As one of the best mathematical software in the world, the geometer's ketchpad is a program, which can provide enough means to help users realize their mathematical ideas. Operators only need to be familiar with the simple skills of using software and design and write application examples themselves. Examples reflect not the author's technical level of computer software, but teaching ideas.

As seventh-grade students, the age of 12 or 13 makes them have a natural and strong thirst for knowledge, especially for cutting-edge computer operations, which I believe every student will be very interested in. In addition, learning the operation of geometry sketchpad software is very helpful for students to abstract graphics from reality and develop the concept of space.

Therefore, the design of this activity content is particularly important, because it not only meets the needs of the times, but also enables students to feel the geometric branch of mathematics and understand the various transformations of graphics through activities, which can not only improve their spatial imagination ability, but also exercise their practical ability.

In practice, how to design creative works, express students' thoughts and feelings, and cultivate students' research-based learning ability and cooperative spirit is worthy of our teachers' thinking and active attempt.

Through the study of this course, the necessary basic knowledge and skills of information technology mathematics are obtained. Through the study of this course, we can change the traditional learning mode, use the geometry sketchpad to carry out inquiry mathematics learning, experience the mathematical ideas and methods contained in this course, feel the beauty of mathematics, and improve personal mathematical literacy.

Guide students to learn the basic wood operation of geometric sketchpad and understand the basic wood transformation such as translation, reflection and scaling of geometric figures. Under the guidance of teachers, we can use geometry to create beautiful pattern works composed of line segments, cultivate students' exploration spirit and innovative consciousness, and feel the beauty of mathematics at the same time.
