Math worksheet for learning place value, focusing on tens and ones by counting squares.

Problem Description:

The task involves counting the number of squares in each box and expressing the total as a combination of "TENS" and "ONES." The goal is to practice place value concepts, specifically tens and ones.

Solution Approach:

1. Understand the Structure:
- Each box contains a grid of squares.
- The squares are organized into rows and columns.
- We need to count the total number of squares in each box and express it as a combination of "TENS" and "ONES."

2. Counting Strategy:
- Count the number of squares in each row.
- Multiply the number of squares per row by the number of rows to get the total number of squares.
- Express the total as a combination of "TENS" and "ONES":
- TENS: The number of complete groups of 10 squares.
- ONES: The remaining squares after accounting for the TENS.

3. Step-by-Step Solution:
Let's analyze each box one by one:

#### Box 1:
- Rows: 2
- Squares per row: 5
- Total squares: \( 2 \times 5 = 10 \)
- Place value: \( 1 \) TEN and \( 0 \) ONES

#### Box 2:
- Rows: 3
- Squares per row: 4
- Total squares: \( 3 \times 4 = 12 \)
- Place value: \( 1 \) TEN and \( 2 \) ONES

#### Box 3:
- Rows: 2
- Squares per row: 6
- Total squares: \( 2 \times 6 = 12 \)
- Place value: \( 1 \) TEN and \( 2 \) ONES

#### Box 4:
- Rows: 3
- Squares per row: 3
- Total squares: \( 3 \times 3 = 9 \)
- Place value: \( 0 \) TENS and \( 9 \) ONES

#### Box 5:
- Rows: 4
- Squares per row: 2
- Total squares: \( 4 \times 2 = 8 \)
- Place value: \( 0 \) TENS and \( 8 \) ONES

#### Box 6:
- Rows: 5
- Squares per row: 1
- Total squares: \( 5 \times 1 = 5 \)
- Place value: \( 0 \) TENS and \( 5 \) ONES

#### Box 7:
- Rows: 3
- Squares per row: 5
- Total squares: \( 3 \times 5 = 15 \)
- Place value: \( 1 \) TEN and \( 5 \) ONES

#### Box 8:
- Rows: 4
- Squares per row: 3
- Total squares: \( 4 \times 3 = 12 \)
- Place value: \( 1 \) TEN and \( 2 \) ONES

#### Box 9:
- Rows: 2
- Squares per row: 7
- Total squares: \( 2 \times 7 = 14 \)
- Place value: \( 1 \) TEN and \( 4 \) ONES

#### Box 10:
- Rows: 5
- Squares per row: 2
- Total squares: \( 5 \times 2 = 10 \)
- Place value: \( 1 \) TEN and \( 0 \) ONES

Final Answer:

\[
\boxed{
\begin{array}{c|c}
\text{Box} & \text{TENS and ONES} \\
\hline
1 & 1 \text{ TEN}, 0 \text{ ONES} \\
2 & 1 \text{ TEN}, 2 \text{ ONES} \\
3 & 1 \text{ TEN}, 2 \text{ ONES} \\
4 & 0 \text{ TENS}, 9 \text{ ONES} \\
5 & 0 \text{ TENS}, 8 \text{ ONES} \\
6 & 0 \text{ TENS}, 5 \text{ ONES} \\
7 & 1 \text{ TEN}, 5 \text{ ONES} \\
8 & 1 \text{ TEN}, 2 \text{ ONES} \\
9 & 1 \text{ TEN}, 4 \text{ ONES} \\
10 & 1 \text{ TEN}, 0 \text{ ONES} \\
\end{array}
