Dear friends, please note:
This product is very cost-effective, as the beads are manually sorted by hand. There might be some small cracks or small gaps in some beads, but they do not affect normal use. Such issues are not grounds for exchanges or returns. If you are concerned, please do not purchase!!!
This is a very practical teaching aid for the family. Babies can recognize individual, ten, hundred, thousand, and ten thousand, making it an ideal teaching aid for parents to initiate their children's education..Abacus is also a simple and convenient calculation tool invented by the Han ethnic group. Due to the convenience and speed of abacus operations, it has been widely used as a calculation tool for thousands of years among the Han people, and even the most advanced electronic calculators cannot completely replace the role of the abacus.
In layman's terms, mental arithmetic is essentially doing mental calculations. Based on the practice of arithmetic, mental arithmetic involves fully internalizing the arithmetic process, thereby completely eliminating the external actions of actual arithmetic. This internalized "mental abacus" (also known as the "virtual abacus") allows calculations such as addition, subtraction, multiplication, and division to be performed in the mind. Mental arithmetic is characterized by group calculations, which can be particularly challenging for young children to master large numbers. This method helps them better understand the concept of numbers and overcome the tendency to count individually. The "five-step, ten-step system" of mental arithmetic significantly reduces the difficulty of carrying. The operational model of mental arithmetic is also conducive to improving children's computational abilities.
