Understanding Fractions on a Number Line
Fractions are parts of a whole, and number lines help us see exactly how big
each part is!
When fractions have the same denominator (the bottom number), it means they're divided into the same
size pieces. Adding them is like jumping forward on the number line - each jump is one piece of the
whole!
How to Add Fractions with Like Denominators
1️⃣ Find your starting point - Begin at your first fraction on the number line
2️⃣ Make your jumps - Move forward by the amount of the second fraction
3️⃣ Land on your answer - Where you stop is the sum of the two fractions!
Let's Practice Together!
Example 1: \(\frac{1}{4} + \frac{2}{4} = ?\)
Click the fractions to see them on the number line:
\(\frac{1}{4}\)
+
\(\frac{2}{4}\)
=
?
Example 2: \(\frac{3}{5} + \frac{1}{5} = ?\)
Drag the slider to see how the fractions add up:
\(\frac{3}{5} + \frac{0}{5} = \frac{3}{5}\)
Parent Tips 🌟
- Use real-world examples: Cut a pizza or a chocolate bar into equal parts to show how fractions add up visually.
- Make it physical: Have your child hop along a number line drawn with chalk outside to physically experience adding fractions.
- Start simple: Begin with fractions that add up to 1 whole (like 1/4 + 3/4) before moving to sums greater than 1.
