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:
“Sure, you can love your child when he or she has just brought home a report card with straight “A’s.” It’s a lot harder, though, to show the same love when teachers call you from school to tell you that your child hasn’t handed in any homework since the beginning of the term.”
