Understanding Multiplication Patterns
Did you know multiplication follows beautiful patterns when we change place values?
When we multiply numbers by 10, 100, or 1000, we're not just making numbers bigger - we're seeing a special pattern that helps us solve problems faster!
How Place Value Affects Multiplication
1️⃣ Each zero in the multiplier moves the decimal point one place to the right
2️⃣ The digits stay the same, just their place value changes
3️⃣ Patterns repeat whether multiplying by 10, 100, or 1000
Let's Explore Some Examples!
Example 1: The Magic of 10s
What happens when we multiply 4.3 by different powers of 10?
4.3 × 10 = Click to reveal
4.3 × 100 = Click to reveal
4.3 × 1,000 = Click to reveal
Do you see how the decimal point moves to the right each time?
Example 2: Pattern Detective
Let's investigate this pattern with a bigger number!
Complete this table by multiplying 25.6:
| Multiplier | Product |
|---|---|
| × 10 | Click |
| × 100 | Click |
