Understanding Fractions on Number Lines
Fractions are parts of a whole!
When fractions have the same denominator (the bottom number), it means they're divided into the same number of equal parts. Number lines help us see exactly where fractions are and how to add or subtract them by making hops.
How to Add and Subtract Fractions with Like Denominators
1️⃣ Draw a number line divided into equal parts based on the denominator
2️⃣ Mark your starting fraction on the number line
3️⃣ Hop forward to add or backward to subtract fractions
Let's Practice Together!
Example 1: Adding Fractions
Let's add \(\frac{2}{5} + \frac{1}{5}\) using a number line:
\(\frac{1}{5}\)
\(\frac{1}{5}\)
\(\frac{1}{5}\)
Current total: \(\frac{2}{5}\)
Example 2: Subtracting Fractions
Let's solve \(\frac{4}{6} - \frac{2}{6}\) using a number line:
Current total: \(\frac{4}{6}\)
Parent Tips 🌟
- Use real-world examples: Cut a pizza or a chocolate bar to show how fractions with the same denominator work.
- Make it physical: Have your child hop along a number line drawn with chalk on the sidewalk to physically experience adding and subtracting fractions.
- Practice with games: Create fraction cards and have your child move game pieces along a homemade number line board game.
