Let's solve each question on the
"Hundreds, Tens and Ones Worksheet 1" by analyzing the base ten blocks shown in each section.
---
🔹 Understanding Base Ten Blocks:
-
Long rod (stack of 10 cubes) =
10 (Tens)
-
Single cube =
1 (Ones)
-
Flat square (10x10 grid) =
100 (Hundreds) — *But none are present here.*
Since we don't see any flat squares (hundreds), all numbers will be less than 100.
---
Now let’s go through each problem:
---
1.
-
1 long rod → 1 × 10 = 10
-
1 single cube → 1 × 1 = 1
✔ Total:
10 + 1 = 11
👉
Answer: 11
---
2.
-
3 long rods → 3 × 10 = 30
-
5 single cubes → 5 × 1 = 5
✔ Total:
30 + 5 = 35
👉
Answer: 35
---
3.
-
5 long rods → 5 × 10 = 50
-
4 single cubes → 4 × 1 = 4
✔ Total:
50 + 4 = 54
👉
Answer: 54
---
4.
-
2 long rods → 2 × 10 = 20
-
8 single cubes → 8 × 1 = 8
✔ Total:
20 + 8 = 28
👉
Answer: 28
---
5.
-
7 long rods → 7 × 10 = 70
-
6 single cubes → 6 × 1 = 6
✔ Total:
70 + 6 = 76
👉
Answer: 76
---
6.
-
4 long rods → 4 × 10 = 40
-
9 single cubes → 9 × 1 = 9
✔ Total:
40 + 9 = 49
👉
Answer: 49
---
✔ Final Answers:
1.
11
2.
35
3.
54
4.
28
5.
76
6.
49

📝 Summary:
We count:
- The number of
tens rods → multiply by 10
- The number of
ones cubes → multiply by 1
- Add them together to get the total number.
This helps students understand place value using visual models.
