The earliest mathematical work in China was Zhoubi Suanjing, which was written by Zhou Bi during the Tang Dynasty (712 - 770 AD). This book contained some early mathematical knowledge such as fraction, decimals, percentage, geometric figures, etc. It was one of the important landmarks in the development of ancient Chinese mathematics. Zhoubi Suanjing was also one of the most important documents in the history of ancient Chinese mathematics. It was considered one of the earliest mathematical works in China.

The earliest mathematics book in China was Zhoubi Suanjing, which was written around the 13th century B.C. It was one of the important landmarks in the history of Chinese mathematics. " Zhoubi Suanjing " was a comprehensive mathematical work that mainly focused on arithmetic. It mainly introduced the mathematical knowledge and algorithms of the Zhou Dynasty, including arithmetic, algebra, geometry, trigonometrification, calculus, and many other aspects. It was an important starting point for the development of ancient Chinese mathematics and had a profound impact on the development of mathematics in later generations.

#Title: " Elementary Mathematics Lower Grade Speed Calculation Competition: A Wonderful Duel of Wisdom and Speed " In the vast world of primary school mathematics education, the speed calculation competition was like a bright star, shining with a unique light. Speed calculation, as the cornerstone of mathematics learning, showed its importance in the lower grades. It was not only a direct test of the students 'computational ability, but also a comprehensive challenge to their mental agility and concentration. Look, in the Yanghe Experimental School's speed calculation competition, the first-year contestants embarked on this journey full of challenges and opportunities. The tense atmosphere of the preliminary round permeated the air. They needed to solve 50 questions in just three minutes. This was undoubtedly a contest of speed and accuracy. Every number was a small challenge, and every calculation was a step towards victory. After a fierce competition, the elite contestants of each class stood out and represented their class in the finals in the afternoon. In the finals, the young contestants were all fully focused. They sat upright and held their pens accurately. Their serious appearance seemed to be conducting an incomparably sacred academic research. They wrote neatly and quickly, showing their solid basic skills and strong psychological quality. The oral arithmetic competition of Yucai Primary School in Liquan County was equally brilliant. The competition was a written test with a time limit of 15 minutes to complete 50 questions. Before the match, Vice-Principal Wang Juan's encouragement was like a spring breeze, injecting full motivation into the students. At the start of the game, the young players were full of fighting spirit. Some of them were frowning and thinking seriously, some were writing confidently, and some were counting their fingers, looking very cute. After the competition, the students who won the titles of " Little Expert in Mental Arithmetic " and " Divine Mathematical Arithmetic " had proud smiles on their faces. This was the reward for their hard work. There was also the Dugang Elementary School's speed calculation competition. Before the competition, the mathematics teaching and research team carefully set the questions. On the basis of considering the calculation level of the first to second grade students, they cleverly designed the questions. It was not only an examination of basic knowledge, but also a challenge to the sensitivity of thinking. On the field, the students buried their heads in their pens and began a fierce speed competition. This competition was like a feast of knowledge and wisdom. Every student was a participant and an explorer. These speed calculation competitions were not just simple competitions, but also an all-round improvement of the students 'mathematical attainment. Through the competition, the children's heart, brain, and hand coordination skills were trained, and their mental and pen arithmetic skills were also significantly improved. At the same time, these competitions also greatly stimulated students 'interest in mathematics, allowing them to swim in the ocean of mathematics and feel the charm of mathematics. The teachers could also understand the overall level of the students through the competition and then adjust their teaching strategies to better develop the students 'mathematical ability. The speed calculation competition was like a magical key that opened the door to the mathematics wisdom of the lower grade students and led them further and further on the road of mathematics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many ways to design the primary school mathematics competition. For example, individual and team competitions could be set up. The individual competition would have a compulsory answer segment, and the team competition would have a compulsory answer segment. Each school's representative team could have a certain number of opportunities (such as two) to ask for help outside the field. The competition covered in-class knowledge such as calculations, graphics, and geometry. At the same time, it set up puzzle questions such as 24-point and Sudoku. He could also set up a computational ability test segment, including mental arithmetic, vertical calculation, off-line calculation, solving equations, etc. He could also set up a thinking question segment to test the students 'thinking ability. In addition, the Teacher Quality Competition could be composed of segment teaching, blackboard design, chalk writing, talent performance, and other parts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
