Multiplying Two Digits by One Digit
Grade 4 · Math · Multi-Digit Multiplication · Virginia, USA
Lesson Summary
Multiply a two-digit number by a one-digit number using place value. Break the bigger number into tens and ones to make it easier.
Explanation
To multiply a number like 34 × 5, you can break 34 into 30 and 4. First multiply 30 × 5 to get 150, then multiply 4 × 5 to get 20. Add those two results together: 150 + 20 = 170. This is called the partial-products method. You can also line the numbers up vertically and multiply each digit one at a time, starting from the ones place.
