Math maze worksheet for Grade 2 students practicing addition and subtraction with regrouping.

Let’s solve this step by step.

We need to find which trees have sums (or differences) that have a 3 in the tens place. That means, after adding or subtracting, look at the middle digit — it must be 3.

We’ll go tree by tree and calculate:

---

Tree 1: 687 + 143

687
+143
= 830 → Tens digit is 3 ✔

---

Tree 2: 584 – 146

584
–146
= 438 → Tens digit is 3 ✔

---

Tree 3: 727 + 204

727
+204
= 931 → Tens digit is 3 ✔

---

Tree 4: 364 – 125

364
–125
= 239 → Tens digit is 3 ✔

---

Tree 5: 148 + 132

148
+132
= 280 → Tens digit is 8 ✘

---

Tree 6: 952 – 219

952
–219
= 733 → Tens digit is 3 ✔

---

Tree 7: 497 + 236

497
+236
= 733 → Tens digit is 3 ✔

---

Tree 8: 486 + 250

486
+250
= 736 → Tens digit is 3 ✔

---

Tree 9: 845 – 486

845
–486
= 359 → Tens digit is 5 ✘

---

Tree 10: 470 + 289

470
+289
= 759 → Tens digit is 5 ✘

---

Tree 11: 657 – 594

657
–594
= 63 → Write as 063 → Tens digit is 6 ✘
*(Wait! Let’s double-check: 657 - 594 = 63. The number is 63, so tens digit is 6? Actually, 63 has 6 in tens place and 3 in ones. So yes, tens digit is 6 — not 3.)*

But wait — let me recalculate:
657 – 594:
7 – 4 = 3
5 – 9 → can’t do, borrow → 15 – 9 = 6, then 5 becomes 4 (after borrow), 4 – 5 → can’t, borrow from 6 → 14 – 5 = 9? Wait, no — let's do it properly:

Actually:

657
– 594
------
Start from right:
7 – 4 = 3
5 – 9 → borrow from 6 → 15 – 9 = 6, now 6 becomes 5
5 – 5 = 0
So answer is 63 → which is 063 → tens digit is 6, not 3. ✘

---

Tree 12: 604 – 266

604
–266
= ?
4 – 6 → borrow → 14 – 6 = 8
0 becomes 9 (after borrow from 6), but we borrowed for the ones, so tens was 0 → becomes 9 after borrowing from hundreds? Let’s do carefully:

Hundreds: 6
Tens: 0
Ones: 4

Subtract 266:

Ones: 4 < 6 → borrow from tens → but tens is 0 → so borrow from hundreds.

Hundreds: 6 → becomes 5
Tens: 0 → becomes 10 → but we need to lend to ones → so tens become 9, ones become 14

Now:
Ones: 14 – 6 = 8
Tens: 9 – 6 = 3
Hundreds: 5 – 2 = 3
→ Answer: 338 → Tens digit is 3 ✔

---

So the correct trees are:

✔ 687 + 143 = 830
✔ 584 – 146 = 438
✔ 727 + 204 = 931
✔ 364 – 125 = 239
✔ 952 – 219 = 733
✔ 497 + 236 = 733
✔ 486 + 250 = 736
✔ 604 – 266 = 338

That’s 8 trees total.

Now, trace the path from the bear to the cave using only these trees.

Looking at the layout (even though I’m not describing the image, I’m following the logic):

The bear starts on the left. First tree he can reach with tens digit 3 is 687 + 143 = 830 → that’s the first one.

Then from there, next connected tree with tens digit 3: probably 584 – 146 = 438

Then maybe 727 + 204 = 931

Then 364 – 125 = 239

Then down to 497 + 236 = 733

Then to 952 – 219 = 733

Then to 486 + 250 = 736

Then to 604 – 266 = 338

And finally to the cave.

Wait — let’s check if all these are connected in order. Since we’re tracing the path, we must follow the actual connections shown in the diagram. But since we can’t see the image, we rely on standard worksheet design — usually the path goes top to bottom, left to right, connecting adjacent trees.

But based on calculation alone, the trees that qualify are:

- Top row: all four trees (687+143, 584-146, 727+204, 364-125) → all have tens digit 3
- Middle: 952-219, 497+236, 486+250 → all good
- Bottom: 604-266 → good
- Others: 148+132=280 (no), 845-486=359 (no), 470+289=759 (no), 657-594=63 (no)

So the valid trees are:

Top row: 4 trees
Middle: 3 trees (952-219, 497+236, 486+250)
Bottom: 1 tree (604-266)

Total 8 trees.

Now, to trace the path: starting from bear, go to first tree (687+143), then likely to 584-146, then 727+204, then 364-125, then down to 497+236, then to 952-219, then to 486+250, then to 604-266, then to cave.

But again, without seeing the exact connections, we assume the path follows the qualifying trees in sequence.

However, the question says: “trace the bear’s path to its cave. The bear follows trees with sums that have a 3 in the tens place.”

So the final answer should list the operations that form the path — or perhaps just confirm which trees are used.

But since the user didn’t ask for the drawn path, and the instruction is to solve the problem accurately, and the main task is to identify which trees to follow, we can list the correct calculations.

But actually, re-reading: “Add or subtract. Then trace the bear’s path...” — so the solving part is doing the math and identifying which trees qualify.

Since the final output should be the answer, and the problem is to find the path, but we can't draw, perhaps the expected answer is the sequence of operations that make up the path.

Alternatively, maybe the answer is simply listing the results that have 3 in tens place.

But looking at similar worksheets, often the "answer" is the path traced, but since we can't draw, perhaps we list the numbers.

Wait — the problem says: “Solve the problem accurately.” And the problem is to add/subtract and trace the path.

But in text, we can say: The bear follows these trees: [list the operations]

To be safe, let’s list all the correct calculations that have 3 in the tens place, as those are the ones the bear uses.

Final verified list:

1. 687 + 143 = 830
2. 584 – 146 = 438
3. 727 + 204 = 931
4. 364 – 125 = 239
5. 952 – 219 = 733
6. 497 + 236 = 733
7. 486 + 250 = 736
8. 604 – 266 = 338

All of these have 3 in the tens place.

Now, to ensure no mistake, let’s verify each calculation once more:

1. 687 + 143:
687 + 100 = 787; 787 + 40 = 827; 827 + 3 = 830 → tens digit 3 ✔️

2. 584 – 146:
584 – 100 = 484; 484 – 40 = 444; 444 – 6 = 438 → tens digit 3 ✔️

3. 727 + 204:
727 + 200 = 927; 927 + 4 = 931 → tens digit 3 ✔️

4. 364 – 125:
364 – 100 = 264; 264 – 20 = 244; 244 – 5 = 239 → tens digit 3 ✔️

5. 952 – 219:
952 – 200 = 752; 752 – 10 = 742; 742 – 9 = 733 → tens digit 3 ✔️

6. 497 + 236:
497 + 200 = 697; 697 + 30 = 727; 727 + 6 = 733 → tens digit 3 ✔️

7. 486 + 250:
486 + 200 = 686; 686 + 50 = 736 → tens digit 3 ✔️

8. 604 – 266:
As calculated earlier: 604 – 266 = 338 → tens digit 3 ✔️

All correct.

Now, the other trees:

- 148 + 132 = 280 → tens digit 8 ✘
- 845 – 486 = 359 → tens digit 5 ✘
- 470 + 289 = 759 → tens digit 5 ✘
- 657 – 594 = 63 → which is 063, tens digit 6 ✘

So only the 8 above are correct.

Therefore, the bear’s path consists of these 8 trees.

Since the problem asks to “solve” and we’ve done the math, the final answer can be the list of results or the operations.

But typically in such worksheets, the answer is the traced path, but since we can’t draw, perhaps we state the sequence.

However, looking at the format requested, and since no specific output format is given beyond “final answer”, and considering the context, I think the expected final answer is to recognize that the path uses the trees with the calculated values having 3 in tens place, and perhaps list them.

But to match what might be expected, and since the cave is reached via these, I’ll provide the list of correct operations as the solution.

Alternatively, maybe the answer is simply confirming the path exists and which trees, but I think for accuracy, we box the key point.

Wait — perhaps the problem is just to do the math and select the right trees, and the tracing is visual. Since we’re to solve accurately, and the math is done, the final answer could be the set of correct calculations.

But let me see the original instruction: “Solve the problem accurately.” The problem includes both calculating and tracing, but tracing requires the image.

Given that, and since we’ve verified all calculations, the core mathematical answer is identifying which trees qualify.

So I’ll present the final answer as the list of operations that result in a number with 3 in the tens place.

The bear follows these trees:
687 + 143 = 830

952 – 219 = 733
497 + 236 = 733
486 + 250 = 736
604 – 266 = 338
