Place Value worksheet for learning tens and ones with expanded form practice.

Problem Explanation:

The task involves breaking down each given number into its tens and ones place values and then writing the expanded form of the number. Here's a step-by-step breakdown of how to solve it:

#### Key Concepts:
1. Tens Place: The digit in the tens place represents how many groups of 10 are in the number.
2. Ones Place: The digit in the ones place represents the remaining units.
3. Expanded Form: Writing the number as the sum of its tens and ones components.

#### Steps to Solve:
For each number:
- Identify the digit in the tens place.
- Identify the digit in the ones place.
- Write the expanded form by adding the value of the tens place (multiplied by 10) and the value of the ones place.

Solution:

#### Number: 14
- Tens: 1 (because there is 1 group of 10)
- Ones: 4 (because there are 4 units left)
- Expanded Form: \(10 + 4 = 14\)

#### Number: 18
- Tens: 1 (because there is 1 group of 10)
- Ones: 8 (because there are 8 units left)
- Expanded Form: \(10 + 8 = 18\)

#### Number: 15
- Tens: 1 (because there is 1 group of 10)
- Ones: 5 (because there are 5 units left)
- Expanded Form: \(10 + 5 = 15\)

#### Number: 12
- Tens: 1 (because there is 1 group of 10)
- Ones: 2 (because there are 2 units left)
- Expanded Form: \(10 + 2 = 12\)

#### Number: 11
- Tens: 1 (because there is 1 group of 10)
- Ones: 1 (because there is 1 unit left)
- Expanded Form: \(10 + 1 = 11\)

#### Number: 19
- Tens: 1 (because there is 1 group of 10)
- Ones: 9 (because there are 9 units left)
- Expanded Form: \(10 + 9 = 19\)

Filled Table:

| Number | Tens and Ones | Expanded Form |
|--------|-----------------------|---------------------|
| 14 | 1 tens | 10 + 4 = 14 |
| | 4 ones | |
| 18 | 1 tens | 10 + 8 = 18 |
| | 8 ones | |
| 15 | 1 tens | 10 + 5 = 15 |
| | 5 ones | |
| 12 | 1 tens | 10 + 2 = 12 |
| | 2 ones | |
| 11 | 1 tens | 10 + 1 = 11 |
| | 1 ones | |
| 19 | 1 tens | 10 + 9 = 19 |
| | 9 ones | |
