Fraction Friends: Adding and Subtracting
Fractions are like puzzle pieces that fit together!
When we add or subtract fractions, we're combining or taking away parts of a whole. Remember: we can only directly add or subtract fractions when they have the same denominator (the bottom number). If they don't, we need to find equivalent fractions with a common denominator first.
The Fraction Action Plan
1️⃣ Check the denominators - Are they the same?
2️⃣ Find a common denominator if needed (the LCM works great!)
3️⃣ Add or subtract the numerators (top numbers) and keep the denominator
4️⃣ Simplify your answer if possible
Let's Practice Together!
Example 1: Pizza Party Fractions
You have 3/8 of a pepperoni pizza and your friend gives you 2/8 more. How much pizza do you have now?
3/8 + 2/8 = (3 + 2)/8 = 5/8
You now have 5/8 of the pizza! That's more than half! 🎉
Example 2: Candy Bar Fractions
You have 7/12 of a candy bar. You eat 3/12. How much is left?
7/12 - 3/12 = (7 - 3)/12 = 4/12
We can simplify 4/12 by dividing numerator and denominator by 4: 1/3
You have 1/3 of the candy bar left! Save it for later! 🍫
Parent Tips 🌟
- Use real-world examples: Cooking measurements (cups, tablespoons) are perfect for practicing fraction operations.
- Visual aids help: Draw circles or rectangles divided into fractions to make abstract concepts concrete.
- Make it a game: Create fraction cards and have your child solve problems to earn points or small rewards.
