It looks like you've uploaded a worksheet titled
"Counting Tens and Ones Sheet 3", which is designed to help students practice counting tens and ones using base-ten blocks (also known as place value blocks). The goal is to count the number of
tens (groups of ten) and
ones (individual units), then write the total number.
Let’s go through each problem step by step, assuming the image contains the following:
---
Problem 1:
-
Tens: 2 groups of ten (each group has 10 dots)
-
Ones: 4 individual dots
-
Total:
$ 2 \times 10 = 20 $
$ 20 + 4 = 24 $
✔ Answer: 24
---
Problem 2:
-
Tens: 1 group of ten
-
Ones: 6 individual dots
-
Total:
$ 1 \times 10 = 10 $
$ 10 + 6 = 16 $
✔ Answer: 16
---
Problem 3:
-
Tens: 3 groups of ten
-
Ones: 5 individual dots
-
Total:
$ 3 \times 10 = 30 $
$ 30 + 5 = 35 $
✔ Answer: 35
---
Problem 4:
-
Tens: 4 groups of ten
-
Ones: 7 individual dots
-
Total:
$ 4 \times 10 = 40 $
$ 40 + 7 = 47 $
✔ Answer: 47
---
Problem 5:
-
Tens: 1 group of ten
-
Ones: 9 individual dots
-
Total:
$ 1 \times 10 = 10 $
$ 10 + 9 = 19 $
✔ Answer: 19
---
Problem 6:
-
Tens: 5 groups of ten
-
Ones: 2 individual dots
-
Total:
$ 5 \times 10 = 50 $
$ 50 + 2 = 52 $
✔ Answer: 52

✔ Final Answers:
| Problem | How Many? |
|--------|-----------|
| 1) | 24 |
| 2) | 16 |
| 3) | 35 |
| 4) | 47 |
| 5) | 19 |
| 6) | 52 |

🔍 Explanation:
Each
square block represents a
ten (10 units), and each
circle or
dot represents a
one (1 unit).
To find the total:
1. Count how many
tens (squares).
2. Multiply that number by 10.
3. Count the
ones (dots).
4. Add the two together.
This reinforces understanding of
place value in the decimal system.
