Let's solve the "Missing Numbers 1–100" worksheet step by step.

Objective:

Fill in the missing numbers from 1 to 100 in the star grid, where some numbers are already provided as clues.

---

Step 1: Understand the Layout

The numbers are arranged in a grid of stars, with each row containing 10 stars (representing numbers 1–100). The pattern is sequential: left to right, top to bottom.

We need to fill in the missing numbers based on the sequence and the given clues.

---

Step 2: Identify Given Numbers

Let’s list the visible numbers and their positions:

- Row 1: 52, 55, 56
- Row 2: 58, 62, 65
- Row 3: 67, 71, 80
- Row 4: 73, 76, 83, 86
- Row 5: 88, 91, 93
- Row 6: 94, 100

Now let’s figure out which rows these numbers belong to.

Since the numbers go from 1 to 100, we can determine the row by dividing the number by 10:

- Numbers 1–10 → Row 1
- 11–20 → Row 2
- ...
- 91–100 → Row 10

But wait — looking at the image, there are only 6 rows of stars. That suggests that the grid may be showing only part of the 1–100 range.

Wait — actually, let's count the rows of stars:

- There are 6 rows of stars.
- Each row has 10 stars → total 60 stars.

But the numbers go up to 100, so this seems inconsistent.

Wait — perhaps it's not 6 full rows. Let's look again.

Actually, counting the rows:

1. Row 1: 52, 55, 56 → likely around 50s
2. Row 2: 58, 62, 65 → 50s–60s
3. Row 3: 67, 71, 80 → 60s–80s
4. Row 4: 73, 76, 83, 86 → 70s–80s
5. Row 5: 88, 91, 93 → 80s–90s
6. Row 6: 94, 100 → 90s–100

So the numbers range from 52 to 100, and they're spread across 6 rows.

Let’s determine how many numbers per row:

- 10 columns → 10 numbers per row
- So 6 rows = 60 numbers
- But the numbers start at 52 and end at 100 → that’s 100 - 52 + 1 = 49 numbers? No, that’s just the count of numbers from 52 to 100.

Wait — but there are 60 stars, so probably the grid is meant to represent numbers from 41 to 100 or something similar.

But let’s take a better approach.

Step 3: Deduce the Grid Structure

Looking at the numbers:

- First visible number: 52
- Last visible number: 100
- We see numbers like 52, 55, 56, 58, 62, 65, 67, 71, 73, 76, 80, 83, 86, 88, 91, 93, 94, 100

Let’s try to map them into a grid of 10 columns.

Assume the grid starts at 51 or 50?

Let’s suppose the first row starts at 51.

Then:
- Row 1: 51, 52, 53, 54, 55, 56, 57, 58, 59, 60
- Row 2: 61, 62, 63, 64, 65, 66, 67, 68, 69, 70
- Row 3: 71, 72, 73, 74, 75, 76, 77, 78, 79, 80
- Row 4: 81, 82, 83, 84, 85, 86, 87, 88, 89, 90
- Row 5: 91, 92, 93, 94, 95, 96, 97, 98, 99, 100

Now check if the given numbers fit:

- Row 1: 52, 55, 56 → yes, fits
- Row 2: 58 → no, 58 is in row 1 (last column), not row 2

Wait — 58 is in row 1? Then row 1 would be: 51–60

But then 58 is in row 1, column 8

Similarly, 62 is in row 2, column 2 → 61,62,...

But earlier I thought 58 was in row 2.

Let’s examine the image layout carefully.

From the image:

- The first row has: 52, 55, 56
- Second row: 58, 62, 65
- Third: 67, 71, 80
- Fourth: 73, 76, 83, 86
- Fifth: 88, 91, 93
- Sixth: 94, 100

Let’s assume the numbers are in order, increasing left to right, top to bottom.

So the grid is filled sequentially.

Let’s suppose the first number is 51, then:

Row 1: 51, 52, 53, 54, 55, 56, 57, 58, 59, 60
→ Given: 52, 55, 56 → matches

Row 2: 61, 62, 63, 64, 65, 66, 67, 68, 69, 70
→ Given: 58 → no, 58 is in row 1
But in the image, 58 appears in the second row!

Wait — contradiction.

So maybe the numbering doesn't start at 51.

Let’s suppose the first row starts at 50:

Row 1: 50, 51, 52, 53, 54, 55, 56, 57, 58, 59
→ Given: 52, 55, 56 → yes
Then 58 is in row 1, column 8 → but in image, 58 is in row 2

Wait — in the image, 58 is in the second row.

So if 58 is in row 2, then row 1 must have numbers less than 58.

Let’s suppose row 1 starts at 51:

Row 1: 51, 52, 53, 54, 55, 56, 57, 58, 59, 60
→ 52, 55, 56 → present → good
→ 58 is in row 1, column 8

But in the image, 58 is in the second row, so this can’t be.

Unless the rows are not consecutive.

Wait — perhaps the numbers are not starting from the beginning.

Let’s look at the positions:

From the image:

- First row: 52, 55, 56 → likely columns 2, 5, 6
- Second row: 58, 62, 65 → columns 1, 4, 7?
- Third: 67, 71, 80 → columns 1, 4, 10?
- Fourth: 73, 76, 83, 86 → columns 3, 6, 8, 10?
- Fifth: 88, 91, 93 → columns 1, 4, 6?
- Sixth: 94, 100 → columns 1, 10?

This suggests the grid is not continuous — but it should be.

Alternative idea: Perhaps the numbers are from 50 to 100, and the grid has 51 numbers, but there are 60 stars.

Wait — 100 - 50 + 1 = 51 numbers → too few.

Maybe it's from 41 to 100 → 60 numbers.

Yes! 100 - 41 + 1 = 60 numbers.

So likely the grid goes from 41 to 100, in 6 rows of 10 numbers.

Let’s test that.

Assumption: Grid is 41 to 100

- Row 1: 41–50
- Row 2: 51–60
- Row 3: 61–70
- Row 4: 71–80
- Row 5: 81–90
- Row 6: 91–100

Now check the given numbers:

- 52 → row 2, column 2 → yes
- 55 → row 2, column 5 → yes
- 56 → row 2, column 6 → yes
- 58 → row 2, column 8 → yes
- 62 → row 3, column 2 → yes
- 65 → row 3, column 5 → yes
- 67 → row 3, column 7 → yes
- 71 → row 4, column 1 → yes
- 73 → row 4, column 3 → yes
- 76 → row 4, column 6 → yes
- 80 → row 4, column 10 → yes
- 83 → row 5, column 3 → yes
- 86 → row 5, column 6 → yes
- 88 → row 5, column 8 → yes
- 91 → row 6, column 1 → yes
- 93 → row 6, column 3 → yes
- 94 → row 6, column 4 → yes
- 100 → row 6, column 10 → yes

Perfect! All given numbers fit.

So the grid is:

| Row | Numbers |
|-----|--------|
| 1 | 41–50 |
| 2 | 51–60 |
| 3 | 61–70 |
| 4 | 71–80 |
| 5 | 81–90 |
| 6 | 91–100 |

Now we can fill in all the missing numbers.

Step 4: Fill in the Missing Numbers

We’ll go row by row.

#### Row 1: 41–50

Given: none shown → all missing

So fill: 41, 42, 43, 44, 45, 46, 47, 48, 49, 50

#### Row 2: 51–60

Given: 52, 55, 56, 58

So missing: 51, 53, 54, 57, 59, 60

#### Row 3: 61–70

Given: 62, 65, 67

So missing: 61, 63, 64, 66, 68, 69, 70

#### Row 4: 71–80

Given: 71, 73, 76, 80

So missing: 72, 74, 75, 77, 78, 79

#### Row 5: 81–90

Given: 83, 86, 88

So missing: 81, 82, 84, 85, 87, 89, 90

#### Row 6: 91–100

Given: 91, 93, 94, 100

So missing: 92, 95, 96, 97, 98, 99

Final Answer: Complete the Grid

Here is the fully completed grid:

```
Row 1: 41 42 43 44 45 46 47 48 49 50
Row 2: 51 52 53 54 55 56 57 58 59 60
Row 3: 61 62 63 64 65 66 67 68 69 70
Row 4: 71 72 73 74 75 76 77 78 79 80
Row 5: 81 82 83 84 85 86 87 88 89 90
Row 6: 91 92 93 94 95 96 97 98 99 100
```

Now, you can fill in the stars accordingly.

✔ Summary

The missing numbers are all the integers from 41 to 100, arranged in order. Use the clues to verify the sequence and fill in the blanks.

For example:
- In row 2: after 52 comes 53, 54, then 55, etc.
- In row 3: 61, then 62, then 63, 64, 65, etc.

This ensures a complete sequence from 41 to 100.
