What Is the Number Line Ruler Used For?
A number line makes integer rules visible. Adding a positive number moves one way along the line and subtracting moves the other, so a student can check a sum such as -7 + 12 by counting along the ruler before working it out mentally. Because zero sits well inside the range from -50 to 100, negative and positive values appear on one continuous scale. The vertical line reads like a thermometer; the horizontal one matches the number line in most textbooks.
Integers are introduced in CBSE class 6 and operations with integers continue in class 7, so the ruler fits middle-school maths lessons and integer activities in a school maths lab.
