What Are Variable Equations?
Equations are like math puzzles where we need to find missing numbers!
A variable is a letter (like x) that stands for an unknown number. Solving equations means finding what number the variable represents to make the equation true.
How to Solve Simple Equations
1️⃣ Identify the variable (the letter in the equation)
2️⃣ Balance both sides (like a seesaw that needs to be even)
3️⃣ Solve step by step to find the missing number
Let's Practice Together!
Example 1: The Cookie Mystery
Sam has some cookies. After eating 3 cookies, he has 7 left. How many cookies did he start with?
To solve x - 3 = 7:
1. Add 3 to both sides to keep it balanced
2. x - 3 + 3 = 7 + 3
3. x = 10
Example 2: Sharing Pencils
Emma wants to share her pencils equally with 3 friends. If each person gets 5 pencils, how many pencils does Emma have?
To solve x ÷ 4 = 5:
1. Multiply both sides by 4 to keep it balanced
2. x ÷ 4 × 4 = 5 × 4
3. x = 20
Emma has 20 pencils! ✏️✏️✏️✏️
Parent Tips 🌟
- Use real objects like blocks or coins to physically demonstrate balancing equations
- Make it a game - create "equation stories" where your child plays detective to find the missing number
- Celebrate mistakes - show how wrong answers help us learn by adjusting the balance
