Problem Description:
The task involves counting the number of "tens" and "ones" in each group of objects shown in the image. The goal is to determine how many complete sets of ten (tens) and how many individual units (ones) are present in each group.
Solution Approach:
1.
Understanding the Structure:
- Each group consists of two columns: "Tens" and "Ones."
- The "Tens" column contains vertical lines, where each line represents a set of ten.
- The "Ones" column contains individual squares, where each square represents one unit.
2.
Counting the Tens:
- Count the number of vertical lines in the "Tens" column. Each line represents 10 units.
3.
Counting the Ones:
- Count the number of individual squares in the "Ones" column. Each square represents 1 unit.
4.
Combining the Results:
- Multiply the number of tens by 10.
- Add the number of ones to the result from step 4.
- Write the total as a number.
Step-by-Step Solution for Each Group:
#### Group 1:
-
Tens: There are 2 vertical lines.
-
Ones: There are 3 individual squares.
-
Calculation: \( 2 \times 10 + 3 = 23 \)
-
Answer: 23
#### Group 2:
-
Tens: There are 3 vertical lines.
-
Ones: There are 5 individual squares.
-
Calculation: \( 3 \times 10 + 5 = 35 \)
-
Answer: 35
#### Group 3:
-
Tens: There are 1 vertical line.
-
Ones: There are 7 individual squares.
-
Calculation: \( 1 \times 10 + 7 = 17 \)
-
Answer: 17
#### Group 4:
-
Tens: There are 2 vertical lines.
-
Ones: There are 6 individual squares.
-
Calculation: \( 2 \times 10 + 6 = 26 \)
-
Answer: 26
#### Group 5:
-
Tens: There are 3 vertical lines.
-
Ones: There are 8 individual squares.
-
Calculation: \( 3 \times 10 + 8 = 38 \)
-
Answer: 38
Final Answers:
1.
Group 1: 23
2.
Group 2: 35
3.
Group 3: 17
4.
Group 4: 26
5.
Group 5: 38
Boxed Final Answer:
\[
\boxed{23, 35, 17, 26, 38}
\]
