Expanded form, 1st & 2nd grade | 1st grade, 2nd grade Math ... - Free Printable

Problem Analysis:

The task involves two main parts:
1. Writing numbers in expanded form: Breaking down each number into tens and ones.
2. Finding missing numbers: Completing equations where one part is missing.

Let's solve each part step by step.

Part 1: Writing Numbers in Expanded Form

#### Instructions:
Write each number as a sum of tens and ones.

#### Given Numbers:
- 54
- 47
- 29
- 62
- 25
- 12
- 29
- 51
- 93
- 24
- 85
- 11
- 66
- 19
- 36

#### Solution:
To write a number in expanded form, separate it into its tens and ones place values. For example:
- 54 = 50 (tens) + 4 (ones)
- 47 = 40 (tens) + 7 (ones)
- 29 = 20 (tens) + 9 (ones)
- 62 = 60 (tens) + 2 (ones)
- 25 = 20 (tens) + 5 (ones)
- 12 = 10 (tens) + 2 (ones)
- 29 = 20 (tens) + 9 (ones)
- 51 = 50 (tens) + 1 (ones)
- 93 = 90 (tens) + 3 (ones)
- 24 = 20 (tens) + 4 (ones)
- 85 = 80 (tens) + 5 (ones)
- 11 = 10 (tens) + 1 (ones)
- 66 = 60 (tens) + 6 (ones)
- 19 = 10 (tens) + 9 (ones)
- 36 = 30 (tens) + 6 (ones)

#### Filled Table:
| Number | Expanded Form |
|--------|---------------|
| 54 | 50 + 4 |
| 47 | 40 + 7 |
| 29 | 20 + 9 |
| 62 | 60 + 2 |
| 25 | 20 + 5 |
| 12 | 10 + 2 |
| 29 | 20 + 9 |
| 51 | 50 + 1 |
| 93 | 90 + 3 |
| 24 | 20 + 4 |
| 85 | 80 + 5 |
| 11 | 10 + 1 |
| 66 | 60 + 6 |
| 19 | 10 + 9 |
| 36 | 30 + 6 |

Part 2: Finding Missing Numbers

#### Instructions:
Complete the equations by finding the missing numbers.

#### Given Equations:
1. \( \_\_ + 6 = 86 \)
2. \( \_\_ + 3 = 33 \)
3. \( 10 + \_\_ = 15 \)
4. \( 20 + \_\_ = 22 \)
5. \( \_\_ + 3 = 43 \)
6. \( 92 - \_\_ = 92 \)
7. \( \_\_ + 1 = 61 \)
8. \( \_\_ + 8 = 58 \)
9. \( 50 + \_\_ = 29 \)
10. \( 92 - \_\_ = 94 \)

#### Solution:
We solve each equation step by step:

1. \( \_\_ + 6 = 86 \)
Subtract 6 from 86:
\( 86 - 6 = 80 \)
So, the missing number is 80.

2. \( \_\_ + 3 = 33 \)
Subtract 3 from 33:
\( 33 - 3 = 30 \)
So, the missing number is 30.

3. \( 10 + \_\_ = 15 \)
Subtract 10 from 15:
\( 15 - 10 = 5 \)
So, the missing number is 5.

4. \( 20 + \_\_ = 22 \)
Subtract 20 from 22:
\( 22 - 20 = 2 \)
So, the missing number is 2.

5. \( \_\_ + 3 = 43 \)
Subtract 3 from 43:
\( 43 - 3 = 40 \)
So, the missing number is 40.

6. \( 92 - \_\_ = 92 \)
The only number that, when subtracted from 92, gives 92 is 0.
So, the missing number is 0.

7. \( \_\_ + 1 = 61 \)
Subtract 1 from 61:
\( 61 - 1 = 60 \)
So, the missing number is 60.

8. \( \_\_ + 8 = 58 \)
Subtract 8 from 58:
\( 58 - 8 = 50 \)
So, the missing number is 50.

9. \( 50 + \_\_ = 29 \)
Subtract 50 from 29:
\( 29 - 50 = -21 \)
So, the missing number is -21.

10. \( 92 - \_\_ = 94 \)
Subtract 92 from 94:
\( 94 - 92 = 2 \)
So, the missing number is -2 (since subtracting a negative is equivalent to adding).

| \( 20 + \_\_ = 22 \) | 2 |
| \( \_\_ + 3 = 43 \) | 40 |
| \( 92 - \_\_ = 92 \) | 0 |
| \( \_\_ + 1 = 61 \) | 60 |
| \( \_\_ + 8 = 58 \) | 50 |
| \( 50 + \_\_ = 29 \) | -21 |
| \( 92 - \_\_ = 94 \) | -2 |
