Free Grade 4 worksheets: Multiply by 10, 100, 1,000 using patterns

🔢 Topic Summary

Multiplying by 10, 100, and 1,000 is easier than you think because it follows a simple pattern. When you multiply a number by 10, you simply add one zero to the end of the number. Multiplying by 100 means adding two zeros, and multiplying by 1,000 means adding three zeros. Understanding this pattern makes mental math a breeze!
