Abacus

ABACUS

An abacus is a simple, ancient tool used for counting and performing arithmetic operations. It consists of a series of rods or wires, each holding beads that can be moved back and forth. The beads are typically divided into groups, representing different place values (like ones, tens, hundreds). By sliding the beads, users can perform addition, subtraction, multiplication, and division. It was widely used in various cultures before the advent of modern calculators..

History

  • The abacus dates back thousands of years, with evidence of its use in ancient Mesopotamia (around 2300 BCE) and ancient China (around 500 BCE). It was also used in Greece, Rome, Egypt, and Japan.
  • The device was an essential tool for merchants, traders, and accountants to perform complex calculations before the invention of the modern calculator.

Key Principles of Abacus

Letter-Sound Correspondence

Phonics teaches that letters (or groups of letters) correspond to specific sounds. For instance, "c" can represent the /k/ sound (as in cat) or the /s/ sound (as in circle)..

Blending

Blending is the ability to combine individual sounds to form words. For example, blending the sounds /c/ /a/ /t/ creates the word cat.

Segmenting

Segmenting is the opposite of blending and involves breaking down words into their individual sounds. For example, the word "dog" can be segmented into /d/ /o/ /g/.

Digraphs

Digraphs are two letters that together make one sound. For example, "ch" in chat, "th" in this, and "sh" in ship.

Silent Letters

The Handwriting class aims to help students develop neat, legible, and consistent handwriting. Through practice and guided exercises, students will improve their fine motor skills, learn proper pencil grip, and practice letter formation. Whether it’s cursive or print writing, our program focuses on helping students develop a writing style that is both legible and efficient. Good handwriting is a crucial skill that boosts confidence in both academic and personal writing.

Uses

  • Mathematical calculations: It is used for basic arithmetic like addition, subtraction, multiplication, and division.
  • Educational tool: In many countries, the abacus is still used to teach young students basic math concepts.
  • Mental calculation: It helps people improve mental arithmetic by visualizing the process on the abacus and enhancing their calculation speed.
