How to Solve 3-Digit by 1-Digit Multiplication with Regrouping
FAQs on Multiply 1 Digit by 3 Digit Numbers: Class 4 Maths Practice Worksheet
1. How to multiply 1 digit by 3 digits?
To multiply a 3-digit number by a 1-digit number, you use the column multiplication method, multiplying the single digit with each digit of the three-digit number from right to left (ones, tens, and hundreds).
- Step 1 (Multiply the Ones): Multiply the single-digit number by the digit in the ones place of the 3-digit number. Write down the result.
- Step 2 (Multiply the Tens): Multiply the single-digit number by the digit in the tens place. Add any number you carried over from the previous step.
- Step 3 (Multiply the Hundreds): Multiply the single-digit number by the digit in the hundreds place. Again, add any carried-over number to find the final product.
2. What grade is 3 digit by 1 digit multiplication?
The multiplication of a 3-digit number by a 1-digit number is a core mathematical concept typically taught in Grade 4.
This topic is a standard part of the Class 4 Maths curriculum for CBSE and other educational boards. It builds on basic multiplication facts and introduces students to more complex calculations, including multiplication with regrouping.
3. What is regrouping in multiplication?
Regrouping in multiplication, often called carrying over, is the process of moving a value from one place value column to the next higher column when the product in a column is 10 or more.
- For example, in the problem 245 x 4, multiplying 4 x 5 gives 20.
- You write the 0 in the ones place of the answer.
- You carry over the 2 to the tens place, to be added after multiplying the tens digit.
- This printable multiplication worksheet provides ample practice on sums that require regrouping.

9. How is place value important in multiplying 3-digit numbers by 1-digit numbers?
Understanding place value is critical for correctly solving 3-digit by 1-digit multiplication problems.
It ensures that each part of the product is aligned in the correct column (ones, tens, hundreds). For example, when you multiply the single digit by the tens digit of the three-digit number, the result must be recorded in the tens place. This alignment is especially crucial when carrying over, as it prevents errors and leads to the correct final answer.
10. What is the best way to explain multiplication to a grade 4 learner?
The best way to explain multiplication to a Grade 4 learner is to present it as a quick method for repeated addition, supported by visual and practical examples.
- Use Real-World Context: Frame questions as simple stories, like calculating the total number of items in multiple groups.
- Visual Aids: Use drawings or arrays to show how multiplication combines equal groups.
- Structured Practice: A vertical multiplication worksheet like this helps break down the process into manageable steps, making concepts like regrouping easier to grasp.
