Mathematics Teaching Plan for Large Classes: Simple Laws 1 Activity Objectives
1, guiding children to discover simple laws (natural phenomena and specific laws) between things through observation.
2. Cultivate children's good habits of careful observation and diligence.
3. Experience the fun of thinking training.
Activities to be prepared
1, teaching aid preparation: examples of three arrangement rules; "wonderful book" courseware
The cover is rainbow. From page one to page seven, there is a red strawberry, two oranges, three Huang Xiangjiao, four green watermelons, five blue apples, six blue plums and seven clusters of purple grapes. Pictures (from children to teenagers to adults to the elderly; From tree buds to small trees to big trees; From eggs to chickens to hens and so on. ).
2. Preparation of learning tools: several sheets of homework paper, markers, triangles, circles and squares.
Activity process
First, the beginning part
Dialogue guide: Did the children find anything special about our seating order today? (A man and a woman) There is a group of graphics, and the arrangement order of babies is similar to ours. Let's see who they are.
Second, the basic part
1. displays the sample bars with three arrangement rules in turn. Let the children read what the figure on each sample strip is and what the rules are.
(1) Show the model room ○○○○○○○○○○○○○○○○○○○○○○○○○○9 How can they stand at the back of the line? Their ranks are neatly arranged. We can see more clearly with letters. A stands for circle and B stands for square. What are their arrangement rules? (Guide the children to group ab ab ab, and the teacher will record it at the bottom of the sample column to help the children sum up the rules. )
(2) Show sample terms ○ □□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□ How are they arranged? What should they do after the team? What are their arrangement rules? (Guide the children to group abb abb abb, and the teacher will record it under the sample column to help the children sum up the rules. )
(3) Similarly, display sample strips ○△△ strips ………………………………………………………………………………………………………………….
2. Play the courseware to guide the children to observe the "wonderful book" and find out the rules in the book.
(1) Guide children to observe the "wonderful book" from the cover to the third page. The cover is a rainbow, and the colors are red, orange, yellow, green, cyan, blue and purple in turn; On the first page is a red strawberry; The second page is two orange oranges; The third page is three Huang Xiangjiao. Let the children guess what the next pages are in turn and how. Guess the number of fruits according to the page number and the color of fruits according to the color of the rainbow. The teacher affirms the child's guess, and then guides the child to read the big book completely and find the rules in the book. The number of fruits, like the number of pages in a book, is from less to more; The color of fruits is the same as that of rainbows, ranging from red to purple. )
(2) Guide children to talk about regular phenomena in life. There are many regular phenomena and things in our life. For example, the law of people's growth (showing pictures) is to grow up slowly from childhood and finally get old. The same is true of plants (show pictures). Trees grow from buds to saplings, and finally become big trees ... encourage children to communicate with their peers about the laws and phenomena of things they know.
3, children's operation activities (free choice of operating materials).
(1) Look at the picture to find the rule, and indicate it with letters. (2) Paste the graphics according to the arrangement rules. (3) Arrange the pictures according to the law of animal growth. (4) Arrange the pictures according to the law of plant growth. The children show the operation results and the teacher evaluates them.
Third, the conclusion part.
Teacher's summary: Today we learned several simple laws, which can be seen everywhere in our lives. We can find them with a little attention. Let's go outside and see what laws are around us, shall we?
Mathematics teaching plan for large classes: simple law 2 teaching objectives;
1, through the orderly arrangement of items, students can initially understand the simple arrangement law and point out the next object according to the law.
2. Stimulate the sense of innovation through activities such as coloring and placing learning tools.
3. Make children realize the value of mathematics in mathematics activities and enhance their interest in learning mathematics.
4. Cultivate children's habit of speaking while operating.
5. Be willing to participate in activities and experience the fun after success.
Teaching emphases and difficulties:
Children can discover the laws of things through practical activities.
Children can create a regular arrangement by themselves and guide them to find six regular teaching AIDS, six learning tools and six different animal learning tools from the aspects of color and shape.
Teaching process:
First, introduce conversation and perceive the law.
1, children, we are going to have a party. We are going to spruce up the classroom. Do you want to see it? Please look at the big screen.
2. Courseware shows the theme-children dancing in the beautiful classroom.
Teacher: Please observe carefully and tell me what you see. What did you find?
You 1: There are colorful flags, lanterns and flowers.
Young man 2: There are many children dancing.
Teacher: Are these colorful flags, flowers and lanterns everywhere?
Health: No, there is a sequence.
Teacher: They are all arranged in a certain order, and they are all arranged regularly. In fact, we often encounter laws in our daily life. In this class, we should look for the laws in life from the perspective of mathematics.
Second, guide exploration and understand the law.
1, courseware shows colorful flag map.
Teacher: Let's look for the arrangement of colorful flags first.
Colorful flags appear alternately in red and yellow, and the last side has no color. )
Teacher: Guess what color this flag will be.
Young 1: It's yellow.
Youth 2: Next to it is the yellow flag.
Teacher: Guess the yellow flag and see if it is right (click the mouse, the last flag turns yellow and the children cheer). What a good guess! what do you think?
Teenager: Because the small flags have been placed in red and yellow order, the yellow flag is behind the red flag.
Teacher: If you are allowed to group the colorful flags according to the rules you found, you can see the arrangement rules of the colorful flags more clearly. How are you going to divide it? Who wants some? Why do you want to divide it like this? (Small flags are repeated in groups, and the law is particularly clear. )
2. The courseware shows colorful flowers, lanterns and children's queues.
Teacher: We found the rule of colorful flags. What are the rules for the arrangement of colorful flowers and lanterns and the children's team? What color will the next lantern be? Is the next child a boy or a girl? How to group? Tell your deskmate the secret you found quietly. (Children think and communicate. )
Teacher: Who wants to announce your findings to the class?
You 1: The colored flowers are arranged in the order of green, purple, green and purple, so the next flower is green.
Teenager 2: The lanterns are arranged in the order of purple, red, purple and red, so the next lantern is purple.
Young 3: Children are always in the order of boys and girls, so the next child is a girl.
How to group? (According to the students' answers, click at will, and the correct group will appear. )
3. Summary: Colorful flags, lanterns, colorful flowers and the arrangement of children's teams are all arranged in groups in a certain order. We can say that this arrangement is regular.
Third, intellectual breakthrough, regular use Teacher: The children are really capable, and they found the arrangement rules of colorful flags, colorful flowers and lanterns at once. Next, we will play a breakthrough game. Do you have confidence?
(1) Level 1: Guess what's next? Show the courseware, and the children can answer what is the rule and what is the next one. ) The teacher asked: What's the difference between the first group and the second group?
Summary: (1) One is a group of two and the other is a group of three;
(2) A ruler with only one color, one color and one shape.
(Key points: By contrast, let children realize that rules can be single-layer or multi-layer, and they can be in groups of two or three, thus realizing the diversity of rules.
(2) The second level: application.
(1) Show the courseware Teacher: The students' performance is very good. Can you color according to the rules next? At the same time, the courseware gives an example 3.
Teacher: Who will report how you draw it? (Specify sub-report)
(2) Teacher: Do you still want to do a coloring contest?
Teacher: Question ③ Who discovered other laws? (Guide students to discover rules from two aspects: color and shape. )
(3) See who can find it quickly. Let the children look at the courseware, find out what the next picture is and give feedback.
(4) Active classroom atmosphere, looking for rules in songs.
Show the courseware and the music "Happy Clapping Songs", and ask the children to sing and dance.
Fourth, contact life and find the law.
1. Regular things often give people a sense of beauty. Let's enjoy the beauty of law together. Show pictures in the courseware.
Law is everywhere in our life. Can you find the laws hidden around us? Show the courseware and find out the laws hidden around us. The students answered. Ceiling, floor, prizes on the blackboard, your own clothes in the classroom. ) 4. Hand shaking: (Little designer) We already know some rules. Can children create new rules by themselves? Put it out with school tools?
Students pose, teachers patrol and praise in time.
Report. Courseware shows students' works.
5. Are you happy with the class summary? The teacher is also very happy. Did you learn anything from this course? Who will tell us what you have gained?
Teacher: Besides looking for patterns according to the colors and shapes of things, there are many patterns of pictures, actions and sounds in our lives. Children who are diligent in thinking and observant will surely find these wonderful patterns. As long as we are good at observing, we will find many beautiful things. As long as we work hard to create, our life will be better!
Teaching reflection
I designed this activity based on the universality of laws and the characteristics of everything. The activities were conducted in the form of interesting games. The activities were full of joyful atmosphere and entertaining. Children find out the law by clapping their hands and feet, finding out the law of increase and decrease by observing pictures, and finding out the law of color and shape by using pendulum graphics. Finally, in the process of piercing beads, children should grasp the universality of laws and cultivate divergent thinking ability.
