🧠 Let's Solve Missing Number Problems! 🧠
Missing number problems are like math puzzles where we need to find the hidden number!
🔍 Step-by-Step Process:
- Step 1: Look at the equation and identify what operation is being used (+, -, ×, ÷)
- Step 2: Figure out which number is missing
- Step 3: Use the opposite operation to find the missing number
- Step 4: Check your answer by putting it back in the original equation
Example 1: Addition - 5 + _ = 12
+
?
=
5 red dots + 7 = 12 blue dots!
Process: 12 - 5 = 7
Example 2: Subtraction - _ - 4 = 9
?
-
=
13 - 4 green dots = 9 purple dots!
Process: 9 + 4 = 13
Example 3: Multiplication - 4 × _ = 20
×
?
=
4 orange dots × 5 = 20 pink dots!
Process: 20 ÷ 4 = 5
Example 4: Division - _ ÷ 3 = 6
?
÷
=
18 ÷ 3 teal dots = 6 brown dots!
Process: 6 × 3 = 18
✨ Key Rule: Use the opposite operation!
- Addition ↔ Subtraction
- Multiplication ↔ Division
🎯 Practice Problems:
- 3 + _ = 10 (Answer: 7)
- _ + 6 = 14 (Answer: 8)
- 15 - _ = 8 (Answer: 7)
- 6 × _ = 36 (Answer: 6)
- _ ÷ 4 = 5 (Answer: 20)
