Missing Number Chart 1-25 Worksheets for Kindergarten - Free Printable

Problem Description:

The task involves completing partially filled number charts from 1 to 25. The charts are designed for educational purposes, likely for young learners to practice number sequencing and counting.

Solution Approach:

To solve the problem, we need to fill in the missing numbers in both charts by following the sequence of numbers from 1 to 25. Each chart is a 5x5 grid, and the numbers should be filled in row-wise (left to right, top to bottom).

#### Chart 1 (Sheet 4):
The given numbers are:
- Row 1: `4`
- Row 2: `6`, `7`
- Row 3: `13`
- Row 4: `18`
- Row 5: `21`, `24`

We will fill in the missing numbers row by row.

1. Row 1: The first number is `4`. Since the sequence starts at 1, the previous numbers must be `1`, `2`, `3`. The next number after `4` is `5`.
- Filled Row 1: `1`, `2`, `3`, `4`, `5`

2. Row 2: The given numbers are `6` and `7`. The previous number before `6` is `5` (already filled), and the next number after `7` is `8`.
- Filled Row 2: `5`, `6`, `7`, `8`, `9`

3. Row 3: The given number is `13`. The numbers before `13` are `10`, `11`, `12`, and the number after `13` is `14`.
- Filled Row 3: `10`, `11`, `12`, `13`, `14`

4. Row 4: The given number is `18`. The numbers before `18` are `15`, `16`, `17`, and the number after `18` is `19`.
- Filled Row 4: `15`, `16`, `17`, `18`, `19`

5. Row 5: The given numbers are `21` and `24`. The number before `21` is `20`, the number between `21` and `24` is `22`, and the number after `24` is `25`.
- Filled Row 5: `20`, `21`, `22`, `24`, `25`

#### Completed Chart 1:
```
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
```

#### Chart 2 (Sheet 3):
The given numbers are:
- Row 1: `5`
- Row 2: `8`, `9`
- Row 3: `14`
- Row 4: `19`
- Row 5: `23`

We will fill in the missing numbers row by row.

1. Row 1: The given number is `5`. The previous numbers are `1`, `2`, `3`, `4`, and the next number is `6`.
- Filled Row 1: `1`, `2`, `3`, `4`, `5`

2. Row 2: The given numbers are `8` and `9`. The previous number before `8` is `7`, and the next number after `9` is `10`.
- Filled Row 2: `6`, `7`, `8`, `9`, `10`

3. Row 3: The given number is `14`. The numbers before `14` are `11`, `12`, `13`, and the number after `14` is `15`.
- Filled Row 3: `11`, `12`, `13`, `14`, `15`

4. Row 4: The given number is `19`. The numbers before `19` are `16`, `17`, `18`, and the number after `19` is `20`.
- Filled Row 4: `16`, `17`, `18`, `19`, `20`

5. Row 5: The given number is `23`. The numbers before `23` are `21`, `22`, and the number after `23` is `24`, `25`.
- Filled Row 5: `21`, `22`, `23`, `24`, `25`

#### Completed Chart 2:
```
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
```

Final Answer:

Both charts are completed as follows:

#### Chart 1 (Sheet 4):
```
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
```

#### Chart 2 (Sheet 3):
```
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
```
