Math worksheet for practicing place value by identifying the value of underlined digits in two-digit numbers.

It looks like you've uploaded a math worksheet titled "Underlined Digits", which has two parts:

---

🔹 Part 1: Write the value of the underlined digits.

In this section, each number has one digit underlined (though in your image, it's not visible which digits are underlined — but based on the red answers provided, we can infer what was intended).

Let’s go through each row and determine the value of the underlined digit.

We’ll assume that the underlined digit is the one that corresponds to the red answer given. For example, if the number is `23` and the red answer is `20`, then the tens digit (2) is underlined.

Let’s analyze:

#### Row 1:
- 23 → 20 (the 2 is underlined; value = 2 × 10 = 20)
- 98 → 90 (the 9 is underlined; value = 9 × 10 = 90)
- 87 → 80 (the 8 is underlined; value = 8 × 10 = 80)
- 65 → 60 (the 6 is underlined; value = 6 × 10 = 60)

#### Row 2:
- 23 → 3 (the 3 is underlined; value = 3 × 1 = 3)
- 91 → 90 (the 9 is underlined; value = 9 × 10 = 90)
- 53 → 50 (the 5 is underlined; value = 5 × 10 = 50)
- 51 → 50 (the 5 is underlined; value = 5 × 10 = 50)

#### Row 3:
- 45 → 40 (the 4 is underlined; value = 4 × 10 = 40)
- 10 → 10 (the 1 is underlined; value = 1 × 10 = 10)
- 11 → 10 (the 1 in tens place is underlined; value = 1 × 10 = 10)
- 33 → 30 (the 3 in tens place is underlined; value = 3 × 10 = 30)

#### Row 4:
- 15 → 5 (the 5 is underlined; value = 5 × 1 = 5)
- 37 → 7 (the 7 is underlined; value = 7 × 1 = 7)
- 98 → 90 (the 9 is underlined; value = 9 × 10 = 90)
- 42 → 2 (the 2 is underlined; value = 2 × 1 = 2)

#### Row 5:
- 75 → 70 (the 7 is underlined; value = 7 × 10 = 70)
- 43 → 40 (the 4 is underlined; value = 4 × 10 = 40)
- 36 → 6 (the 6 is underlined; value = 6 × 1 = 6)
- 19 → 9 (the 9 is underlined; value = 9 × 1 = 9)

✔ So, Part 1 asks for the place value of the underlined digit.

🔹 Part 2: Underline the correct digit in each number given its value.

Here, a number is given, and a value is shown in red. You must underline the digit in the number that has that value.

Let’s check each one:

| Number | Value Given | Explanation |
|--------|-------------|-----------|
| 13 | 10 | The digit 1 represents 10 → underline 1 ✔ |
| 55 | 50 | The first 5 is in tens place = 50 → underline 5 ✔ |
| 15 | 5 | The 5 is in ones place = 5 → underline 5 ✔ |
| 62 | 60 | The 6 is in tens place = 60 → underline 6 ✔ |
| 87 | 7 | The 7 is in ones place = 7 → underline 7 ✔ |
| 40 | 40 | The 4 is in tens place = 40 → underline 4 ✔ |
| 47 | 40 | The 4 is in tens place = 40 → underline 4 ✔ |
| 14 | 4 | The 4 is in ones place = 4 → underline 4 ✔ |
| 59 | 50 | The 5 is in tens place = 50 → underline 5 ✔ |
| 75 | 5 | The 5 is in ones place = 5 → underline 5 ✔ |
| 66 | 60 | The first 6 is in tens place = 60 → underline 6 ✔ |
| 30 | 0 | The 0 is in ones place = 0 → underline 0 ✔ |
| 28 | 8 | The 8 is in ones place = 8 → underline 8 ✔ |
| 53 | 3 | The 3 is in ones place = 3 → underline 3 ✔ |
| 11 | 1 | Either 1 is worth 1, but since both are 1s, either could be underlined, but likely the ones digit is intended → underline 1 ✔ |
| 16 | 10 | The 1 is in tens place = 10 → underline 1 ✔ |
| 24 | 20 | The 2 is in tens place = 20 → underline 2 ✔ |
| 99 | 9 | The second 9 is in ones place = 9 → underline 9 ✔ |
| 90 | 0 | The 0 is in ones place = 0 → underline 0 ✔ |
| 90 | 90 | The 9 is in tens place = 90 → underline 9 ✔ |

✔ All answers match the red values provided.

✔ Final Summary:

This worksheet teaches place value:
- In Part 1, students find the value of an underlined digit.
- In Part 2, students identify which digit corresponds to a given value.

All answers in red are correct based on standard place value rules.

📌 Example Rule Recap:

- In a two-digit number:
- Tens digit: value = digit × 10
- Ones digit: value = digit × 1

For example:
- In 47, the 4 is worth 40, the 7 is worth 7.
