To solve the problem, we need to count the place value blocks in each row and determine the total number represented by those blocks. Place value blocks typically include:
-
Cubes (thousands): Represent 1,000 each.
-
Flats (hundreds): Represent 100 each.
-
Rods (tens): Represent 10 each.
-
Units (ones): Represent 1 each.
Let's analyze each row step by step:
---
Row 1:
-
Cubes (thousands): 2 cubes → \(2 \times 1,000 = 2,000\)
-
Flats (hundreds): 3 flats → \(3 \times 100 = 300\)
-
Rods (tens): 5 rods → \(5 \times 10 = 50\)
-
Units (ones): 1 unit → \(1 \times 1 = 1\)
Total for Row 1:
\[
2,000 + 300 + 50 + 1 = 2,351
\]
---
Row 2:
-
Cubes (thousands): 1 cube → \(1 \times 1,000 = 1,000\)
-
Flats (hundreds): 4 flats → \(4 \times 100 = 400\)
-
Rods (tens): 7 rods → \(7 \times 10 = 70\)
-
Units (ones): 6 units → \(6 \times 1 = 6\)
Total for Row 2:
\[
1,000 + 400 + 70 + 6 = 1,476
\]
---
Row 3:
-
Cubes (thousands): 2 cubes → \(2 \times 1,000 = 2,000\)
-
Flats (hundreds): 6 flats → \(6 \times 100 = 600\)
-
Rods (tens): 8 rods → \(8 \times 10 = 80\)
-
Units (ones): 5 units → \(5 \times 1 = 5\)
Total for Row 3:
\[
2,000 + 600 + 80 + 5 = 2,685
\]
---
Row 4:
-
Cubes (thousands): 4 cubes → \(4 \times 1,000 = 4,000\)
-
Flats (hundreds): 3 flats → \(3 \times 100 = 300\)
-
Rods (tens): 0 rods → \(0 \times 10 = 0\)
-
Units (ones): 0 units → \(0 \times 1 = 0\)
Total for Row 4:
\[
4,000 + 300 + 0 + 0 = 4,300
\]
---
Row 5:
-
Cubes (thousands): 3 cubes → \(3 \times 1,000 = 3,000\)
-
Flats (hundreds): 5 flats → \(5 \times 100 = 500\)
-
Rods (tens): 6 rods → \(6 \times 10 = 60\)
-
Units (ones): 0 units → \(0 \times 1 = 0\)
Total for Row 5:
\[
3,000 + 500 + 60 + 0 = 3,560
\]
---
Row 6:
-
Cubes (thousands): 2 cubes → \(2 \times 1,000 = 2,000\)
-
Flats (hundreds): 4 flats → \(4 \times 100 = 400\)
-
Rods (tens): 9 rods → \(9 \times 10 = 90\)
-
Units (ones): 3 units → \(3 \times 1 = 3\)
Total for Row 6:
\[
2,000 + 400 + 90 + 3 = 2,493
\]
---
Final Answers:
\[
\boxed{2351, 1476, 2685, 4300, 3560, 2493}
\]
