# Negative Number Lines from Minus 20

## What is the resource?

This PDF provides number lines extending to both sides of zero. It's designed for learners (upper primary to early secondary) starting to grasp negative numbers.

## Why are negative numbers important?

They model real-world situations most basic numbers won't cover:

- Temperatures: Below zero on a thermometer is a daily experience for students in some climates.
- Money: Debts, budgets, and going 'in the red' all use negative values to make sense.
- Science: Readings may dip below zero on instruments – understanding scales is essential.
- Elevation: 'Below sea level' isn't possible to show numerically without negatives.

## Why is this resource helpful?

Number lines make this tricky concept more visual and easier to grasp:

- Zero's meaning: It becomes a 'centre', negative numbers the mirror image across it.
- Adding & subtracting: 'Hops' now go right OR left, revealing the rules of negatives clearly.
- Less memorization: Seeing patterns means better understanding and less focus on tricks.
- Printable PDF: Teachers can give every student the tool for practice & visualisation.

Negative numbers open up advanced maths. These number lines build intuition about how operations with both positive and negative numbers work.
