Problem Description:
The image shows a worksheet titled "Tens & Ones," which is designed to help students understand place value. Each row contains two columns labeled "Tens" and "Ones." The "Tens" column has vertical lines representing groups of ten, and the "Ones" column has individual squares representing single units.
The task is to count the total number of tens and ones in each row and determine the total value for each row.

Solution:
#### Step 1: Understand the Place Value System
-
Tens: Each vertical line represents a group of 10.
-
Ones: Each square represents a single unit (1).
#### Step 2: Count Tens and Ones for Each Row
##### Row 1:
-
Tens: There are 2 vertical lines, so there are 2 tens (2 × 10 = 20).
-
Ones: There are 3 squares, so there are 3 ones (3 × 1 = 3).
-
Total: 20 + 3 = 23.
##### Row 2:
-
Tens: There are 4 vertical lines, so there are 4 tens (4 × 10 = 40).
-
Ones: There are 5 squares, so there are 5 ones (5 × 1 = 5).
-
Total: 40 + 5 = 45.
##### Row 3:
-
Tens: There are 3 vertical lines, so there are 3 tens (3 × 10 = 30).
-
Ones: There are 7 squares, so there are 7 ones (7 × 1 = 7).
-
Total: 30 + 7 = 37.
##### Row 4:
-
Tens: There are 5 vertical lines, so there are 5 tens (5 × 10 = 50).
-
Ones: There are 2 squares, so there are 2 ones (2 × 1 = 2).
-
Total: 50 + 2 = 52.
##### Row 5:
-
Tens: There are 6 vertical lines, so there are 6 tens (6 × 10 = 60).
-
Ones: There are 4 squares, so there are 4 ones (4 × 1 = 4).
-
Total: 60 + 4 = 64.
##### Row 6:
-
Tens: There are 7 vertical lines, so there are 7 tens (7 × 10 = 70).
-
Ones: There are 8 squares, so there are 8 ones (8 × 1 = 8).
-
Total: 70 + 8 = 78.

Final Answer:
The totals for each row are as follows:
1.
23
2.
45
3.
37
4.
52
5.
64
6.
78
$$
\boxed{23, 45, 37, 52, 64, 78}
$$
