# Rounding Significant Figures Example

## What is the resource?

This PDF demonstrates 'significant figure' rounding using worked examples. Designed for secondary learners encountering this concept in science and maths topics.

## Why is rounding to significant figures important?

It lets us express answers with appropriate precision, matching the context:

- Measurements & science: Equipment has its limits – overstating accuracy in a result is misleading.
- Huge quantities: 3 significant figures make big numbers like populations easier to compare quickly.
- Data presentation: Round appropriately so audiences grasp what matters with less mental 'clutter'.
- Further maths prep: Error & approximation techniques build on significant figures understanding.

## Why is this resource helpful?

This concept requires careful rules, this sheet breaks it down for easier practice:

- Clear steps: Shows HOW to identify which digits matter most – not just final answers.
- Common mistake focus: Zero placeholders get tricky - examples pinpoint where errors happen.
- Varied questions: Makes students apply the idea beyond the first rule example to check skill.
- Printable PDF: Allows teachers to use the same problems for whole class learning, or revise later.

It makes rounding accurate, not random! Students see this as a meaningful skill for interpreting & communicating calculated results.
