Mathematics teaching plan for middle school class: a comparative study of the goal of 1 activity.
(1) can compare the thickness and width of an object.
(2) Willing to tell the results of comparison in language and get the pleasure of exploration.
(3) Understand the application of numbers in daily life, and preliminarily understand the relationship between numbers and people's lives.
(4) Cultivate children's good operating habits of cooperative and orderly operation.
Key points:
Learn to compare the thickness and width of objects.
Difficulties:
Tell the result of the comparison
Activities to be prepared
Prepare some objects with different thickness and width, such as pencils, wool, building blocks, wide and narrow cardboard, etc.
Activity process
(1) Introduce the story of the Monkey King and guide children to observe the teacher: Do children know the Monkey King? . The lesson plan comes from: big; Test the teacher's network. The Monkey King's golden hoop can make it thicker and thinner. Today, the teacher will also teach you this skill: .........
(2) Observe the object, show the wool and pencil, and distinguish the thickness. Teacher: Look at what the teacher has in his hand. Let's compare which is thicker. Which is better?
Children: ... (Guide children to say that xx is thicker than xx and xx is thinner than xx)
(3) Display colored cardboard and distinguish the width. Teacher: Look at the cards in the teacher's hand, children. Let's observe and compare. Which is wider? Which is narrower?
Children: ... (Guide children to say that xx is wider than xx and xx is narrower than xx)
(4) Compare A. Play games and let children find an object. Compare, how do you know if it is thick or thin?
B, please be tolerant of the two groups of children (guide the children to say that they know better)
C. Summary: Our children are all great, and they have all learned the skills like the Monkey King. We know that we can master the ability to distinguish thickness and width by comparison.
Activity expansion
We children can also compare the thickness and width of objects during the game and make records when we get home.
Teaching reflection:
Through this teaching activity, I learned that children's mathematics is very weak. In order to make them interested in math, I'm going to add more games in future math activities, so that children can have fun and learn from each other while playing. Really let children become the masters of learning and constantly improve their independent inquiry ability.
Middle school mathematics teaching plan: comparison and discussion. 2 Activity objectives:
1, which can judge and compare the thickness and width of objects by visual inspection.
2. Willing to express the results of activities in words.
Key points and difficulties:
The thickness and width of an object can be judged and compared by visual inspection.
Activity preparation:
1. Arrange some items with different thicknesses and widths in the class environment, such as ropes, balance boards, cylindrical building blocks, etc.
2. A picture of an elephant and a picture of a giraffe were drawn by a child.
Activity flow:
First observe the animal pictures and distinguish the thickness.
1. Show pictures of elephants and giraffes to guide children to observe. Question: Compared with giraffe, whose legs are thicker and whose legs are thinner? Theory: Elephants have thick legs and giraffes have thin legs.
2, expand experience: know what is thick accumulation and thin hair. For example, straws are thick and thin.
Second, observe the board and distinguish the width.
Guide children to cross the bridge with elephants and giraffes, and compare the width and narrowness of the bridge deck.
Third, observe the objects in the class environment and find the thickness.
Ask children to give relevant examples, such as some pens are thick and some pens are thin.
Fourth, the game: comparative search.
1, divide the children into two groups in the outdoor field: the teacher gives instructions, such as "hold a thick trunk." One group of children found a thick trunk and hugged it, while the other group observed and evaluated whether it was correct. The game continues: find a thin trunk and walk on a wide bridge and a narrow road. ...
2. After several rounds, the two groups communicate.
