Multi-Digit Multiplication (Standard Algorithm) — Easy Worksheet 1
Grade 5 · Whoobee Name: ____________________ Date: __________
Answer each question. The same kind of multiplication comes in different shapes. Use the standard algorithm and show your partial products.
How to solve
Multiply the top number by the ones digit of the bottom number, then by the tens digit (write a 0 in the ones place first), then by the hundreds digit (write two zeros). Add the partial products to get the answer.
Example
Find the product.
Answer: 828
Warm-up
Not quite. The answer is
💡 Ones: 8 × 5 = 40. Write 0 and carry 4. Tens: 1 × 5 = 5, plus the carried 4 is 9. Write 9. Hundreds: 5 × 5 = 25. Write 25. So 518 × 5 = 2,590.
✓ Correct!
