What Does It Mean to Balance Equations?
Balancing subtraction equations means making sure both sides of the equals sign (=) have the same value.
Just like a seesaw needs equal weight on both sides to stay balanced, math equations need equal values on both sides of the equals sign!
How to Balance Subtraction Equations
1️⃣ Look at both sides of the equation
2️⃣ Calculate the side that's complete
3️⃣ Find the missing number that makes both sides equal
Let's Practice Balancing!
Example 1: Find the missing number
12 - 5 = ? - 2
7
9
5
Example 2: Which equation is balanced?
Option A: 15 - 6 = 10 - 1
Option B: 18 - 9 = 7 - 0
A
B
Both
Parent Tips 🌟
- Use real objects: Try balancing actual objects (like toys or blocks) on a homemade scale to demonstrate the concept visually.
- Make it a game: Create "equation races" where your child competes against the clock to balance equations correctly.
- Relate to daily life: Point out balancing situations in everyday life, like sharing equal amounts of snacks between siblings.
