Problem Analysis:
The task involves working with the
3 times table and identifying patterns in a grid. The goal is to:
1. Fill in missing values in the grid.
2. Solve multiplication problems involving the number 3.
3. Count sets of 3 flowers in images.
Let's solve each part step by step.
---
Part 1: Completing the Grid
The grid shows numbers arranged in rows and columns, and we need to identify the pattern. The grid is partially filled, and we can observe that it follows a sequence where each row increases by 1 starting from the first column.
#### Observations:
- The first row starts with 1, 2, 3, 4, 5.
- The second row starts with 6, 7, 8, 9, 10.
- Each subsequent row increases by 5 (e.g., 11, 12, 13, 14, 15).
Using this pattern, we can complete the grid:
| | 1 | 2 | 3 | 4 | 5 |
|---|-----|-----|-----|-----|-----|
| 1 | 1 | 2 | 3 | 4 | 5 |
| 2 | 6 | 7 | 8 | 9 | 10 |
| 3 | 11 | 12 | 13 | 14 | 15 |
| 4 | 16 | 17 | 18 | 19 | 20 |
| 5 | 21 | 22 | 23 | 24 | 25 |
The grid is now fully completed.

Part 2: Solving Multiplication Problems
The task asks us to solve the following multiplication problems:
1.
1 × 3 = ?
- This is straightforward: \( 1 \times 3 = 3 \).
2.
2 × 3 = ?
- This is also straightforward: \( 2 \times 3 = 6 \).
3.
3 × 3 = ?
- This is: \( 3 \times 3 = 9 \).
4.
4 × 3 = ?
- This is: \( 4 \times 3 = 12 \).
5.
5 × 3 = ?
- This is: \( 5 \times 3 = 15 \).
So, the answers are:
\[
1 \times 3 = 3, \quad 2 \times 3 = 6, \quad 3 \times 3 = 9, \quad 4 \times 3 = 12, \quad 5 \times 3 = 15
\]

Part 3: Counting Sets of 3 Flowers
The task provides images of flowers and asks how many sets of 3 flowers are present in each image.
#### Image 1:
- There are 6 flowers in total.
- To find the number of sets of 3, divide the total number of flowers by 3:
\[
6 \div 3 = 2
\]
So, there are
2 sets of 3 flowers.
#### Image 2:
- There are 9 flowers in total.
- To find the number of sets of 3, divide the total number of flowers by 3:
\[
9 \div 3 = 3
\]
So, there are
3 sets of 3 flowers.
#### Image 3:
- There are 12 flowers in total.
- To find the number of sets of 3, divide the total number of flowers by 3:
\[
12 \div 3 = 4
\]
So, there are
4 sets of 3 flowers.

Final Answers:
1. Completed grid:
\[
\begin{array}{c|c|c|c|c|c}
& 1 & 2 & 3 & 4 & 5 \\
\hline
1 & 1 & 2 & 3 & 4 & 5 \\
2 & 6 & 7 & 8 & 9 & 10 \\
3 & 11 & 12 & 13 & 14 & 15 \\
4 & 16 & 17 & 18 & 19 & 20 \\
5 & 21 & 22 & 23 & 24 & 25 \\
\end{array}
\]
2. Multiplication results:
\[
1 \times 3 = 3, \quad 2 \times 3 = 6, \quad 3 \times 3 = 9, \quad 4 \times 3 = 12, \quad 5 \times 3 = 15
\]
3. Number of sets of 3 flowers:
- Image 1:
2 sets
- Image 2:
3 sets
- Image 3:
4 sets
Boxed Final Answer:
\[
\boxed{2, 3, 4}
\]
