Mathematics teaching activities in middle class 1
Design intent:
Graphics can be seen everywhere in children's real life. All kinds of objects in the world are made up of various shapes and their variants. When children are in small classes, they know circles, triangles, squares and rectangles. When we show children all kinds of graphics, they can spontaneously spell out many objects with childish hands. In order to satisfy children's strong desire for exploration and knowledge, this activity is specially designed for children to better grasp the basic characteristics of graphics and develop their imagination.
Goal:
1, consolidate children's grasp of the basic characteristics of circular triangle, square, rectangle and trapezoid.
2. Cultivate the flexibility of children's thinking, and develop their hands-on operation ability and unity and cooperation ability.
Prepare:
1, learned various graphic features.
2. Graphic cards of various sizes, the number of small baskets is the same as the number of children, chopsticks, wool, pens and drawing paper.
3. Self-made "paths", carved with graphic "pits" of different sizes, and turned the carved graphics into paving "stones".
Process:
First, "Finding Friends" music enters the activity room, and when you find a friend, put your shoulders on it.
Second, introduce scenarios to stimulate children's interest in activities.
1, let's travel to the graphic kingdom together, get on the bus and go!
2. Here we are. What is the sign? What are the numbers? How many _ _ shapes are there?
3. The graphic kingdom is here, get off! Look! There are many colored stones over there. Let's pick one we like best.
4. Guide children to observe, encourage children to communicate while operating, and boldly introduce their favorite stones (colors and shapes).
Third, paving stones
1, "There is a road ahead, why are there so many pits? What shall we do? Let's fill the pit with the picked stones! "
2. Children can operate freely-embed the found "stones" into the corresponding abnormal "pits" one by one.
3. Find the problem-"The stone is almost gone, but there are still pits that have not been paved. What should I do? "
4. Children undergo reoperation
5. "The teacher found that this stone is very special, and it is put together with stones of two colors." Ask individual children to introduce their own methods.
6. Guide children to find ways to cooperate and pave all the "pits" with their own "stones".
Summary: Several numbers can spell a new number.
Fourth, play games with graphic babies.
(a) children's operation, put all kinds of graphics.
"The graphic baby has prepared chopsticks and thread for the children. Please choose the materials you like and spell out your favorite graphic baby. "
Middle school mathematics teaching activities II
Relatively thin activity target:
1, through different methods, distinguish the thickness of 2-5 objects and sort them.
2. Cultivate children's ability to observe and compare.
3. Experience happiness through classification, cooperation and comparison.
Activity preparation:
Activities of boards, books, scarves, paper, socks, towels, biscuits, shoe boxes, drinks, building blocks and baskets:
First, visual inspection.
1, Teacher: What kind of coats do the children wear in winter (thicker than what you are wearing now)? What about what you are wearing now (thinner)?
Show me a board: I have a board here. Do you think it is thick or thin?
Teacher: Then I'll take out a piece now. Is this board thick or thin now?
Summary: It turns out that one thing can't be compared, and two or more things are thicker.
3. Teacher: How do you know the thickness of this board (with your eyes) Teacher: Your small eyes are so bright that you can know the thickness at a glance.
4. Show it to the bookseller: Then tell me again who is thicker or thinner in these two books. Teacher: Please come up and point. How do you know? 5. Show the shoe box. Teacher: Hey, how about these two boxes? Please point them out. In this way, you can compare the thickness of things through your own eyes.
Second, touch
1, the teacher shows the scarf Teacher: It's cold. What kind of scarf should I wear? Please think about it. Which one should I wear? Teacher: Do you all think it is this thick? Teacher: How do you know? Teacher: By the way, you can touch it and compare it.
2, the teacher let the children touch, come up to distinguish the teacher: Mr. Jin let the children touch, see which one is thick and which one is thin: just now we can touch it with our own hands and compare the thickness of the object.
3. Put two things with different thicknesses under each chair Teacher: Teacher puts a basket under each chair of your children. Please compare the contents of the basket, and put a purple time sticker on the thickest thing. The pasted children will send the basket here and remember where to put it. The teacher will check 2-3 items.
Summary: Our children are great. They can compare the thickness of objects by touching them.
Third, parallel comparison.
1, the teacher showed two pieces of soap with inconspicuous thickness (on the table and on the floor). Teacher: Then please have a look. Who is thicker than these two bars of soap? Teacher: Wow, some people think it's so fast, others think it's so fast, whose ass is thicker? Please try to compare.
Teacher: Well, that's great. Your method is really good. You compare two pieces of soap together. Teacher: Hey, there's a bar of soap. Is it thicker or thinner than the soap here? Teacher: How to compare? Teacher: How to compare? Tell me whether it is thicker or thinner.
2. Show me the cookie box Teacher: Who is the thickest and thinnest of these three boxes of cookies now? Please compare with the teacher: What method do you use to compare and summarize: For some objects whose thickness is not obvious, we can use the method of side-by-side comparison.
Fourth, supermarkets.
Show things of different thicknesses Teacher: Just now, our children have learned how to put things thicker, haven't they? There is a clerk in the supermarket who wants to ask you for help. Would you like to? It turns out that the supermarket has a lot of things of different thicknesses to sort out and find a home by yourself. You see, there are supplies area, beverage area, food area and toy area. Teacher: Please ask each child to take a product later, find their home first, and then compare them.
Check: Teacher: Let's see if they are arranged correctly. In this group, this is the thinnest and this is the thickest. The teacher checked and summarized in turn: Today, we learned a lot of thick and thin methods, which can be seen with eyes, touched by hands, or compared together.
5. search, operator: there are many things in our home and classroom that can be used to compare the thickness. Now let's go to the classroom and compare.
Activity expansion:
Find your own clothes, separate the thin ones from the thick ones and put them away.
Middle school mathematics teaching activities 3
Activity goal: to know the ellipse and perceive its basic characteristics.
Activity preparation:
Teaching aid: a circle, an ellipse and a piece of paper.
Learning tools: a circle and ellipse with the same size as a human hand, a piece of paper (the length is the same as the diameter of the circle); The first and second groups, coloring the ellipse; In groups 3 and 4, the most points are marked with "_". Groups 5 and 6: Look at the symbols and fill in the dots.
Activity flow:
First, group activities 1, know the ellipse.
Show the oval shape. "Is it round?" (No) "Where do you see that it is not round?" "Let's have a competition together." Guide children to compare the two figures in front of each other and make sure that the ellipse is longer than the circle. "What's the name of this character?" (Ellipse) "Besides being longer than a circle, what's the difference between an ellipse and a circle?" (Guide children to fold the circle in half from left to right, then fold it up and down, and measure the two folds with a piece of paper to verify that the two folds of the circle are the same length; Then guide the children to fold the ellipse in half up and down, and measure the crease again to verify that the crease of the ellipse is not the same length.
2. Summarize the characteristics of ellipse.
"The two ends of the ellipse are longer than the circle, and the folds folded up and down are different in length from those folded left and right." 3. Name the oval objects in daily life.
"What other oval things can you see at home and kindergarten?" Second, the group activity 1, the first and second groups, color the ellipse.
"Find the ellipse and color it with the same color." 2. The third and fourth groups give the most ideas. 3. The fifth and sixth groups look at the symbols and fill in the dots.
Thirdly, the activity evaluation shows the homework of individual children to color the ellipse.
Middle school mathematics teaching activities 4
Activity objectives:
1, distinguish the left and right sides of your body with yourself as the center, and distinguish the number of objects on your left and right sides.
2. Knowing the difference of reference, the left and right directions will also change.
3. Develop children's spatial orientation perception and judgment ability.
Activity preparation: animal pictures
Activity flow:
First of all, guess the import and feel your own left and right.
1, the difference between left and right
Teacher: Today, the teacher brought a riddle to the children: a small tree with five branches, no leaves and no flowers. It doesn't talk from morning till night, and it is indispensable for writing and drawing. Oh, so many children raised their hands. Do you know that the hand they raised is-(right hand)?
Teacher: Yes, we usually raise our right hand and hold your right hand high. (Teacher checks) What do you usually do with your right hand? Teacher's summary: The right hand usually holds chopsticks, pens, brushes teeth, writes and so on. Then raise your left hand and talk about what it usually does.
Conclusion: Yes, the left hand and the right hand are a pair of good friends on us. Only when the left hand and the right hand cooperate with each other can things be done better and faster.
Step 2 look for it
Teacher: Think about it. What good friends do we have? Like hands, they are left or right.
3. Competition
Teacher: Just now, the children found it quickly and well. Now the teacher wants to invite our good friends to play a game. This game is called "I say you say you do it". Let's have a try. See who has the sharpest little ears and the fastest response.
Teacher: Come, come, come, raise your right hand. Child: My right hand is up. (One by one: raise your left hand, clap your right leg, touch your left ear, making it more difficult: touch your left ear with your right hand, clap your right leg with your left hand, and so on.
4. Consolidate your familiarity with the left and right.
Did the children have fun just now? Actually, whenever there are people or things around us, can you tell me what is on your left? Or who is sitting? What about the right? Practice speaking (say a word with left and right)
Second, explore communication and be familiar with the relativity and absoluteness of the left and right.
Teacher: Five small animals saw that we were having such a good time, and they also joined in the fun. Look who's here. Show pictures of five small animals. )
Ask questions:
1. How many small animals are there? Who is on the far left? Who is on the far right?
2. Who is the third one on the left?
Who is the fourth one on the right?
4. Where is the kitten? (You can look from the left or the right)
5. Which side is the bird? Follow-up: On whose left? Whose right is this?
Practice saying: The bird is on the left of () and on the right of ().
6. Summary: We look at different standards, and the left and right directions are different. For example, for example.
7. Practice saying: Whose right I am and whose left I am.
Third, contact with life and control application.
Today we learned a new skill and got to know the left and right. In fact, we often use left and right in our lives. Think about it, we have to go up and down the stairs (). Then when the teacher takes the children for a walk, see if you can do what you say.
1, line up.
2. Listen to the password: turn left and turn right. Take three steps to the left and three steps to the right.
3. change direction and know the left and right.
4. Take the stairs to remind children to pay attention to safety and walk on the right.
Middle school mathematics teaching activities 5
Teaching objectives
1. Review the counting method of pomegranate receptacle in closed arrangement.
2. Try to record the classification results by statistical methods, and be willing to introduce your own calculation results in concise language.
Teaching preparation
Have preliminary contact with the closed number; One sorting box, one statistical table and one pen; Pomegranate flower trays picked up by children, one for each group. "Pomegranate grows up quickly" operation diagram: a small pomegranate, a green pomegranate and a mature pomegranate are held as pomegranate flowers in turn.
teaching process
1. Review the counting method of closed arrangement.
(1) Count the petals of pomegranate flower Tori.
Teacher: Please ask each child to take a pomegranate receptacle from the plate and carefully count how many petals it has. How did you figure it out?
Summary: When counting petals, you should first determine a starting place, you can mark it, and then count one petal at a time, so that you can know where the counting can end without missing or repeating the counting.
(2) Check each other and re-determine the number of petals of pomegranate receptacle.
Summary: The number of pomegranate petals is different.
2. According to the number of petals of receptacle.
(1) Use the classic dialogue of the story "Three Butterflies" to illustrate the operation requirements. For example, "Room 4 said,' Please come in with four pomegranate flowers, not others. """No.5 said,' Please bring five pomegranate petals and nothing else.' "
Category box:
(2) Children's operation: Send five pomegranate flowers to the corresponding digital sorting boxes according to the number of petals in the receptacle.
(3) Show the children to each other, introduce their classification results, and talk about how many pomegranate flower trays were invited in Room 4, Room 5, Room 6 and Room 7 respectively.
3. Try to use statistical methods to record the classification results.
(1) Teachers and children discuss ways to establish recording.
Show me the statistics: let the children carefully observe what they see on the recording paper. Guess what they mean respectively?
(2) Children's operation, using dot symbols to record the number of pomegranate receptacles with different petals in the sorting box.
Teachers' itinerant guidance: pay attention to the methods and steps recorded by each child and understand the children's problem-solving strategies.
(3) Guide the children who finished first to observe their own recording paper and find out the most pomegranate flower holders and the least pomegranate flower holders.
4. The game "Pomegranate grows up quickly".
(1) Teachers and children establish the rules of the game: briefly state the number of pomegranate receptacles with different petals, and the pomegranate receptacles will grow up slowly after correct statement. (Children express the number of pomegranate receptacle recorded by themselves in complete language. For example, there are 65,438+0 5-petal pomegranate flower receptacles and 3 6-petal pomegranate flower receptacles ... After children tell stories correctly, they demonstrate the growth process of pomegranate with drawing teaching AIDS. )
(2) Communicate with each other and learn to express their calculation results in correct language.
(3) Play the game "Pomegranate grows fast", and children will tell it in turn, and show the process of pomegranate receptacle growing slowly through pulling.
