1. Preparation tools: paper, pencils, erasers, markers and other painting tools. Determine the layout of the picture: divide the picture into several parts, draw a multiplication table for each part, such as 16 part which can be divided into 4 rows and 4 columns, and draw a multiplication table for each part. Draw a table: draw a table in each part with the same number of rows and columns as the multiplication table.
2. Fill in numbers: Fill in the corresponding numbers in the table, such as the number 1 in the first row and column, the number 2 in the second row and column, and so on until the whole table is filled in. Draw an arrow: draw an arrow between each table to indicate the direction of multiplication. The starting point of the arrow is the cell where the first number is located, and the ending point is the cell where the second number is located.
3. Draw an image: draw an image in each table, and the number of images is the same as the number of numbers in the multiplication table. For example, draw a bird in the first row and the first column of the table, indicating that 1 times 1 results in 1. Draw two birds in the first column of the second row of the table, indicating that the result of multiplying 2 by 1 is 2, and so on.
The origin of multiplication formula
1, multiplication formula is one of the basic contents of mathematics education in ancient China, and its origin can be traced back to the Spring and Autumn Period and the Warring States Period. At that time, the multiplication formula was mainly used to calculate multiplication operation in order to solve practical problems better. With the passage of time, multiplication formula has gradually spread all over Asia and become one of the basic contents of mathematics education in Asian countries.
2. The multiplication formula was originally compiled by mathematicians in the Spring and Autumn Period and the Warring States Period for the convenience of calculation. Mathematicians at that time had mastered some basic mathematical concepts and operation methods, such as addition, subtraction, multiplication and division, but there were still some difficulties in the practical application of multiplication.
In order to solve this problem, mathematicians began to study the multiplication formula. They found that the product can be calculated quickly by compiling some simple formulas. These formulas are usually written in the form of rhythm, which is more convenient for people to remember and master. The multiplication formula plays a very important role in the ancient mathematics education in China.
