Counting Devices

Counting Devices

Abacus

• A manual counting device used for basic arithmetic operations
• Consists of a frame with wires and beads
• Beads are moved to represent numbers and perform calculations
• Used for thousands of years in various cultures
• Still used today in some parts of the world, especially in Asia

Number Lines

• A visual representation of numbers on a line
• Used to display relationships between numbers and perform basic arithmetic operations
• Can be used to demonstrate concepts such as:
  • Addition and subtraction
  • Comparison of numbers (greater than, less than, equal to)
  • Patterns and sequences
• Can be adapted for different age groups and skill levels

Calculators

• Electronic devices that perform mathematical calculations
• Can perform basic arithmetic operations (addition, subtraction, multiplication, division) and more complex calculations (exponents, roots, trigonometry)
• Types of calculators:
