Many different places use some form of the abacus, including:
Russia Egypt Rome Germany China Japan Greece United States
Different kinds of abaci include
Suan Pan (China) Soroban (Japan) Schoty (Russia) Nepohualtzitzin (Aztec civilisation) Among others
The word ‘abacus’ is said to have originated from either the Hebrew or Latin languages: ‘abaq’ is Hebrew for ‘dust’ (as calculations were
performed in the dirt or with stones) ‘abax’ is Latin for ‘table’ (derived from the Greek)
In the Asian countries, ‘soroban’ and ‘suan pan’ both mean ‘calculating board’.
*Watch Candace demonstrate using her homemade soroban
Easier for kids to learn more about: Place value Multiplication
Division Addition Subtraction
Different Cultures
Abacus is a means to represent numbers in a different manner. Kids can manipulate objects to make learning some concepts easier. Kids can learn how to do mental math easier (learn how to utilise ‘imaginary abacus’).
Awesome video showing a math class in Japan, and use of their ‘imaginary abacus’: http://www.youtube.com/watch?v=wIiDomlEjJw
