Understanding 2-digit Multiplication
Multiplying by 2-digit numbers might seem tricky at first, but once you learn the steps, you'll be solving these problems like a pro!
When we multiply by 2-digit numbers, we're really just doing simple multiplication several times and adding the results together. It's like building with blocks - we work with one piece at a time until we create the whole picture.
The Step-by-Step Method
Let's Practice Together!
Example 1: 24 × 13
Click to see the step-by-step solution!
Step 1: Multiply 24 by 3 (the ones digit) → 24 × 3 = 72
Step 2: Write a zero placeholder →
Step 3: Multiply 24 by 1 (the tens digit) → 24 × 10 = 240
Step 4: Add them together → 72 + 240 = 312
Answer: 312
Example 2: 37 × 45
Click to reveal how to solve this!
Step 1: Multiply 37 by 5 → 37 × 5 = 185
Step 2: Write a zero placeholder →
Step 3: Multiply 37 by 4 → 37 × 40 = 1,480
Step 4: Add them together → 185 + 1,480 = 1,665
Answer: 1,665
Parent Tips 🌟
- Real-world practice: Have your child calculate totals when shopping (e.g., 12 apples at $0.35 each) to make multiplication meaningful.
- Break it down: Encourage drawing a grid or using graph paper to keep numbers neatly aligned during calculations.
- Celebrate small wins: Mastering 2-digit multiplication takes time - praise effort and correct steps even if the final answer isn't perfect.
