Understanding Fraction Subtraction
When fractions have the same denominator (bottom number), subtracting them is like taking steps backwards on a number line!
Imagine you have a chocolate bar divided into equal parts. If you eat some pieces, you're subtracting fractions! Number lines help us see exactly how much is left.
How to Subtract Fractions on a Number Line
1️⃣ Draw a number line divided into equal parts based on the denominator
2️⃣ Mark your starting fraction on the number line
3️⃣ Hop backwards the number of parts you're subtracting
Let's Practice Together!
Example 1: \(\frac{5}{8} - \frac{2}{8}\)
Example 2: \(\frac{7}{6} - \frac{4}{6}\)
Parent Tips 🌟
- Use real-world examples: Cut a pizza or a sandwich into equal parts to demonstrate fraction subtraction visually.
- Make it active: Have your child hop along a number line drawn with chalk to physically experience fraction subtraction.
- Connect to whole numbers: Remind them that subtracting fractions with like denominators works just like subtracting whole numbers (5 apples - 2 apples = 3 apples).
