Understanding Decimal Numbers on a Line
Number lines help us see exactly where decimal numbers belong!
Just like whole numbers, decimals can be placed on a number line. The further to the right a number is, the larger it is. Let's learn how to compare decimals like 0.4 and 0.35 by seeing where they fall on the number line.
How to Compare Decimals on Number Lines
1️⃣ Draw a number line with appropriate decimal markings
2️⃣ Plot the decimal numbers you want to compare
3️⃣ Compare their positions - the number to the right is larger!
Let's Practice Together!
Example 1: Compare 0.7 and 0.65
0.6
0.65
0.7
0.75
0.8
0.85
Which is larger? Look at their positions!
Example 2: Drag the Points to Compare
Drag the red points to these decimals: 1.25 and 1.3. Which is larger?
1.2
1.22
1.24
1.26
1.28
1.3
Drag both points to see which is larger!
Parent Tips 🌟
- Use real-world examples: Show decimal comparisons with money ($1.25 vs $1.30) or measurements (1.5 liters vs 1.75 liters) to make it practical.
- Make your own number lines: Create number lines on paper or with string and clothespins for hands-on learning.
- Play decimal games: Try "Decimal War" with playing cards (use face cards as decimal points) to practice quick comparisons.
