How to Subtract Whole Tens from 3-Digit Numbers Easily
FAQs on Class 3 Maths Worksheet: Subtracting Whole Tens from 3-Digit Numbers
1. How do you subtract whole numbers like whole tens from 3-digit numbers step-by-step?
To subtract whole tens from a 3-digit number, you focus only on the tens place value. This method avoids complex borrowing and makes subtraction much faster for Class 3 students.
Here are the steps:
- Step 1: Identify the digit in the tens place of the 3-digit number. For example, in 485, the tens digit is 8.
- Step 2: Look at the whole ten you are subtracting. For example, in 30, you are subtracting 3 tens.
- Step 3: Subtract the tens digits: 8 – 3 = 5.
- Step 4: Keep the hundreds and ones digits the same. The new number becomes 455.
2. What is an example of subtraction for Class 3?
A perfect example of subtraction for Class 3 is subtracting a multiple of ten from a 3-digit number without regrouping. This type of problem builds foundational skills in understanding place value.
Here are some examples from the subtract whole tens from 3-digit numbers topic:
- If you have 263 and need to subtract 40, the answer is 223.
- Subtracting 30 from 589 gives you 559.
- Taking away 50 from 971 results in 921.

4. Does this worksheet on subtracting whole tens include an answer key?
Yes, this subtraction worksheet for Grade 3 comes with a complete answer key. Including the solutions is important for effective learning and helps both parents and students.
The answer key allows you to:
- Quickly check your child's answers for accuracy.
- Help students identify and correct their own mistakes.
- Build confidence by allowing for independent self-assessment.
5. What skills are built by solving subtraction word problems for Class 3?
Subtraction word problems are a crucial part of the Class 3 Maths syllabus because they build essential real-world skills beyond basic calculation. They help students understand the practical application of subtraction.
Key skills developed include:
- Reading Comprehension: Students learn to read a problem carefully and identify key information.
- Analytical Thinking: They must figure out what the question is asking and which operation (subtraction) to use.
- Problem-Solving: It teaches a step-by-step approach to finding a solution to a real-life scenario.
6. How does understanding place value help in subtracting whole tens?
Understanding place value is the most important skill needed for subtracting whole tens from 3-digit numbers easily. It allows students to perform the calculation mentally without needing to write it out in a vertical format.
Here's why it's crucial:
- It helps a child see a number like 762 as 7 hundreds, 6 tens, and 2 ones.
- When subtracting a whole ten like 40 (which is 4 tens), the student knows they only need to change the tens column.
- This turns a complex-looking problem like 762 - 40 into a simple sum: 6 tens - 4 tens, making the answer 722.
7. Is this subtraction worksheet for Class 3 available as a free printable PDF?
Yes, absolutely. This Class 3 Maths worksheet on subtracting whole tens from 3-digit numbers is available as a free, downloadable PDF. We believe in providing accessible educational resources for all students.
This format is beneficial because it is:
- Easy to Access: You can download it instantly with one click.
- Printable: Perfect for hands-on practice at home or in the classroom.
- Cost-Effective: There is no charge, making it a great resource for parents and teachers.
8. What are 'whole tens' in mathematics?
Whole tens, also known as multiples of 10, are numbers that you get by counting in tens. They are fundamental in early mathematics for understanding place value and simplifying calculations like addition and subtraction.
Examples of whole tens include:
- 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, and so on.
A key feature is that they always have a zero in the ones place.
9. How can this worksheet help my child get faster at mental maths?
This worksheet is specifically designed to improve mental maths skills by focusing on a simple, repeatable subtraction pattern. Regular practice helps students perform calculations in their head instead of relying on paper.
It builds speed by:
- Reinforcing Place Value: Students quickly learn to isolate and subtract only the tens digit.
- Building Muscle Memory: Repeatedly solving problems like 548 - 20 makes the process automatic.
- Boosting Confidence: As students solve sums faster, their confidence in their math abilities grows, encouraging them to tackle more complex problems.
10. What is the difference between subtracting whole tens and subtraction with borrowing?
The main difference lies in the complexity of the calculation. This worksheet focuses on subtracting whole tens, which typically does not require borrowing or regrouping.
- Subtracting Whole Tens: This involves a simple subtraction in the tens column. For example, in 375 - 50, you just do 7-5 in the tens place to get 325. The ones digit is not affected.
- Subtraction with Borrowing: This is needed when the top digit in a column is smaller than the bottom digit. For example, in 375 - 56, you cannot subtract 6 from 5 in the ones column, so you must borrow from the tens place.
