School Abacus
Around the world, abaci have been used in pre-schools and elementary schools as an aid in teaching the numeral system and arithmetic.
In Western countries, a bead frame similar to the Russian abacus but with straight wires and a vertical frame has been common (see image). It is still often seen as a plastic or wooden toy.
The type of abacus shown here is often used to represent numbers without the use of place value. Each bead and each wire has the same value and used in this way it can represent numbers up to 100.

Famous quotes containing the word school:
“... the school should be an appendage of the family state, and modeled on its primary principle, which is, to train the ignorant and weak by self-sacrificing labor and love; and to bestow the most on the weakest, the most undeveloped, and the most sinful.”
—Catherine E. Beecher (1800–1878)
