Let’s solve this step by step.

This is a 4-Digit Addition Riddle Worksheet called “The Lazy Skeleton.” The goal is to:

1. Add the 4-digit numbers in each box (labeled A–T).
2. Match the sum to the corresponding letter.
3. Fill in the blanks at the bottom with the correct letters to solve the riddle:
> *What do you call a skeleton who won’t work?*

Step 1: Calculate all the sums

We’ll go box by box and compute the total for each.

---

#### Box E:
```
1,375
4,567
1,298
+ 345
-------
```
Add step by step:

- 1,375 + 4,567 = 5,942
- 5,942 + 1,298 = 7,240
- 7,240 + 345 = 7,585

✔ E = 7,585

---

#### Box B:
```
4,504
5,671
1,891
+ 6,388
-------
```

- 4,504 + 5,671 = 10,175
- 10,175 + 1,891 = 12,066
- 12,066 + 6,388 = 18,454

✔ B = 18,454

---

#### Box F:
```
8,888
2,222
999
+ 4,444
-------
```

- 8,888 + 2,222 = 11,110
- 11,110 + 999 = 12,109
- 12,109 + 4,444 = 16,553

✔ F = 16,553

---

#### Box N:
```
6,543
4,299
7,802
+ 5,786
-------
```

- 6,543 + 4,299 = 10,842
- 10,842 + 7,802 = 18,644
- 18,644 + 5,786 = 24,430

✔ N = 24,430

---

#### Box S:
```
7,981
9,255
8,998
+ 778
-------
```

- 7,981 + 9,255 = 17,236
- 17,236 + 8,998 = 26,234
- 26,234 + 778 = 27,012

✔ S = 27,012

---

#### Box A:
```
4,556
4,676
4,876
+ 4,567
-------
```

- 4,556 + 4,676 = 9,232
- 9,232 + 4,876 = 14,108
- 14,108 + 4,567 = 18,675

✔ A = 18,675

---

#### Box Y:
```
3,465
9,876
1,203
+ 5,023
-------
```

- 3,465 + 9,876 = 13,341
- 13,341 + 1,203 = 14,544
- 14,544 + 5,023 = 19,567

✔ Y = 19,567

---

#### Box G:
```
1,987
2,654
3,321
+ 4,098
-------
```

- 1,987 + 2,654 = 4,641
- 4,641 + 3,321 = 7,962
- 7,962 + 4,098 = 12,060

✔ G = 12,060

---

#### Box L:
```
5,673
6,753
3,567
+ 776
-------
```

- 5,673 + 6,753 = 12,426
- 12,426 + 3,567 = 15,993
- 15,993 + 776 = 16,769

✔ L = 16,769

---

Step 2: Match sums to letters

Now we have:

| Letter | Sum |
|--------|---------|
| E | 7,585 |
| B | 18,454 |
| F | 16,553 |
| N | 24,430 |
| S | 27,012 |
| A | 18,675 |
| Y | 19,567 |
| G | 12,060 |
| L | 16,769 |

---

Step 3: Fill in the blanks using the answer key at the bottom

The riddle line has these numbers:

> 16,769 18,675 16,553 19,567 18,454 12,060 24,430 7,585 27,012

We match each number to its letter:

- 16,769 → L
- 18,675 → A
- 16,553 → F
- 19,567 → Y
- 18,454 → B
- 12,060 → G
- 24,430 → N
- 7,585 → E
- 27,012 → S

So the answer is:

> L A F Y B G N E S

Step 4: Solve the riddle

Rearranged, that spells:

> LAZY BONES

Which is the classic pun answer to:

> *What do you call a skeleton who won’t work?*
> 👉 Lazy Bones!

*(Because skeletons are made of bones — so a lazy skeleton = lazy bones!)*

---

✔ Final Answer:

Lazy Bones
