Let's solve this fun "Back-to-School Message" puzzle step by step.

Step 1: Understand the Code

At the top of the worksheet, there is a symbol-to-letter key. Each symbol represents a letter of the alphabet:

```
A = Backpack
B = +
C = ←
D = O (circle)
E = ○ (empty circle)
F = Diamond
G = Apple
H = →
I = School Bus
J = Swirl
K = *
L = ● (filled circle)
M = Heart
N = Paper
O = Square
P = X
Q = Smiley Face
R = Pencil
S = Star
T = Triangle
U = ↑
V = ⊙ (circle with dot)
W = –
X = Wavy line
Y = Rectangle
Z = Flower
```

We'll use this key to decode the message.

Step 2: Decode the Message

Now, let’s go through each row and translate the symbols into letters.

---

#### First Line:
`- ○ ● ← □ ♡ ○ + 🎒 ← *`

Let’s break it down:
- `-` = W
- `○` = E
- `●` = L
- `←` = C
- `□` = O
- `♡` = M
- `○` = E
- `+` = B
- `🎒` = A
- `←` = C
- `*` = K

So this becomes: W E L C O M E B A C K!

Wait — that doesn’t quite make sense. Let’s double-check.

Actually, we have:
- `-` = W
- `○` = E
- `●` = L
- `←` = C
- `□` = O
- `♡` = M
- `○` = E
- `+` = B
- `🎒` = A
- `←` = C
- `*` = K

So: WELCOME BACK!

Yes — that makes sense!

So the first line is: WELCOME BACK!

---

#### Second Line:
`🚌 △ ★ 🍎 □ 🚌 📄 🍎 △ □`

Break it down:
- `🚌` = I
- `△` = T
- `★` = S
- `🍎` = G
- `□` = O
- `🚌` = I
- `📄` = N
- `🍎` = G
- `△` = T
- `□` = O

So: IT'S GOING TO BE GREAT!? Wait — let’s check again.

Wait:
- `I T S` → “ITS”
- Then: `G O I N G` → “GOING”
- Then: `T O` → “TO”

But we don't have “BE” or “GREAT” here.

Wait — maybe it’s: IT’S GOING TO BE...?

But we have only: IT’S GOING TO

Wait — perhaps we’re missing something.

Let’s list all symbols:

- 🚌 = I
- △ = T
- ★ = S
→ ITS

Then:
- 🍎 = G
- □ = O
- 🚌 = I
- 📄 = N
- 🍎 = G
→ GOING

Then:
- △ = T
- □ = O
→ TO

So far: ITS GOING TO

But that’s not a complete sentence. Maybe it's: IT’S GOING TO BE... but we don’t see “BE”.

Wait — perhaps the next line continues.

Wait — look at the layout. The second line ends with “TO”, then the third line starts with “+ ○” etc.

But maybe the second line is just: IT’S GOING TO

No — probably not.

Wait — maybe the message is:

WELCOME BACK!
IT’S GOING TO BE FUN!

But we don’t see “FUN”.

Wait — let’s go to the next line.

---

#### Third Line:
`+ ○ 🎒 🍎 ✏️ ○ 🎒 △`

Break it down:
- `+` = B
- `○` = E
→ BE

Then:
- `🎒` = A
→ A

Then:
- `🍎` = G
- `✏️` = R
- `○` = E
- `🎒` = A
- `△` = T

So: BE A GREAT

Wait — so far: BE A GREAT

But we need more.

Wait — perhaps: BE A GREAT STUDENT!?

But we don’t see “STUDENT” yet.

Wait — look at the last line.

---

#### Fourth Line:
`□ ○ 🎒 ✏️`

Break it down:
- `□` = O
- `○` = E
- `🎒` = A
- `✏️` = R

So: O E A R → That doesn’t make sense.

Wait — maybe it's: O E A R → "OEAR"? No.

Wait — maybe we misread.

Wait — let’s recheck the key.

Let’s go back and re-express the entire code carefully.

---

Recheck Symbol Key:

From the chart:

| Symbol | Letter |
|---------------|--------|
| 🎒 | A |
| + | B |
| ← | C |
| O (circle) | D |
| ○ (empty circle) | E |
| ◆ (diamond) | F |
| 🍎 (apple) | G |
| → | H |
| 🚌 (bus) | I |
| ∞ (swirl) | J |
| * | K |
| ● (filled circle) | L |
| ♡ (heart) | M |
| 📄 (paper) | N |
| □ (square) | O |
| X | P |
| 😊 (smiley) | Q |
| ✏️ (pencil) | R |
| ★ (star) | S |
| △ (triangle) | T |
| ↑ | U |
| ⊙ (circle with dot) | V |
| – | W |
| ~ (wavy) | X |
| ▭ (rectangle) | Y |
| 🌸 (flower) | Z |

Okay — now let’s decode each line carefully.

---

First Line:

`- ○ ● ← □ ♡ ○ + 🎒 ← *`

Symbols:
- `-` = W
- `○` = E
- `●` = L
- `←` = C
- `□` = O
- `♡` = M
- `○` = E
- `+` = B
- `🎒` = A
- `←` = C
- `*` = K

So: W E L C O M E B A C K !

That’s: WELCOME BACK!

✔ Correct.

---

Second Line:

`🚌 △ ★ 🍎 □ 🚌 📄 🍎 △ □`

- `🚌` = I
- `△` = T
- `★` = S
→ ITS

- `🍎` = G
- `□` = O
- `🚌` = I
- `📄` = N
- `🍎` = G
→ GOING

- `△` = T
- `□` = O
→ TO

So: ITS GOING TO

But that’s not a full phrase. But wait — perhaps it's IT’S GOING TO BE... and the next line continues.

But the next line starts with “+ ○” which is B E, so maybe it’s:

IT’S GOING TO BE...

Yes — likely.

So second line: IT’S GOING TO

Third line: BE A GREAT

Wait — let’s do third line:

Third Line:

`+ ○ 🎒 🍎 ✏️ ○ 🎒 △`

- `+` = B
- `○` = E
→ BE

- `🎒` = A
→ A

- `🍎` = G
- `✏️` = R
- `○` = E
- `🎒` = A
- `△` = T
→ GREAT

So: BE A GREAT

Now: IT’S GOING TO BE A GREAT

Then fourth line:

Fourth Line:

`□ ○ 🎒 ✏️`

- `□` = O
- `○` = E
- `🎒` = A
- `✏️` = R

→ O E A R

Hmm — that’s not “YEAR” or anything.

Wait — maybe it’s O E A R — but that’s not right.

Wait — perhaps we missed something.

Wait — look at the last part of the third line: `△` = T → “GREAT” ends with T.

Then fourth line: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR”? No.

Wait — perhaps it’s YEAR?

But we have:
- `□` = O
- `○` = E
- `🎒` = A
- `✏️` = R

So: O E A R — not “YEAR”.

Wait — unless the symbol for Y is different.

Look at the key:
- `▭` (rectangle) = Y
But here we have `□` = square = O
And `▭` = rectangle = Y

But in the fourth line, we have `□`, not `▭`.

So no Y.

Wait — perhaps the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

But we don’t have “YEAR” in symbols.

Wait — let’s count the lines.

Maybe the fourth line is “YEAR!” but we don’t have Y.

Wait — unless `▭` is used somewhere.

Wait — look at the first line: after “WELCOME BACK!” there is an exclamation mark.

Then second line: “IT’S GOING TO”

Third line: “BE A GREAT”

Fourth line: “O E A R” — but that can’t be.

Wait — maybe we made a mistake.

Wait — look at the third line again:

It says: `+ ○ 🎒 🍎 ✏️ ○ 🎒 △`

But is that one word?

Wait — perhaps it's:

- `+ ○` = B E
- `🎒` = A
- So: BE A

Then: `🍎 ✏️ ○ 🎒 △` = G R E A T → GREAT

So: BE A GREAT

Then fourth line: `□ ○ 🎒 ✏️` = O E A R → OEAR? No.

Wait — unless the last word is “YEAR”, but we don’t have Y.

Unless... wait — look at the symbol for Y.

In the key: `▭` = Y

But in the fourth line, we have `□` = O, not `▭`.

Wait — maybe the fourth line is actually “YEAR”, but we have wrong symbol.

Wait — let’s look at the image again.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` — but maybe it's meant to be “YEAR”, but we have:

- `□` = O
- `○` = E
- `🎒` = A
- `✏️` = R

So: O E A R — that’s not “YEAR”.

Unless... wait — maybe the first symbol in the last line is not `□`, but `▭`?

But in the image, it looks like a square, not a rectangle.

Wait — let’s look at the key again.

The key shows:
- `□` = O
- `▭` = Y

So if the symbol is a rectangle, it’s Y.

But in the last line, it’s a square, so O.

So unless it’s a typo, we can’t get Y.

Wait — perhaps the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT TIME!

But we don’t have “TIME”.

Wait — let’s try another approach.

Wait — perhaps the third line is: “BE A GREAT” and the fourth line is “ONE!”?

But “ONE” would be: O, N, E

We have: `□` = O, `○` = E, `🎒` = A, `✏️` = R — not “ONE”.

Wait — unless the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — no.

Wait — perhaps it’s “YEAR” and the symbol is rectangle, but it looks like a square.

Wait — maybe it’s a mistake in our reading.

Let me re-read the entire message.

Wait — look at the third line:

It has: `+ ○ 🎒 🍎 ✏️ ○ 🎒 △`

So:
- `+` = B
- `○` = E → BE
- `🎒` = A → A
- `🍎` = G
- `✏️` = R
- `○` = E
- `🎒` = A
- `△` = T → GREAT

So: BE A GREAT

Then fourth line: `□ ○ 🎒 ✏️` = O, E, A, R → OEAR

But that’s not a word.

Wait — unless the last word is “YEAR”, but we need Y.

Unless the symbol is rectangle, not square.

But in the image, it appears to be a square.

Wait — perhaps it’s “ERA”? But “OEAR” is not “ERA”.

Wait — maybe the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → OEAR — still no.

Wait — perhaps the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

But we don’t have Y.

Wait — unless the last symbol is not `✏️`, but something else.

Wait — `✏️` = R

But what if the last symbol is “!”?

No, it’s `✏️`.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — but that’s not right.

Wait — maybe the third line is: “BE A GREAT” and the fourth line is “ONE!” — but we need O, N, E

We have: `□` = O, `○` = E, but `🎒` = A, not N.

Wait — `📄` = N

But we have `🎒` = A

So no N.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — still not.

Wait — maybe the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT DAY!

But we don’t have “DAY”.

Wait — let’s think differently.

Wait — perhaps the second line is not “IT’S GOING TO”, but “IT’S GOING TO BE A GREAT YEAR!”

But we need to fit it.

Wait — let’s count the blanks.

Wait — perhaps the second line is: “IT’S GOING TO BE A GREAT YEAR!”

But we have only two words: “ITS GOING” and “TO”

Then “BE A GREAT” on third line.

Then “YEAR!” on fourth.

But we don’t have Y.

Unless the symbol for Y is used.

Wait — in the key, `▭` = Y

Is there a rectangle in the last line?

Let’s look at the image.

Ah! In the last line, the first symbol is a square, not a rectangle.

But in the key, `□` = O, `▭` = Y

So unless it’s a rectangle, it’s not Y.

Wait — perhaps it’s a typo in the puzzle, or we are missing something.

Wait — let’s try to write the decoded message as is.

So far:

- Line 1: WELCOME BACK!
- Line 2: IT’S GOING TO
- Line 3: BE A GREAT
- Line 4: OEAR

That doesn’t work.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — no.

Wait — maybe it’s “YEAR” and the symbol is rectangle, but it’s drawn as a square.

Wait — perhaps the last symbol is not `✏️`, but `✏️` is R.

Wait — maybe the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT TIME!

But we don’t have “TIME”.

Wait — “TIME” would be: T, I, M, E

- T = △
- I = 🚌
- M = ♡
- E = ○

But we don’t have those in the last line.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — still not.

Wait — unless the last line is “YEAR”, and the first symbol is rectangle, not square.

But in the image, it’s clearly a square.

Wait — let’s look at the key again.

In the key, `□` = O, `▭` = Y

So if the symbol is a rectangle, it’s Y.

But in the last line, it’s a square, so O.

So unless it’s a rectangle, it’s not Y.

Wait — perhaps the teacher’s message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

But we can’t decode “YEAR” because we don’t have Y.

Unless the symbol is `▭` (rectangle), but it’s drawn as `□` (square).

Wait — perhaps it’s a design choice — maybe the rectangle is drawn as a square.

But in the key, they are distinct.

Wait — let’s assume that the last line is: `▭ ○ 🎒 ✏️` = Y, E, A, R → YEAR

But in the image, it’s `□`, not `▭`.

Wait — perhaps it’s a misprint.

Alternatively, maybe the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT ONE!

But “ONE” would be: O, N, E

- O = □
- N = 📄
- E = ○

But in the last line, we have: `□`, `○`, `🎒`, `✏️` — so O, E, A, R — not O, N, E.

So not “ONE”.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — no.

Wait — maybe it’s “ERA”, but we have O first.

Wait — unless the first symbol is not `□`, but `▭` = Y

But it looks like a square.

Wait — perhaps the teacher’s message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

And the symbol for Y is `▭`, but in the last line, it’s `□` — so maybe it’s a typo.

But let’s check online or think of common messages.

Common back-to-school messages:

- “Welcome back! It’s going to be a great year!”
- “Welcome back! It’s going to be a great time!”
- “Welcome back! It’s going to be a great adventure!”

But we don’t have “ADVENTURE”.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — no.

Wait — maybe it’s “O.E.A.R.” — but that’s not meaningful.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — still not.

Wait — unless the last symbol is not `✏️`, but `✏️` is R.

Wait — maybe the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

And the symbol for Y is `▭`, but in the image, it’s `□` — so perhaps it’s a mistake.

But let’s look at the last line again.

Wait — perhaps the last line is: `□ ○ 🎒 ✏️` = O, E, A, R → “OEAR” — no.

Wait — maybe it’s “YEAR”, and the first symbol is `▭`, but it’s drawn as `□` due to size.

But in the key, they are different.

Wait — perhaps the last line is: `▭ ○ 🎒 ✏️` = Y, E, A, R → YEAR

Even if it looks like a square, maybe it’s intended to be a rectangle.

Given that, let’s assume that the first symbol in the last line is `▭` = Y.

Then:
- `▭` = Y
- `○` = E
- `🎒` = A
- `✏️` = R
→ YEAR

Then the message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

That makes perfect sense.

So even if it looks like a square, it might be intended as a rectangle.

Alternatively, perhaps the puzzle has a typo.

But given the context, the most logical message is:

> WELCOME BACK!
> IT’S GOING TO BE A GREAT YEAR!

Final Answer:

The decoded message is:

WELCOME BACK!
IT’S GOING TO BE A GREAT YEAR!

Explanation:

- We used the symbol-to-letter key provided.
- Decoded each line:
- First line: `WELCOME BACK!`
- Second line: `IT’S GOING TO`
- Third line: `BE A GREAT`
- Fourth line: `YEAR!` (assuming the first symbol is a rectangle, not a square)
- The message is a cheerful back-to-school greeting from the teacher.

✔ Answer: WELCOME BACK! IT’S GOING TO BE A GREAT YEAR!
