Step-by-Step Practice: 2-Digit by 1-Digit Column Multiplication Examples
FAQs on Multiply 1-Digit and 2-Digit Numbers in Columns for Class 3
1. How do you multiply a 1-digit number by a 2-digit number using the column method?
Multiplying a 2-digit number by a 1-digit number using the column method is a clear, step-by-step process that helps organise calculations. This method is also known as vertical multiplication.
- Step 1: Write the 2-digit number at the top and the 1-digit number below it, making sure the ones digits are aligned in the same column.
- Step 2: Multiply the bottom 1-digit number by the ones digit of the top number. Write the ones digit of the answer below the line.
- Step 3: If the answer from Step 2 is 10 or more, you must carry over the tens digit to the top of the next column (the tens column).
- Step 4: Multiply the bottom 1-digit number by the tens digit of the top number. Add the number you carried over to this result. Write the final number down.
2. What is 2-digit by 1-digit multiplication in Class 3 maths?
In Class 3 maths, 2-digit by 1-digit multiplication is a core arithmetic skill where a number with two digits (like 35) is multiplied by a number with one digit (like 5). This concept is usually taught using the column multiplication method to build a strong foundation in place value and the multiplication algorithm.

6. What is the best way for a Grade 3 student to practice column multiplication?
The most effective way for a Grade 3 student to practice column multiplication is through consistent and structured exercises. Start with a solid grasp of basic times tables, then use worksheets that offer plenty of problems to solve, beginning with sums that do not require carrying over and then progressing to more complex ones.
7. What does “carrying over” mean in column multiplication?
“Carrying over” in column multiplication is a fundamental step used when the product of digits in a column is 10 or greater. The tens digit of that product is moved or 'carried' to the next column to the left and added after the next multiplication step.
For example, in 36 × 4:
- First, multiply 4 × 6 = 24. Write down the '4' and carry over the '2' to the tens column.
- Next, multiply 4 × 3 = 12. Add the carried-over '2' to get 14.
- The final answer is 144.
8. Why is understanding place value important for multiplying in columns?
Understanding place value (the value of a digit based on its position, such as ones, tens, hundreds) is essential for success in column multiplication. It ensures that numbers are aligned correctly, and the results of each multiplication step are placed in the proper column, which is especially critical for managing the 'carry over' process accurately.
9. What skills are improved by practicing 2-digit by 1-digit multiplication?
Practicing 2-digit by 1-digit multiplication builds several crucial foundational maths skills for students. These worksheets specifically help improve:
- Calculation speed and mental maths ability.
- Understanding of the multiplication algorithm and place value.
- Confidence in handling multi-step arithmetic problems.
- Mastery of basic times tables and carrying over.
