Understanding Decimal Comparison
Number lines make comparing decimals super easy!
When we place decimals on a number line, the number that appears further to the right is always greater.
This visual method helps us understand decimal values better than just looking at the digits.
How to Compare Decimals on a Number Line
1️⃣ Identify the range - Look at the whole numbers at each end
2️⃣ Find the decimal points - Locate where each decimal falls on the line
3️⃣ Compare positions - The number further to the right is greater!

Parent Tips 🌟
- Use real-world examples: Show how decimals appear in money, measurements, or sports statistics to make the concept more concrete.
- Create your own number lines: Use string and paper clips to make physical number lines that kids can manipulate.
- Play decimal games: Try "Decimal War" with playing cards where each card represents a decimal place (e.g., 3♦ 5♥ becomes 3.5).
