Grade 3 Math Word Problems Worksheet #3 - Mixed Practice with real-life scenarios.

I'll solve each word problem step by step.

Problem 1: Megan had 217 markers. Robert gave her 109 more markers. How many markers does Megan have altogether?
- Start with: 217
- Add: 109
- 217 + 109 = 326

Problem 2: A DVD book holds 14 DVDs. There are 81 DVDs already in the book. How many more DVDs can be put in the book?
- Total capacity: 14 × ? (need to find how many spaces total)
- Wait, let me re-read: "A DVD book holds 14 DVDs" - this means it holds 14 DVDs total per section/page
- Actually, I think it means the book has space for multiple sets of 14, and there are 81 already in it
- Let me reconsider: If it "holds 14 DVDs" and there are "81 DVDs already," we need to know the total capacity
- Hmm, I think the question might mean: if each page/section holds 14 DVDs, and there are 81 DVDs, how many more fit?
- Actually, rereading more carefully: I believe it's asking if the book holds a certain number total, and 81 are already in it
- Let me assume: The book holds some total number, 81 are in it, how many more?
- But it says "holds 14 DVDs" - maybe it means 14 pages × some number?
- I think the most reasonable interpretation: The book has a total capacity, and we need to figure out what that is from "holds 14 DVDs"
- Actually, I think it might be poorly worded, but likely means: The book can hold (14 × something) DVDs total, 81 are in it
- Or simpler: Maybe it's saying there are multiple sections that each hold 14, and we have 81 already
- Let me try: If each section holds 14, and we have 81 DVDs, then 81 ÷ 14 = 5 remainder 11, so 5 full sections plus 11 more
- To fill the next section: 14 - 11 = 3 more DVDs needed to complete that section
- But the question asks "how many MORE can be put in the book" - implying total remaining capacity
- I think I need to assume the book has a fixed total. Let me assume it holds 14 × 6 = 84 DVDs total (6 sections of 14)
- Then: 84 - 81 = 3 more DVDs can be added

Actually, let me reconsider the wording completely. "A DVD book holds 14 DVDs" - this could mean the entire book holds 14 DVDs total. But then having 81 already doesn't make sense.

I think the intended meaning is: Each page/section holds 14 DVDs, there are multiple pages, 81 DVDs are already placed, how many more can fit?

If 81 ÷ 14 = 5.78..., that's 5 full pages (70 DVDs) plus 11 on the 6th page
So the 6th page has room for 14 - 11 = 3 more DVDs
But we don't know how many total pages...

Let me try another interpretation: Perhaps it's a typo and should say "holds 140 DVDs" or similar?

Given the ambiguity, I'll go with the most common type of these problems: The book has a certain capacity, some are filled, find the remainder. If "holds 14 DVDs" means each compartment holds 14, and assuming a reasonable total like 84 (6 compartments), then 84 - 81 = 3.

Problem 3: Carla has some marbles. She bought 134 marbles. Now she has 277 marbles all together. How many did she start with?
- End amount: 277
- Added: 134
- Started with: 277 - 134 = 143

Problem 4: Paco had 93 cookies. He ate 15 of them. How many cookies did Paco have left?
- Start: 93
- Ate: 15
- Left: 93 - 15 = 78

Problem 5: Kelly has 121 Nintendo games. How many does she need to give away so that she will have 25 games left?
- Has: 121
- Want to have: 25
- Give away: 121 - 25 = 96

Problem 6: Connie had some marbles. She gave 189 to Juan. Now she has 500 marbles left. How many did she start with?
- Gave away: 189
- Has left: 500
- Started with: 500 + 189 = 689

Problem 7: Connie has 2315 red markers and 1028 blue markers. How many markers does she have altogether?
- Red: 2315
- Blue: 1028
- Total: 2315 + 1028 = 3343

Final Answer:
1. 326 markers
2. 3 DVDs (assuming the book holds 84 DVDs total in 6 sections of 14)
3. 143 marbles
4. 78 cookies
5. 96 games
6. 689 marbles
7. 3343 markers
