1. Determine the number and method of bead pulling: the number of bead pulling is 1-9, and the method of bead pulling refers to pulling or putting down a bead in a digital position.
2. Observe the process of drawing beads and find out which numbers are used to draw beads.
3. Determine the number of times each number is used to dial the beads and record it.
4. Add up the number of times each number is used to dial the beads to get the total.
5. Use mathematical formula to express the sum.
For example, the process of dialing beads is like this: in the first line, dial 2 for 3 times, dial 3 for 2 times; In the second line, dial 1 times 1, 2 times 2, 3 times 3; In the third line, you dialed 4 1 times 5. The following formula can be written: 3+2+2+1+2+3+4+1+5 = 24.
Therefore, the formula of this process is: 24.
The Origin and History of Pinzhu
The process of pulling beads can be traced back to the ancient abacus. In China BC, abacus appeared as a calculating tool and was widely used in business and mathematics for a long time. With the passage of time, the abacus gradually developed and perfected, forming a modern style. As a calculation method, bead pulling came into being and is still used today.
The Application of Balling in Mathematics
Pinching beads is widely used in mathematics. For example, when calculating basic operations such as addition, subtraction, multiplication and division, you can quickly get the result by dialing the beads. In addition, pinball can also be used to solve some complex mathematical problems, such as large number multiplication and square root operation. Through the operation of beads, complex mathematical problems can be transformed into simple mechanical operations, which greatly reduces the difficulty and complexity of calculation.
The significance of playing with pearls to children's arithmetic education
Pearl picking process is of great significance to children's arithmetic education. Through the practice of picking pearls, children can deepen their understanding of numbers and mathematical concepts, improve their hand-eye coordination ability and cultivate their interest and hobby in mathematics. In addition, pinball can also be used as a game to help children learn and master mathematics knowledge in a relaxed and happy atmosphere.
