Step-by-Step Guide to Multiplying 1-Digit by 3-Digit Numbers
FAQs on Multiply 1-Digit by 3-Digit Numbers in Columns: Grade 4 Worksheet
1. How do you multiply a 3-digit number by a 1-digit number using the column method?
To multiply a 3-digit number by a 1-digit number using the column method, you multiply in stages from right to left, focusing on place value. This method is a core part of the Class 4 maths curriculum.
Here are the steps:
- Step 1: Write the 3-digit number on top and the 1-digit number below it, aligning them by place value (ones under ones).
- Step 2: Multiply the 1-digit number by the ones digit of the top number. Write the result below.
- Step 3: Multiply the 1-digit number by the tens digit. Add any 'carry over' from the previous step.
- Step 4: Finally, multiply the 1-digit number by the hundreds digit and add any carry-over to get the final answer.
2. What grade level is 3-digit by 1-digit multiplication typically taught?
Multiplication of a 3-digit number by a 1-digit number is a fundamental topic typically introduced and mastered in Grade 4. This worksheet is specifically designed for Class 4 students to practice and build confidence in this skill, aligning with the CBSE and NCERT curriculum.
3. Is this Class 4 multiplication worksheet available as a free printable PDF?
Yes, this multiplication worksheet for Class 4 is available as a free, downloadable PDF. It is designed to be easily printable, making it perfect for parents and teachers who need a quick resource for homework, holiday practice, or in-class exercises.
4. Does this practice worksheet include an answer key for checking?
Yes, this worksheet comes with a complete answer key. Including the multiplication 3-digit by 1-digit with answers allows for quick and easy checking, enabling students to self-correct and parents to assist effectively without needing to solve every problem themselves.
5. How does column multiplication help in understanding maths concepts?
The column multiplication method is crucial for reinforcing a student's understanding of core mathematical concepts. It visually demonstrates the importance of place value (ones, tens, hundreds) and introduces the process of regrouping or carry-over, which is essential for more complex arithmetic like long multiplication.
6. What is 'regrouping' or 'carry over' in multiplication?
In column multiplication, regrouping (or carry over) is what you do when the result of multiplying a column is a two-digit number. For example, if you multiply 6 by 8 and get 48, you write down the 8 in the ones column and 'carry over' the 4 to the top of the next column (the tens place) to be added in the next step. This worksheet includes problems with multiplication with regrouping to help students master this skill.
7. How can I use this worksheet for my child's exam preparation?

10. How do I multiply in columns step-by-step?
Here is a simple step-by-step guide to mastering the column multiplication method for a 1-digit by 3-digit problem:
- Set Up: Write the 3-digit number above the 1-digit number, carefully lining up the ones, tens, and hundreds columns.
- Multiply the Ones: Multiply the bottom digit by the digit in the ones place of the top number. Write the answer below.
- Multiply the Tens: Multiply the bottom digit by the digit in the tens place. Add any number you carried over from the last step.
- Multiply the Hundreds: Repeat the process for the hundreds place, again adding any carry-over to find the final product.
