Addition Word Problems (Grade 3)
Addition word problems describe real-life situations where we need to find the total or combined amount. The key is to identify the numbers and decide that addition is the correct operation.
Words like "in all", "total", "altogether", "combined", "how many more were added" signal that addition is needed.
What is Addition Word Problems (Grade 3) - Class 3 Maths (Addition and Subtraction (Grade 3))?
A word problem is a maths question written as a story or real-life situation. To solve an addition word problem:
- Read the problem carefully.
- Identify the numbers and what is being asked.
- Decide the operation — look for clue words (total, altogether, in all, combined).
- Solve using column addition.
- Write the answer in a complete sentence with the correct unit.
Solved Examples
Example 1: Finding the Total
Question: A school has 356 boys and 278 girls. How many students are there in all?
Think:
- We need the total → add
- 356 + 278
- Ones: 6 + 8 = 14 → write 4, carry 1
- Tens: 5 + 7 + 1 = 13 → write 3, carry 1
- Hundreds: 3 + 2 + 1 = 6
Answer: The school has 634 students in all.
Example 2: Combining Two Groups
Question: Ria collected 185 seashells on Saturday and 247 seashells on Sunday. How many seashells did she collect altogether?
Think:
- Altogether → add: 185 + 247
- Ones: 5 + 7 = 12 → write 2, carry 1
- Tens: 8 + 4 + 1 = 13 → write 3, carry 1
- Hundreds: 1 + 2 + 1 = 4
Answer: Ria collected 432 seashells altogether.
Example 3: Adding Money
Question: Aman bought a cricket bat for ₹475 and a ball for ₹156. How much did he spend in total?
Think:
- Total → add: 475 + 156
- Ones: 5 + 6 = 11 → write 1, carry 1
- Tens: 7 + 5 + 1 = 13 → write 3, carry 1
- Hundreds: 4 + 1 + 1 = 6
Answer: Aman spent ₹631 in total.
Example 4: Adding Three Quantities
Question: In a mango orchard, there are 234 trees in Section A, 189 in Section B, and 312 in Section C. How many trees are there in all?
Think:
- 234 + 189 + 312
- Ones: 4 + 9 + 2 = 15 → write 5, carry 1
- Tens: 3 + 8 + 1 + 1 = 13 → write 3, carry 1
- Hundreds: 2 + 1 + 3 + 1 = 7
Answer: There are 735 trees in all.
Example 5: Distance Problem
Question: Kavi travelled 368 km by train and 245 km by bus. What was the total distance he travelled?
Think:
- Total distance → add: 368 + 245
- Ones: 8 + 5 = 13 → write 3, carry 1
- Tens: 6 + 4 + 1 = 11 → write 1, carry 1
- Hundreds: 3 + 2 + 1 = 6
Answer: Kavi travelled 613 km in total.
Example 6: More Were Added
Question: A shop had 463 packets of biscuits. They received 289 more packets. How many packets does the shop have now?
Think:
- "More" added to existing → add: 463 + 289
- Ones: 3 + 9 = 12 → write 2, carry 1
- Tens: 6 + 8 + 1 = 15 → write 5, carry 1
- Hundreds: 4 + 2 + 1 = 7
Answer: The shop has 752 packets now.
Example 7: Finding the Other Addend
Question: Priya read some pages of a book. She read 175 pages on Monday and some more on Tuesday. She read 412 pages in total. How many pages did she read on Tuesday?
Think:
- Total − Monday = Tuesday
- 412 − 175 = 237
Answer: Priya read 237 pages on Tuesday.
Example 8: Weight Problem
Question: A bag of rice weighs 456 g. A bag of dal weighs 378 g. What is the combined weight?
Think:
- Combined → add: 456 + 378
- Ones: 6 + 8 = 14 → write 4, carry 1
- Tens: 5 + 7 + 1 = 13 → write 3, carry 1
- Hundreds: 4 + 3 + 1 = 8
Answer: The combined weight is 834 g.
Example 9: Two-Step Problem
Question: Meera had ₹250. Her mother gave her ₹175 and her father gave her ₹300. How much money does Meera have now?
Think:
- Step 1: 250 + 175 = 425
- Step 2: 425 + 300 = 725
Answer: Meera has ₹725 now.
Example 10: School Attendance Problem
Question: On Monday, 498 students attended school. On Tuesday, 467 students attended. What was the total attendance for both days?
Think:
- 498 + 467
- Ones: 8 + 7 = 15 → write 5, carry 1
- Tens: 9 + 6 + 1 = 16 → write 6, carry 1
- Hundreds: 4 + 4 + 1 = 9
Answer: Total attendance was 965 students.
Real-World Applications
Types of addition word problems:
- Combining groups: 'A has 356 and B has 278. How many in all?' → 356 + 278.
- Adding more: 'A shop had 463 packets. They received 289 more.' → 463 + 289.
- Total of multiple groups: 'Section A has 234, B has 189, C has 312. Find total.' → 234 + 189 + 312.
- Finding a missing part: 'Total is 600. Part 1 is 375. What is Part 2?' → 600 − 375. (This uses subtraction, but the situation is about addition.)
Word problems connect mathematics to real life. They require reading comprehension along with arithmetic skills. Practise identifying the clue words to decide whether to add or subtract.
Key Points to Remember
- Look for clue words: total, altogether, in all, combined, how many now, how much more was added.
- Always read the problem twice before solving.
- Write the number sentence (e.g., 356 + 278 = ?) before calculating.
- Use column addition, regrouping when needed.
- Write the answer with the correct unit (₹, km, kg, students, etc.).
- Check your answer using estimation.

Frequently Asked Questions
Q1. How do I know when to add in a word problem?
Look for clue words like 'total', 'altogether', 'in all', 'combined', 'how many now', or 'how much together'. These signal that you need to add the given numbers.
Q2. What if the problem has three numbers?
Add all three numbers together. You can add two at a time, or write all three in columns and add each column.
Q3. Should I always use column addition?
For 3-digit numbers, column addition is the most reliable method. For simple problems (like 400 + 200), you can add mentally.
Q4. How do I check my answer to a word problem?
Use estimation to see if your answer is reasonable. You can also re-read the problem and verify that your answer makes sense in context.
Q5. What if the word problem uses 'more' — is it always addition?
Not always. 'How many more does A have than B' means subtraction (finding the difference). But 'A got 50 more' means addition. Read carefully to decide.
Q6. What units should I include in my answer?
Use the same unit as in the problem. If the problem talks about rupees, write ₹. If it mentions km, write km. Always include the unit.
Q7. Can word problems involve both addition and subtraction?
Yes. Multi-step problems may need both operations. Solve one step at a time.
Q8. What if I get a 4-digit answer from a 3-digit problem?
That is fine. The sum of two 3-digit numbers can exceed 999. For example, 750 + 380 = 1130. Just make sure your calculation is correct.
