Let’s solve each row step by step. We’re counting how many tens and ones are shown using base-10 blocks (long rods = tens, small cubes = ones).
---
First Row:
- Tens: There are 3 red rods → that’s
3 tens
- Ones: There are 2 blue cubes → that’s
2 ones
- So the number is: 30 + 2 =
32
Answer for first row:
→ 3 tens ___ 2 ones
→ 30 + 2 = 32
---
Second Row:
- Tens: There are 5 red rods →
5 tens
- Ones: There is 1 blue cube →
1 one
- Number: 50 + 1 =
51
Answer for second row:
→ 5 tens ___ 1 one
→ 50 + 1 = 51
---
Third Row:
- Tens: There are 4 red rods →
4 tens
- Ones: There are 6 blue cubes (arranged in a 2x3 grid) →
6 ones
- Number: 40 + 6 =
46
Answer for third row:
→ 4 tens ___ 6 ones
→ 40 + 6 = 46
---
Fourth Row:
- Tens: There are 3 red rods →
3 tens
- Ones: There are 7 blue cubes (a 2x3 grid plus 1 extra) →
7 ones
- Number: 30 + 7 =
37
Answer for fourth row:
→ 3 tens ___ 7 ones
→ 30 + 7 = 37
---
Now let’s write all answers clearly:
Final Answer:
Row 1: 3 tens, 2 ones → 30 + 2 = 32
Row 2: 5 tens, 1 one → 50 + 1 = 51
Row 3: 4 tens, 6 ones → 40 + 6 = 46
Row 4: 3 tens, 7 ones → 30 + 7 = 37
