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 \(\frac{3}{8}\) of a pepperoni pizza and your friend gives you \(\frac{2}{8}\) more. How much pizza do you have now?
\(\frac{3}{8} + \frac{2}{8} = \frac{(3 + 2)}{8} = \frac{5}{8}\)
You now have \(\frac{5}{8}\) of the pizza! That's more than half! 🎉
Example 2: Candy Bar Fractions
You have \(\frac{7}{12}\) of a candy bar. You eat \(\frac{3}{12}\). How much is left?
\(\frac{7}{12} - \frac{3}{12} = \frac{(7 - 3)}{12} = \frac{4}{12}\)
We can simplify \(\frac{4}{12}\) by dividing numerator and denominator by 4: \(\frac{1}{3}\)
You have \(\frac{1}{3}\) 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.
