Abacus Deluxe is a simulation of a real Chinese abacus with many special additional features. The abacus is one of the first machines used for calculating. With this abacus students can learn to count and do basic arithmetic in a fun interactive way. Abacus Deluxe is a great tool for teaching place value concepts to elementary students. A typical abacus is made from a wooden frame, with either bamboo or metal rods, and wooden or ceramic beads. People who master the abacus spend a great deal of time practicing the use of the device. With Abacus Deluxe students can practice math in a fun and interactive way and just like an abacus master become faster with mental math than a person using an electronic calculator. In China and other parts of Asia the abacus is still used widely to count and calculate. We designed our abacus to be a fun way to learn counting, place value and calculating both small and large numbers.
