📏 Representing Fractions on a Coordinate Ray (Number Line)

What is a Coordinate Ray?

A coordinate ray (also called a number line) is a special ray that helps us visualize and locate numbers.

Key Features:
  • 1 Origin (Начало): Starting point marked as 0
  • 2 Direction: Arrow pointing right shows numbers increase
  • 3 Unit Segment: Equal distance from 0 to 1
  • 4 Equal Divisions: Segments of equal length marked along it
Interactive visualization — available in the full lesson
💡 Remember: On a number line, numbers get larger as you move right and smaller as you move left.
