colored ribbons (the red one is long, the green one is short and the yellow one is the shortest).
2. One piece of colored paper and two transparent open plastic bags (marked with the numbers 1 and 2 respectively).
3. Music "Red Silk Dance".
4. Venue layout: Red, green and yellow make up a dance floor.
Activity flow:
First, introduce magic tricks to arouse interest and perceive the length.
(1) The teacher does magic.
1, Teacher: Today the teacher brought a little magic trick. Open your little eyes and look carefully.
Turn two identical pieces of paper into one long and one short.
2. What is the difference in children's observation? Tell me how you know.
Summary: Our baby is great. You can see with your eyes that two pieces of paper are different, one is long and the other is short.
3. Tell your child the secret of "change".
(2) Children do magic.
1, children take two pieces of paper from the basket and learn to be little magicians.
2. Say which is long and which is short.
Second, further deepen the understanding of the length of homework activities.
(1) Compare and classify two objects.
1, please take out two straws from your own small basket for comparison.
Tell me how you found out which is long and which is short.
2. What can I do besides seeing with my eyes?
Guide children to compare with one end alignment method. (You can compare horizontally or vertically. )
3. Send a straw home. Put the long one in 1 bag and the short one in 2 bags.
Step 4 check.
The teacher took out a straw in a bag and checked whether they were the same length by aligning one end. In another bag, please ask a willing child to check it.
(2) Try to compare and classify three objects by single-ended comparison method.
The child took out three ribbons from the basket.
Choose your favorite ribbon.
Try to compare and say whether you have a long one, a short one or the shortest one.
Please go to the red dance floor for the long ones, the green dance floor for the short ones and the yellow dance floor for the short ones.
Third, the game: ribbons float.
Play "Red Silk Dance", jump up with the children and dance ribbons.
Class record:
First of all, small magic imports.
Teacher: Today the teacher brought a little magic trick. Keep your eyes open and observe carefully.
Teacher: (showing colored paper) This is a yellow paper (said by the children).
I'm going to turn it into four identical notes. (Take two)
Teacher: Look, I'm going to change. ...
Teacher: Are they the same now?
Yang: It's different.
Teacher: What's the difference?
Yang: This one is small. (pointing to the short one)
Yang: It's shortened.
Teacher: Great! Yes, one of them is shorter. How's this?
Yang: No change.
Yang: It's getting longer and longer.
Teacher: Actually, this hasn't changed. Longer than it. We call it a long note and a short note a short note. Say it with the teacher-
Teachers and students: long notes, short notes, long notes, short notes.
Teacher: Do you want to know how this magic works?
Yang: Yes.
Teacher: Look carefully! This finger quietly pressed down the paper on it, and then quickly picked it up. You also come to change!
Teacher: Gently take out two pieces of paper from the basket. Change together and then guide individual children.
Teacher: You have all become little magicians! Hold up the note and say which is long and which is short.
Small class mathematics teaching plan 3 activity goal
1, in the attempt, you can compare the length by visual inspection and one-to-one correspondence, and experience your sense of success in finding results.
2. Learn to obey the rules of the game.
3. Improve children's observation ability by comparing the lengths of similar objects.
4. Be able to compare and distinguish the lengths of objects.
5. Learn to distinguish the length of objects by juxtaposition.
Activities to be prepared
1. Basket (one for each person), straw, ribbon, (two for each person, one long and one short)
2. tape recorder, musical bird flying, Wahaha and rabbit jumping
3. Headdresses of rabbits and monkeys (both have tails, of which the rabbit's tail is short and the monkey's tail is long)
Activity process
1. Show things to arouse children's interest. Today, the teacher has prepared many interesting things for the children, but before you play, the teacher has a requirement that you should carefully look at the characteristics of these things when you play. What do you think of them?
2. Everyone has a bag full of prepared items, and children are free to try to find problems.
Let the children discuss the problems found after 3.2 minutes.
4. Make a request and guide the child to try again. Now, please take out the same things from your bags, play with them, compare them and see what you can find this time.
Children speak out their findings.
Show me the tape. Just now, the children were very clever and told all the problems they found. Now look at what's in the teacher's bag. .
Look at the stick and tell the children what they see.
The teacher concluded: the redundancy here is long. Show me this word: long. Children sing and read.
What's not here is short. Show me the word: short. Children sing and read.
End the activity
1, game: listen to the signal and do the action. The teacher said dragon, and the children gestured with two hands. At the beginning, they took their children to do it. Teachers talk short, and children use their hands shorter.
2. Game: Watch the performance. Now, there are two small animals performing for the children. Let's watch them together, shall we? Listening to Wahaha music, the child left the position and went to the front.
The teacher has a request, that is, to see the small animals coming out from behind clearly. Whose tail is short? Now please get ready for the children. The little animals are going to perform.
The teacher played the role of rabbit and monkey in headdress.
After the children answer "Bunny", play the music "Bunny Jump" to lead the children to learn how to jump.
The children are all great. Now let's be rabbits and pull out radishes.
