1, the pattern and mathematical elements of the national flag
The national flags of many countries have hidden mathematical elements. For example, the French national flag consists of three vertical stripes, representing freedom, equality and fraternity respectively. The Dutch national flag is composed of red, white and blue, and the ratio of these three colors is exactly 3: 3: 2.
These proportions and color distribution all reflect the mathematical considerations in the design of the national flag. You can describe these stories in handwritten newspapers and use graphics and colors to show these mathematical elements.
2. Proportion and symmetry in the national flag
The national flags of many countries show symmetry or adopt a certain proportion in some way. For example, the American flag has 13 stripes and 7 stars, which form an accurate isosceles right triangle. You can describe these proportions and symmetry, and even show how they are reflected in the national flag by graphics.
3. Symbolic meaning and mathematics of the national flag.
The national flags of many countries have their special symbolic significance, which is also related to mathematics. For example, there are maple leaves on Canada's national flag, and the number of maple leaves is 13, which represents the early 13 provinces in Canada. You can also describe these symbols and explain their relationship with mathematics.
The advantages of writing handwritten newspaper:
1, improve the ability of knowledge integration
Writing handwritten newspapers requires students to collect, sort out and screen a lot of information. In this process, they need to classify, summarize and summarize this information, which can exercise their information processing ability and improve their ability to understand and integrate knowledge.
2. Exercise the ability of autonomous learning
The writing process of handwritten newspaper is an active learning process. Students need to find and select information spontaneously, dig deep into information, and even take the initiative to consult others or consult professional books to enrich their handwritten newspapers. This process can cultivate students' autonomous learning ability.
3. Cultivate innovative thinking and critical thinking.
Writing handwritten newspapers requires students to use innovative thinking and not stick to the traditional writing mode. At the same time, they also need to think critically and evaluate the collected information to determine which information is the most relevant and accurate. This process can cultivate students' innovative thinking and critical thinking ability.
