Let’s solve this step by step.

The task says:
> Use each hint to write a word that is only one letter different than the word above it.

We start with the word BALL at the top.
Then we go down through 6 clues, changing just ONE letter each time to make a new word.
Finally, we end with GOAL at the bottom.

So we need to find a chain of words:

1. Start: BALL
2. Clue 1 → Word 1 (1 letter different from BALL)
3. Clue 2 → Word 2 (1 letter different from Word 1)
4. Clue 3 → Word 3 (1 letter different from Word 2)
5. Clue 4 → Word 4 (1 letter different from Word 3)
6. Clue 5 → Word 5 (1 letter different from Word 4)
7. Clue 6 → GOAL (1 letter different from Word 5)

Let’s go clue by clue.

---

Clue 1: The opposite of short

“Short” opposite = “Tall”

Is “TALL” one letter different from “BALL”?
B → T → yes, only first letter changed.
✔ So Word 1 = TALL

---

Clue 2: The hind part of an animal

Hind part = “Tail”

Is “TAIL” one letter different from “TALL”?
L → I → second letter changed? Wait — TALL vs TAIL:
T-A-L-L vs T-A-I-L → third letter changed (L→I). Yes! Only one letter different.
✔ So Word 2 = TAIL

---

Clue 3: Put to sea

“Put to sea” = “Sail” (as in setting sail)

Is “SAIL” one letter different from “TAIL”?
T → S → first letter changed. Yes!
✔ So Word 3 = SAIL

---

Clue 4: Dirt

Dirt = “Soil”

Is “SOIL” one letter different from “SAIL”?
A → O → second letter changed. Yes!
✔ So Word 4 = SOIL

---

Clue 5: Spiral

Spiral = “Coil” (like a coiled spring)

Is “COIL” one letter different from “SOIL”?
S → C → first letter changed. Yes!
✔ So Word 5 = COIL

---

Clue 6: Dark mineral used for fuel

That’s “Coal”

Is “COAL” one letter different from “COIL”?
I → A → third letter changed. Yes!
✔ And “COAL” leads to “GOAL” — wait, no! The last word should be “GOAL”, and we’re going from COIL → COAL → then to GOAL?

Wait — let’s check the structure again.

Looking back at the worksheet:

After the 6 clues, the final word shown is GOAL, with blanks under G O A L.

But according to our chain:

BALL → TALL → TAIL → SAIL → SOIL → COIL → COAL

But we need to end at GOAL.

So perhaps the last step is from COIL to GOAL? But COIL → GOAL changes two letters: C→G and I→A. That’s not allowed.

Wait — maybe I made a mistake.

Let me recheck Clue 6: “Dark mineral used for fuel” → that’s definitely “Coal”.

But the final word on the sheet is “GOAL”, so maybe the chain ends with “GOAL”, meaning the last word before GOAL must be one letter different from GOAL.

So let’s reverse-engineer from GOAL.

What word is one letter different from GOAL and matches Clue 6?

Clue 6: Dark mineral used for fuel → Coal

Is “Coal” one letter different from “Goal”?
C vs G → first letter. Yes! Only one letter different.
So if Word 5 is “COAL”, then next is “GOAL” — but that would mean we have 7 words total? Let’s count:

Start: BALL
1. TALL
2. TAIL
3. SAIL
4. SOIL
5. COIL
6. COAL ← this should match Clue 6
Then final: GOAL ← but that’s extra?

Wait — looking at the worksheet layout:

There are 6 clues listed, and then after the last clue, there’s a row with “G O A L” — which suggests that the answer to the 6th clue should lead to GOAL, meaning the 6th word should be one letter different from GOAL.

But Clue 6 is “Dark mineral used for fuel” → COAL, and COAL is one letter different from GOAL (C vs G). Perfect!

So actually, the chain is:

BALL
↓ (change B→T)
TALL ← Clue 1: opposite of short
↓ (change L→I)
TAIL ← Clue 2: hind part of animal
↓ (change T→S)
SAIL ← Clue 3: put to sea
↓ (change A→O)
SOIL ← Clue 4: dirt
↓ (change S→C)
COIL ← Clue 5: spiral
↓ (change I→A)
COAL ← Clue 6: dark mineral for fuel
↓ (change C→G)
GOAL ← final word

But wait — the worksheet shows only 6 sets of blanks after the clues, and then GOAL at the bottom. So likely, the 6th clue’s answer is COAL, and then GOAL is the target, but not part of the chain? Or is GOAL the answer to the 6th clue?

No — Clue 6 is “Dark mineral used for fuel” → COAL, not GOAL.

But the worksheet has “G O A L” written at the bottom with blanks — probably indicating that the final word in the chain is GOAL, so the 6th word must be one letter different from GOAL.

Therefore, perhaps Clue 6’s answer is COAL, and then we change C to G to get GOAL — but that would be a 7th step.

Looking again at the image description:

It says: “Use each hint to write a word that is only one letter different than the word above it.”

And there are 6 hints, and then at the bottom, “G O A L” is shown — likely meaning that the last word you write (for hint 6) should be one letter different from GOAL.

But that doesn’t make sense because GOAL isn’t above it — the word above the last blank is the answer to hint 5.

Perhaps the structure is:

Start: BALL

Then for each of the 6 hints, you write a word below, each differing by one letter from the one above.

And the very last word (after 6 steps) should be GOAL.

So:

Step 0: BALL
Step 1: ? (clue 1)
Step 2: ? (clue 2)
Step 3: ? (clue 3)
Step 4: ? (clue 4)
Step 5: ? (clue 5)
Step 6: GOAL (clue 6)

So clue 6’s answer is GOAL? But GOAL is not a dark mineral.

That can’t be.

Unless... perhaps I misread.

Another possibility: the word “GOAL” at the bottom is not part of the chain, but rather the goal of the puzzle — like, you’re trying to reach “GOAL” from “BALL” in 6 steps, each changing one letter, and matching the clues.

But the clues are given for each step.

Let me list the clues again:

1. The opposite of short → TALL
2. The hind part of an animal → TAIL
3. Put to sea → SAIL
4. Dirt → SOIL
5. Spiral → COIL
6. Dark mineral used for fuel → COAL

And then from COAL to GOAL is one letter change (C to G), but that would be a 7th step.

But the worksheet has only 6 rows of blanks after the clues, and then “G O A L” at the bottom.

Perhaps “G O A L” is the answer to the 6th clue? But that doesn’t fit.

Unless... is there a word that means "dark mineral used for fuel" and is one letter different from GOAL?

GOAL → change G to C → COAL → yes, that works.

So if the 6th clue’s answer is COAL, and it’s written in the blanks, and then below it is GOAL as the final target, but not part of the chain.

But the instruction says: “use each hint to write a word that is only one letter different than the word above it.”

So for the first hint, write a word different from BALL.

For the second hint, write a word different from the first answer, and so on.

After 6 hints, you have 6 words.

Then at the bottom, “G O A L” is shown — perhaps as a check, or perhaps the last word should be GOAL.

But COAL is not GOAL.

Unless for clue 6, the answer is GOAL, but that doesn't make sense.

Perhaps "dark mineral used for fuel" is not coal? But it is.

Another idea: maybe "spiral" is not COIL, but something else.

Let's try a different path.

Start: BALL

Clue 1: opposite of short → TALL (B->T)

Clue 2: hind part of animal → TAIL (L->I)

Clue 3: put to sea → SAIL (T->S)

Clue 4: dirt → SOIL (A->O)

Clue 5: spiral → COIL (S->C)

Clue 6: dark mineral for fuel → COAL (I->A)

Now, from COAL to GOAL is C->G, but that's not part of the clues.

But the worksheet has "G O A L" at the bottom with blanks, suggesting that the final word is GOAL, so perhaps the 6th clue's answer should be one letter different from GOAL, and match the clue.

So for clue 6: "dark mineral used for fuel" — is there a word that is one letter different from GOAL and means that?

GOAL -> change G to C -> COAL -> yes.

So the answer to clue 6 is COAL, and it is written in the blanks, and then below it is GOAL as the final word, but not part of the chain.

But the instruction is to write a word for each hint that is one letter different from the word above it.

So for hint 6, the word above it is the answer to hint 5, which is COIL.

COIL to COAL is one letter change (I->A), and COAL matches clue 6.

Then, separately, GOAL is shown at the bottom, perhaps as the "goal" of the puzzle, or as a separate thing.

In the image, it's likely that the 6 answers are to be written in the blanks, and GOAL is the final target, but since COAL is one letter from GOAL, it fits.

So the chain is correct as:

BALL
TALL
TAIL
SAIL
SOIL
COIL
COAL

And then GOAL is the endpoint, but not part of the 6 steps.

But the worksheet has 6 sets of blanks for the 6 clues, and then "G O A L" at the bottom, so probably the last blank is for COAL, and GOAL is just there.

Perhaps for the 6th clue, the answer is GOAL, but that doesn't make sense.

Let's look for a word that means "dark mineral used for fuel" and is one letter different from the previous word.

Previous word is COIL (from clue 5: spiral).

COIL to what? If we change I to A, we get COAL, which is correct.

If we change C to G, we get GOIL, which is not a word.

Change O to A: CAIL, not a word.

Change L to A: COIA, not a word.

So only COAL works.

Therefore, the answers are:

1. TALL
2. TAIL
3. SAIL
4. SOIL
5. COIL
6. COAL

And then GOAL is the final word, which is one letter different from COAL, completing the "kick it" to goal.

So for the student, they should write:

For clue 1: TALL
Clue 2: TAIL
Clue 3: SAIL
Clue 4: SOIL
Clue 5: COIL
Clue 6: COAL

And the word GOAL is at the bottom as the finish line.

So the final answer for the blanks are those six words.

But the user asked to solve the problem, and the problem is to fill in the blanks.

So I think that's it.

Final Answer:
TALL, TAIL, SAIL, SOIL, COIL, COAL

But let's confirm the order.

The blanks are under each clue, so:

First blank (after clue 1): TALL
Second blank (after clue 2): TAIL
Third blank (after clue 3): SAIL
Fourth blank (after clue 4): SOIL
Fifth blank (after clue 5): COIL
Sixth blank (after clue 6): COAL

Yes.

And each is one letter different from the one above:

BALL to TALL: B->T
TALL to TAIL: L->I (third letter)
TAIL to SAIL: T->S
SAIL to SOIL: A->O
SOIL to COIL: S->C
COIL to COAL: I->A

Perfect.

And COAL to GOAL: C->G, but that's extra, not part of the clues.

So for the homework, the answers are as above.

Final Answer:
TALL
TAIL
SAIL
SOIL
COIL
COAL
