Math worksheet for kids practicing counting and estimating to the nearest 10.

Problem Analysis:

The worksheet asks the student to count and estimate the number of items in three different categories:
1. Children: Count and estimate the number of children shown.
2. Dots: Count and estimate the number of dots shown.
3. Ducks: Count and estimate the number of ducks shown.

Solution Approach:

For each category, we will:
1. Count the exact number of items.
2. Estimate the number by rounding to the nearest 10.

Step 1: Counting and Estimating Children

#### Count:
- The image shows two rows of children.
- Each row has 10 children.
- Total number of children = \( 10 + 10 = 20 \).

#### Estimate:
- Since the exact count is 20, which is already a multiple of 10, the estimate is also 20.

Answer for Children:
- Count: 20
- Estimate: 20

Step 2: Counting and Estimating Dots

#### Count:
- The image shows three rows of dots.
- The first two rows have 10 dots each.
- The third row has 4 dots.
- Total number of dots = \( 10 + 10 + 4 = 24 \).

#### Estimate:
- To estimate, round 24 to the nearest 10.
- 24 is closer to 20 than to 30.
- Therefore, the estimate is 20.

Answer for Dots:
- Count: 24
- Estimate: 20

Step 3: Counting and Estimating Ducks

#### Count:
- The image shows five rows of ducks.
- Each row has 10 ducks.
- Total number of ducks = \( 10 + 10 + 10 + 10 + 10 = 50 \).

#### Estimate:
- Since the exact count is 50, which is already a multiple of 10, the estimate is also 50.

Answer for Ducks:
- Count: 50
- Estimate: 50

Final Answers:

1. Children:
- Count: 20
- Estimate: 20

2. Dots:
- Count: 24
- Estimate: 20

3. Ducks:
- Count: 50
- Estimate: 50

Boxed Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{Children:} & \text{Count: 20, Estimate: 20} \\
\text{Dots:} & \text{Count: 24, Estimate: 20} \\
\text{Ducks:} & \text{Count: 50, Estimate: 50}
\end{array}
}
