The task involves interpreting place value blocks to determine the total number of blocks represented in each image. Place value blocks typically consist of:
-
Hundreds blocks: Large squares representing 100 units each.
-
Tens blocks: Long rectangles representing 10 units each.
-
Ones blocks: Small individual squares representing 1 unit each.
Let's solve each problem step by step:
---
Problem 1:
-
Hundreds blocks: 2
-
Tens blocks: 2
-
Ones blocks: 1
Calculation:
\[
2 \times 100 + 2 \times 10 + 1 \times 1 = 200 + 20 + 1 = 221
\]
Answer: 221 blocks

Problem 2:
-
Hundreds blocks: 1
-
Tens blocks: 5
-
Ones blocks: 3
Calculation:
\[
1 \times 100 + 5 \times 10 + 3 \times 1 = 100 + 50 + 3 = 153
\]
Answer: 153 blocks
---
Problem 3:
-
Hundreds blocks: 2
-
Tens blocks: 4
-
Ones blocks: 5
Calculation:
\[
2 \times 100 + 4 \times 10 + 5 \times 1 = 200 + 40 + 5 = 245
\]
Answer: 245 blocks
---
Problem 4:
-
Hundreds blocks: 3
-
Tens blocks: 0
-
Ones blocks: 4
Calculation:
\[
3 \times 100 + 0 \times 10 + 4 \times 1 = 300 + 0 + 4 = 304
\]
Answer: 304 blocks
---
Problem 5:
-
Hundreds blocks: 1
-
Tens blocks: 8
-
Ones blocks: 4
Calculation:
\[
1 \times 100 + 8 \times 10 + 4 \times 1 = 100 + 80 + 4 = 184
\]
Answer: 184 blocks
---
Problem 6:
-
Hundreds blocks: 2
-
Tens blocks: 5
-
Ones blocks: 2
Calculation:
\[
2 \times 100 + 5 \times 10 + 2 \times 1 = 200 + 50 + 2 = 252
\]
Answer: 252 blocks
---
Problem 7:
-
Hundreds blocks: 5
-
Tens blocks: 1
-
Ones blocks: 8
Calculation:
\[
5 \times 100 + 1 \times 10 + 8 \times 1 = 500 + 10 + 8 = 518
\]
Answer: 518 blocks
---
Problem 8:
-
Hundreds blocks: 4
-
Tens blocks: 6
-
Ones blocks: 7
Calculation:
\[
4 \times 100 + 6 \times 10 + 7 \times 1 = 400 + 60 + 7 = 467
\]
Answer: 467 blocks
---
Final Answers:
\[
\boxed{221, 153, 245, 304, 184, 252, 518, 467}
\]
