High Quality Content by WIKIPEDIA articles! Sand table is a somewhat generic name for using constrained sand for modeling or educational purposes. The original version of a sand table seems to be the abax used by early Greek students. An abax was a table covered with sand commonly used by students, particularly in Greece, to perform studies such as writing, geometry, and calculations. An abax was the predecessor to the abacus. Objects, such as stones, were added for counting and then columns for place valued arithmetic. The demarcation between an abax and an abacus seems to be poorly defined in history, moreover, modern definitions of the word "abacus" universally describe it as a frame with rods and beads and, in general, do not include the definition of "sand table".
