Part 1: Revision (numbers 13–30)
We need to fill in the missing letters to complete the number words.

- 13 → TH_RTEEN → THIRTEEN
- 14 → F_U__TEEN → FOURTEEN
- 15 → FI_T_EN → FIFTEEN
- 16 → S_XT_EN → SIXTEEN
- 17 → S_V_NTEEN → SEVENTEEN
- 18 → E_GH_EEN → EIGHTEEN
- 19 → N_N_TEEN → NINETEEN
- 20 → T_EN_Y → TWENTY
- 21 → TWENTY - _N_ → TWENTY-ONE
- 22 → TWENTY - __O → TWENTY-TWO
- 25 → TWENTY - F_V_ → TWENTY-FIVE
- 30 → T_IR_Y → THIRTY

✔ All filled correctly.

Part 2: Write numbers
Match the word to the numeral.

Given words: eighty, thirty, seventy, ten, sixty, twenty, forty, ninety, fifty, a hundred

Now match:

- 10 → ten ✔ (already done)
- 20 → twenty
- 30 → thirty
- 40 → forty
- 50 → fifty
- 60 → sixty
- 70 → seventy
- 80 → eighty
- 90 → ninety
- 100 → a hundred

✔ Straightforward matching.

Part 3: Solve the crossword

This is a bit trickier. We have clues with arrows pointing to boxes, and we must write the English word for the number in those boxes. The colored squares at the bottom are likely hints or keys — but since they’re not labeled clearly, let’s focus on the clues given.

Clues:

→ 50 → [5 boxes] → “fifty” → fits in 5 boxes? Let’s check:
“fifty” = 5 letters → ✔ fits.

→ 100 → [7 boxes] → “one hundred” → that’s 10 characters including space… too long. But maybe just “hundred”? That’s 7 letters → ✔ fits.

Wait — look again:
The clue says “100” with an arrow to a row of 7 boxes. So probably “hundred” (7 letters).

But let’s list all clues:

Left side:

- 50 → 5 boxes → fifty
- 70 → 7 boxes → seventy (7 letters) ✔
- 12 → 6 boxes → twelve (6 letters) ✔
- 11 → 6 boxes → eleven (6 letters) ✔

Right side:

- 60 → 6 boxes → sixty → only 5 letters ✘
Wait — maybe it’s “sixty” + something? Or perhaps I miscounted.

Look at the grid layout:

Actually, looking at the structure:

There are two columns of grids.

Left column:

- Top: 50 → 5 boxes → “fifty”
- Below that: 70 → 7 boxes → “seventy”
- Then 12 → 6 boxes → “twelve”
- Then 11 → 6 boxes → “eleven”

Right column:

- Top: 100 → 7 boxes → “hundred” (since “one hundred” is too long)
- Below: 60 → 6 boxes → “sixty” is 5 letters… doesn’t fit. Wait — maybe “sixty” with a space? No. Perhaps it’s “sixty” and one box is extra? Unlikely.

Wait — maybe the right-side clues are:

Looking again:

After 100 (7 boxes), there’s:

- 60 → 6 boxes → should be “sixty” → 5 letters → problem.

Unless... maybe it’s “sixty” and the last box is for something else? Or perhaps I’m misreading.

Alternative idea: Maybe the numbers correspond to the *position* in the alphabet? No, that seems overcomplicated.

Wait — look at the bottom row:

It shows colored blocks with letters:
[light blue][pink][green][green][yellow][blue] x [orange][lime green][gray][brown] B [red][red]

And below that, some numbers point to positions:

For example:

- 40 → points to first box of a 6-box row → which has yellow in second position? Not clear.

Perhaps the colored squares are meant to help decode the crossword answers via letter positions?

Another approach: Maybe the crossword is designed so that when you write the number words, the colored squares spell out something.

But without more context, let’s assume standard spelling.

Let me re-express all required answers based on standard English number words:

Crossword clues:

Left side:

- 50 → 5 letters → fifty
- 70 → 7 letters → seventy
- 12 → 6 letters → twelve
- 11 → 6 letters → eleven

Right side:

- 100 → 7 letters → hundred (commonly used alone for 100 in such contexts)
- 60 → 6 boxes → “sixty” is 5 letters → maybe it’s “sixty” and one box is blank? Or perhaps it’s “sixty” with a trailing space? Unlikely.

Wait — what if 60 is written as “sixty” and the sixth box is for the next word? But no other clue.

Alternatively, maybe it’s “sixty” and the grid allows for 6 boxes — perhaps one is unused? But that’s odd.

Another thought: In British English, sometimes “and” is included, e.g., “one hundred and sixty”, but that’s longer.

Wait — look at the diagram again mentally:

The right side has:

- 100 → 7 boxes → “hundred”
- Then below: 60 → 6 boxes → perhaps “sixty” is accepted even though it’s 5 letters? Maybe the sixth box is for punctuation? Unlikely.

Perhaps I made a mistake — let’s count letters:

“sixty” = s-i-x-t-y → 5 letters.

But the box has 6 spaces. Hmm.

What about “sixty” with a silent ‘e’? No.

Wait — maybe it’s “sixty” and the last box is for the next digit? But no.

Alternative idea: Perhaps the number 60 corresponds to “sixty”, and the grid is actually 5 boxes? But the image shows 6.

Since this is ambiguous, and given that in many worksheets, they might accept “sixty” in 6 boxes by leaving one blank or adding a space, but that’s not ideal.

Wait — another possibility: Maybe “60” is meant to be “sixty”, and the sixth box is for the letter from the key at the bottom.

Look at the bottom row:

It has colored squares with letters underneath or associated:

From left to right:

Positions 1 to 14? Let's index them:

Box 1: light blue → ?
Box 2: pink → ?
Box 3: green → ?
Box 4: green → ?
Box 5: yellow → ?
Box 6: blue → ?
Then 'x'
Box 7: orange → ?
Box 8: lime green → ?
Box 9: gray → ?
Box 10: brown → ?
Box 11: B → already has 'B'
Box 12: red → ?
Box 13: red → ?

And then there are arrows pointing to specific boxes in the crossword grids, like:

- 40 → points to first box of a 6-box row (which is under 20?)
Actually, looking back:

There’s a section:

```
[ ][Y][ ][ ][ ][ ] ← 40 points here?
20 [ ][C][ ][ ][ ][ ] ← 20 points here?
```

Wait, the user wrote:

"40 → [first box of a 6-box row]" — but in the text description, it's:

"40 → [box with yellow in second position?]"

Actually, in the original problem statement, it's described as:

"40 → [a row of 6 boxes, with the second box being yellow]"

Similarly, "20 → [a row of 6 boxes, with the second box being cyan/blue]"

And "80 → [a row of 8 boxes, first box red]"

Also, "90 → [a row of 7 boxes]"

And "60 → [a row of 6 boxes, first two colored: orange and gray]"

This suggests that the colored squares in the crossword grids correspond to the colored squares at the bottom, which have letters assigned.

So perhaps the bottom row is a key:

Let’s assign letters to colors based on common associations or perhaps the letters shown.

In the bottom row, after the 'x', there’s a 'B' in one box.

List the bottom sequence with indices:

Assume the bottom row has 14 positions:

Pos 1: light blue
Pos 2: pink
Pos 3: green
Pos 4: green
Pos 5: yellow
Pos 6: blue
Pos 7: x (maybe separator)
Pos 8: orange
Pos 9: lime green
Pos 10: gray
Pos 11: brown
Pos 12: B (so letter B)
Pos 13: red
Pos 14: red

But pos 12 has 'B', so perhaps each color corresponds to a letter, and 'B' is given for brown? Or for the 12th position?

This is getting complicated.

Perhaps the 'B' is indicating that the brown square represents the letter 'B'.

Similarly, maybe other colors represent letters.

But we don't have a full key.

Another idea: Perhaps the colored squares in the crossword grids indicate which letter goes there, based on the bottom key.

For example, in the 60 clue: first box is orange, second is gray.

If we can find what letter orange and gray represent from the bottom key.

In the bottom key, pos 8 is orange, pos 10 is gray.

But what letters are assigned to them? Not specified.

Unless the letters are implied by the position or something else.

Perhaps the bottom row spells out a word or phrase when read with the colors.

Let’s try to see if the colored squares in the crossword, when mapped to the bottom key, give us the letters.

But this is very vague.

Given the time, and since this is for a student, perhaps the intended answer is simply to write the number words in the boxes, ignoring the colors for now, or assuming the colors are decorative.

But that seems unlikely.

Let’s look for patterns.

Notice that in the bottom row, there is a 'B' at position 12, and before that, various colors.

Also, there is an 'x' at position 7.

Perhaps the 'x' means multiply or separate.

Another thought: Maybe the numbers like 40, 20, 80, etc., are not the values but the positions in the alphabet or something.

40th letter? Alphabet has only 26 letters.

Not likely.

Perhaps the number indicates how many letters, but we already did that.

Let’s go back to the crossword clues as per standard interpretation.

I think for a school-level worksheet, the expected answers are:

For the crossword:

- 50: fifty
- 70: seventy
- 12: twelve
- 11: eleven
- 100: hundred
- 60: sixty (even though 5 letters, perhaps they allow it or there's a typo)
- 90: ninety (6 letters, but the box has 7? Wait, 90 is listed with 7 boxes? Let's check.

In the user's description:

"90 → [7 boxes]"

"ninety" is 6 letters.

Same issue.

"80 → [8 boxes]" — "eighty" is 6 letters.

"40 → [6 boxes]" — "forty" is 5 letters.

"20 → [6 boxes]" — "twenty" is 6 letters! Ah!

"twenty" = t-w-e-n-t-y → 6 letters ✔

"forty" = f-o-r-t-y → 5 letters, but 6 boxes — problem.

"eighty" = e-i-g-h-t-y → 6 letters, but 8 boxes — problem.

"ninety" = n-i-n-e-t-y → 6 letters, 7 boxes — problem.

"sixty" = 5 letters, 6 boxes — problem.

"hundred" = 7 letters, 7 boxes ✔ for 100.

"fifty" = 5 letters, 5 boxes ✔ for 50.

"seventy" = 7 letters, 7 boxes ✔ for 70.

"twelve" = 6 letters, 6 boxes ✔ for 12.

"eleven" = 6 letters, 6 boxes ✔ for 11.

So for 20: "twenty" fits perfectly in 6 boxes.

For 40: "forty" is 5 letters, but 6 boxes — perhaps it's "forty" with a space or something.

Unless it's "fourty" — but that's incorrect spelling; correct is "forty".

Perhaps in some dialects, but no.

Another idea: Maybe for 40, it's "forty", and the sixth box is for the next thing, but there's no next clue.

Perhaps the number 40 is not the value but the clue for the position.

I think I need to make a decision.

Given that "twenty" fits for 20, and "hundred" for 100, etc., perhaps for the others, we use the correct spelling and assume the grid size is approximate or there's a mistake.

But let's notice that in the bottom row, there is a 'B' at position 12, and also 'x' at 7.

Perhaps the 'x' means that the seventh box is not used or is a separator.

Maybe the colored squares indicate that certain letters are fixed.

For example, in the 60 clue: first box orange, second gray.

If from the bottom key, orange is at position 8, gray at 10, but what letters?

Unless the bottom row is to be read as a sequence of letters corresponding to the colors.

But we don't have the mapping.

Perhaps the letters are given by the position in the alphabet of the color name or something — too complex.

Another approach: Perhaps the final answer is to fill in the number words, and the colors are for a different purpose, like checking.

But the instruction is "solve the crossword", so likely the words are to be written, and the colors might be for verification.

Given the constraints, I'll provide the standard number words for each clue, and for the ones with mismatched box sizes, I'll use the correct spelling and assume the grid can accommodate it or there's a minor error.

So:

- 50: fifty
- 70: seventy
- 12: twelve
- 11: eleven
- 100: hundred
- 60: sixty
- 90: ninety
- 80: eighty
- 40: forty
- 20: twenty

For the box sizes:

- 20: 6 boxes -> "twenty" fits
- 40: 6 boxes -> "forty" is 5, so perhaps "forty " with space, or maybe it's "fourty" (incorrect) — but I'll use "forty"
- 80: 8 boxes -> "eighty" is 6, so not fit
- 90: 7 boxes -> "ninety" is 6
- 60: 6 boxes -> "sixty" is 5

This is inconsistent.

Unless for 80, it's "eighty" and two spaces, but that's silly.

Perhaps the number indicates the starting position or something else.

Let's look at the arrows:

For example, "40 →" points to the first box of a 6-box row, and in that row, the second box is yellow.

Similarly, "20 →" points to the first box of another 6-box row, with second box cyan.

"80 →" points to the first box of an 8-box row, first box red.

"90 →" points to a 7-box row.

"60 →" points to a 6-box row with first two colored orange and gray.

Perhaps the colored boxes indicate that those positions have specific letters, and we need to use the bottom key to find what letter each color represents.

So let's try to decipher the bottom key.

Bottom row: 14 positions with colors and some letters.

Pos 1: light blue
Pos 2: pink
Pos 3: green
Pos 4: green
Pos 5: yellow
Pos 6: blue
Pos 7: x (perhaps not a letter)
Pos 8: orange
Pos 9: lime green
Pos 10: gray
Pos 11: brown
Pos 12: B (so letter B)
Pos 13: red
Pos 14: red

And pos 12 has 'B', so perhaps the brown color corresponds to 'B', since pos 11 is brown, pos 12 is B — maybe pos 12 is the letter for brown.

Similarly, perhaps each color has a letter, and 'B' is given for brown.

But what about others?

Perhaps the 'x' at pos 7 means that the seventh position is not used, and the letters are for the colors.

Another idea: Perhaps the bottom row is to be read as the letters for the colors in order, but with 'x' as separator.

So before 'x': positions 1-6: light blue, pink, green, green, yellow, blue — what letters?

After 'x': positions 8-14: orange, lime green, gray, brown, B, red, red — and pos 12 is 'B', so perhaps brown is 'B'.

Then red might be 'R', etc.

But we need to assign letters to colors.

Perhaps the letter is the first letter of the color name.

Let's try that:

- light blue: L or B? Usually "light blue" starts with L, but "blue" is B.
- pink: P
- green: G
- yellow: Y
- blue: B
- orange: O
- lime green: L or G
- gray: G
- brown: B
- red: R

But there are duplicates.

For example, green and lime green both could be G, gray also G.

Brown and blue both B.

Red is R.

In the bottom row, pos 12 is 'B', and pos 11 is brown, so perhaps brown = B.

Pos 6 is blue, and if blue = B, then conflict.

Pos 12 is explicitly 'B', so likely brown = B.

Then blue might be something else.

Perhaps the letter is given by the position.

Pos 1: light blue — letter A? (1st letter)

Pos 2: pink — B

Pos 3: green — C

Pos 4: green — D

Pos 5: yellow — E

Pos 6: blue — F

Pos 7: x — skip

Pos 8: orange — G

Pos 9: lime green — H

Pos 10: gray — I

Pos 11: brown — J

Pos 12: B — K? But it's 'B', not K.

Pos 12 has 'B', so perhaps it's not sequential.

This is not working.

Perhaps the 'B' at pos 12 means that the 12th position is 'B', and the colors correspond to letters based on their order.

I think I need to guess that for the crossword, the intended answers are the number words, and the colors are for a different part or for decoration.

Given that, and since the student needs to submit answers, I'll provide the number words for each clue.

So for Part 3:

- 50: fifty
- 70: seventy
- 12: twelve
- 11: eleven
- 100: hundred
- 60: sixty
- 90: ninety
- 80: eighty
- 40: forty
- 20: twenty

And for the box sizes, perhaps in the actual worksheet, the grids are sized correctly, or there's a mistake in my counting.

Perhaps "forty" is considered to have 6 letters in some contexts, but it doesn't.

Another possibility: For 40, it's "fourty" — although incorrect, some people spell it that way, but it's wrong.

I think for accuracy, I'll use the correct spellings.

So final answers for Part 3:

Write the following in the respective grids:

- 50: F I F T Y
- 70: S E V E N T Y
- 12: T W E L V E
- 11: E L E V E N
- 100: H U N D R E D
- 60: S I X T Y (and leave one box blank or add space)
- 90: N I N E T Y (6 letters, 7 boxes — same issue)
- 80: E I G H T Y (6 letters, 8 boxes)
- 40: F O R T Y (5 letters, 6 boxes)
- 20: T W E N T Y (6 letters, 6 boxes) ✔

For 20, it fits perfectly.

For 40, perhaps it's "forty" and the sixth box is for the next, but there's no next.

Perhaps the number 40 is not the value but the clue for the word "forty", and the grid is 6 boxes, so maybe it's "forty" with a period or something.

I recall that in some puzzles, they use "and" for numbers, but for 40, it's just "forty".

Perhaps for 80, it's "eighty", and the remaining boxes are for other things.

Given the time, I'll proceed with the standard answers.

So for the Final Answer, I'll list all parts.

First, Part 1: Fill in the blanks.

13: THIRTEEN
14: FOURTEEN
15: FIFTEEN
16: SIXTEEN
17: SEVENTEEN
18: EIGHTEEN
19: NINETEEN
20: TWENTY
21: TWENTY-ONE
22: TWENTY-TWO
25: TWENTY-FIVE
30: THIRTY

Part 2: Write numbers

10: ten
20: twenty
30: thirty
40: forty
50: fifty
60: sixty
70: seventy
80: eighty
90: ninety
100: a hundred

Part 3: Crossword

- 50: fifty
- 70: seventy
- 12: twelve
- 11: eleven
- 100: hundred
- 60: sixty
- 90: ninety
- 80: eighty
- 40: forty
- 20: twenty

Even though some don't fit the box sizes perfectly, this is the correct spelling.

Perhaps in the actual worksheet, the grids are sized appropriately, or the colors indicate that some letters are shared or something.

But for the purpose of this response, I'll go with this.

Final Answer:
