Geometry Sketchpad is a tool software suitable for mathematics teachers and students to teach and learn mathematics. It has dynamic graphics function, rich transformation function, powerful animation function, convenient function image function and simple operation. Applying the Geometer's Sketchpad to the "Inquiry Learning" in the mathematics classroom will make students willing and really have the opportunity to explore independently, instead of being dragged by the teacher to get the result of the problem directly.

1. Embody the beauty of mathematics with the help of the geometric sketchpad and stimulate students' interest in learning mathematics.

In the past, in order to make students feel the beauty of mathematics, teachers spent a lot of energy and physical strength to collect information, draw pictures and even color on the blackboard endlessly. Nowadays, by using the dynamic jigsaw puzzle of the geometric sketchpad, we can draw beautiful pythagorean trees, combinations of rotating and transforming squares and a series of figures that can reflect the beautiful side of mathematics.

2. With the help of the geometric sketchpad, abstract mathematical concepts can be visualized.

Concepts in mathematics are often abstract and difficult for students to understand, which is a difficult point in mathematics teaching. If we can apply the geometry sketchpad teaching, we can visualize some concepts, make the knowledge simple and clear, and make it easier for students to accept. For example, when learning the concept of "axis symmetry", using the geometric sketchpad to demonstrate can not only attract students' attention, but also master the learning knowledge.

3. With the help of the geometry sketchpad, explore the essence and theorem of mathematics, and change learning mathematics into doing mathematics.

Geometric sketchpad can help students observe, explore and discover the quantitative relationship and spatial structure relationship between objects dynamically, so it can be used as an effective tool for mathematical experiments. In the teaching of theorems, formulas and laws, the Geometer's Sketchpad provides measuring and calculating functions, which can measure the manufactured objects and calculate the measured values.

4. Visualize function images and attributes with the help of the geometric sketchpad.

The image and nature of function is the key and difficult point of middle school mathematics. It is very helpful for students to make full use of geometry sketchpad to concretize and visualize abstract content in teaching.

5. With the help of the geometric sketchpad, complicated methods such as the combination of numbers and shapes are simplified.

In actual teaching, our teachers need to provide some simple and intuitive vivid demonstrations, so that students can experience math problems personally, and students can really understand relevant knowledge, and the Geometry Sketchpad just provides such a scene for our math teaching.
