1. Use video websites: Visit video websites such as YouTube, Youku and iQiyi, which provide powerful search functions. Enter keywords in the search box of the website, such as the title, actors and directors of the video, and then click the search button to get relevant video results.

2. Use search engines: Use search engines such as Google and Baidu to enter video-related keywords, and search engines will return video links and web pages related to keywords. You can click on the link to view and watch the video.

3. Use mobile applications: Many video playback applications, such as YouTube, Tencent Video, and Beep Beep. , providing search function. You can enter keywords in these applications to search for videos and select videos of interest to watch.

All major education websites have detailed and diverse detailed teaching videos for reference. Counting method is a mathematical method of counting with small dots, which can help first-year students better understand and learn mathematical concepts. Prepare a piece of paper and a pen. Draw a square on the paper, and each small square can be used to put a point, so that it can be counted by the point method.

Suppose you need to calculate the number 4, you can draw four points on the paper, let the children see these four points and help them understand that these four points represent the number 4. Similarly, if you want to calculate the number 8, draw eight points, and so on.

In addition to basic counting, point method can also be used in the teaching of addition and subtraction. For example, if you calculate 2+3=5, you can draw two points and three points on the paper, and then add up these points to get five points, so that children can understand the concept that 2+3 equals 5.

The point method can also be used to compare sizes. For example, two groups of points can be drawn on paper, and then children can compare which groups of points are more or less, thus helping to understand the relationship between size in mathematics. The point method can also be extended to higher-level mathematical concepts, such as the teaching of decimals and fractions. In teaching, dots of different sizes can be used to help children better understand these digital concepts.

Point method is a simple and effective mathematical counting method, which is suitable for mathematics teaching of first-year students. By using the method of points, children can understand and master mathematical concepts more easily, and can further expand to a higher level of mathematical content on this basis.

Application of point method

1, the dot method can count not only dots, but also symbols of other shapes and colors. For example, when calculating 2+3, you can use two red dots and three blue dots to represent these numbers. In this way, children can understand the process of addition more intuitively.

2. The dot matrix method can also be used in the teaching of geometry and statistics. Geometrically, we can teach the concepts of area and perimeter of graphics by point method; In statistics, you can use the point method to make a frequency table or histogram.

3. Pointing method is a multifunctional teaching tool for mathematics, which can help children better understand and master mathematical concepts. When using the point method, we should pay attention to clear explanation and practical application to help children learn mathematics better.
