Creative bell noodles, hand -made three -dimensional models ... Look at this group of elementary school students to play "cloud mathematics"

How to play mathematics during the study of home? A few days ago, the Music Ercun Elementary School carried out a week -long "scholarship, wisdom" in the cloud theme week of cloud fun mathematics. The students of the Ercun Village Elementary Village of the Jiangxi Village, through mathematical geometric graphics creative design, combined geometric meticulous and artistic aesthetics, and strive to make mathematics experts.

Colorful mathematics, creative bell, this is the clever fusion of mathematics and art. The first grade children use the learning skills they have learned to give full play to their imagination and creativity, and make creative clocks with their favorite materials.

Many children around hot topics such as resistance and aerospace, through painting, cutting, and fighting, to present various shapes of geometric graphics or cartoon patterns. While making clocks, students can experience the close connection between mathematics and life, and also develop a good habit of cherishing time.

Qiqiao Ban is a small toy that many children like to play. The second -year children played a family interactive game of "playing to the Qiqiao Board" with their parents. According to the shape of the Qiqiao Board, 12 pieces of free combinations to see who designed the pattern fun and creative.

Children are small, great wisdom, actively start their brains, spark their minds, and designed wonderful works such as the bottom of the sea and the expectations of spring. Through parent -child activities, the children not only consolidated and met various geometric figures, realized the division and synthesis of the graphics, but also promoted the relationship between parent -child.

"Based on the formula of the area of ​​rectangular and square, and the derivative process, students, what methods can you think of the combination of 12cm²? Draw a picture on the square paper!" On the teacher's guidance Below, the third -year friends are actively thinking, some directly take 12 "whole", and some use the "cut, supplement, and move" method to create the "non -complete" graphics into a design -rich pattern.

Students first draw drafts according to their own design themes, and then modify coloring with the teacher's suggestion, improve the carving, and finally present a clear theme work. Little designers have developed multi -directional thinking in the "Interesting 12 -square -centimeter" activity and improved their ability to learn.

The use of circle in life can be seen everywhere. With the help of the round rules and ruler, the fourth grades of children in the fourth grade are rubbing their palms one by one, eager to try, combined with the theme of resistance, and use the "painting circle" and other drawing skills. It is an exquisite work of a 12 cm round pattern. Through the ruler, the students pioneered their minds, cultivated geometric intuition, enhanced their aesthetic trends, and developed practical ability.

"Hand -made three -dimensional model" is an integrated interesting thinking activity in mathematics and fusion of geometric knowledge, labor skills, art, science and other disciplines. The fifth grade children start with the development of the cube, trying to make a cube with a volume of 1 cubic centimeter, and then from the experience of making squares to the common three -dimensional graphics such as cylindrical, tritenial, and cone.

After accumulating some experience in making three -dimensional graphics, the small designers make full use of the materials in life, such as the antigen kit, oral liquid bottle, etc., to make ingenious design, and at the same time exert creativity and actively try to achieve the plane to three -dimensional to three -dimensional. In the conversion, the volume of 12 cubic centimeters of three -dimensional model is made. With the help of three -dimensional models, students fully understand the structural characteristics of the geometry, develop the concept of space, and enhance their innovation ability.

This cloud fun mathematics Weekly provides a stage for the students of Jiang Ercun Elementary School. Through a series of activities, the classroom is extended to the outside of the class, guiding students to explore the mystery of mathematics more proactively in their lives, and set off a math to play mathematics. , Learn mathematics, use mathematics boom.

"Happiness and meaningful mathematics week has come to an end. Students experience mathematical value in the activity, develop the concept of space, enhance the quality of thinking, cultivate the beauty of mathematics, and feel the beauty of mathematics. They also hope that in the future study life, they can continue to use it to use Observe the world in the eyes of mathematics, think about the world with mathematics thinking, and express the world in the language of mathematics. "The relevant person in charge of Jiang Ercun Primary School said.
