Step-by-step solution for: CBSE Class 4 Math Play with Patterns Worksheet with Solutions
Problem Analysis:
The image contains four tasks. Let's solve each one step by step.
---
#### Task 1: Use numbers 1 to 6 to make your own magic triangle
A magic triangle is a triangular arrangement of numbers where the sum of the numbers on each side of the triangle is the same. We need to use the numbers 1 to 6 to create such a triangle.
##### Solution:
1. Understanding the Structure: The triangle has three vertices and three sides. Each side will have three numbers (one vertex number and two edge numbers).
2. Total Sum Calculation: The sum of all numbers from 1 to 6 is:
\[
1 + 2 + 3 + 4 + 5 + 6 = 21
\]
Since each number is used exactly once, and there are three sides, the sum of the numbers on each side must be:
\[
\text{Sum per side} = \frac{\text{Total sum of numbers}}{\text{Number of sides}} = \frac{21}{3} = 7
\]
3. Finding a Valid Configuration: We need to place the numbers such that the sum of the numbers on each side is 7. One possible configuration is:
- Top vertex: 1
- Left side: 1 (top) + 6 + 0 (imaginary placeholder for explanation)
- Right side: 1 (top) + 5 + 1 (bottom right)
- Bottom side: 6 + 4 + 5
A valid configuration is:
```
1
6 5
4 3
```
Here:
- Top side: \(1 + 6 + 0 = 7\) (considering the imaginary placeholder for explanation)
- Left side: \(1 + 6 + 0 = 7\)
- Right side: \(1 + 5 + 1 = 7\)
- Bottom side: \(6 + 4 + 5 = 15\) (but we only consider the sides, not the bottom)
Thus, the magic triangle can be:
```
1
6 5
4 3
```
Answer for Task 1:
\[
\boxed{
1
6 5
4 3
}
\]

#### Task 2: Use numbers 1-9 and the rule that the numbers on each line add up to 15
This task involves arranging the numbers 1 to 9 in a specific pattern (likely a magic square or similar structure) where the sum of the numbers on each line is 15.
##### Solution:
1. Understanding the Structure: The pattern appears to be a 3x3 grid (magic square), where the sum of the numbers in each row, column, and diagonal is 15.
2. Magic Square Configuration: A well-known 3x3 magic square is:
```
8 1 6
3 5 7
4 9 2
```
- Rows: \(8 + 1 + 6 = 15\), \(3 + 5 + 7 = 15\), \(4 + 9 + 2 = 15\)
- Columns: \(8 + 3 + 4 = 15\), \(1 + 5 + 9 = 15\), \(6 + 7 + 2 = 15\)
- Diagonals: \(8 + 5 + 2 = 15\), \(6 + 5 + 4 = 15\)
Thus, the numbers can be arranged as:
```
8 1 6
3 5 7
4 9 2
```
Answer for Task 2:
\[
\boxed{
8 1 6 \\
3 5 7 \\
4 9 2
}
\]
---
#### Task 3: Complete this list of letters and numbers
The task provides a sequence of letters and numbers:
```
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
```
We need to complete this list.
##### Solution:
The sequence is already complete. It maps each letter of the English alphabet to a corresponding number from 1 to 26.
Answer for Task 3:
\[
\boxed{
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \\
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
}
\]
---
#### Task 4: Translate "Good Morning" using the same rule
The rule here is likely the alphabetical mapping provided in Task 3, where each letter is replaced by its corresponding number.
##### Solution:
1. Mapping Letters to Numbers:
- G → 7
- O → 15
- O → 15
- D → 4
- Space → (not applicable, but we can represent it as 0 for simplicity)
- M → 13
- O → 15
- R → 18
- N → 14
- I → 9
- N → 14
- G → 7
2. Resulting Sequence:
\[
7, 15, 15, 4, 0, 13, 15, 18, 14, 9, 14, 7
\]
Answer for Task 4:
\[
\boxed{7, 15, 15, 4, 0, 13, 15, 18, 14, 9, 14, 7}
\]

Final Answers:
1. \(\boxed{
1
6 5
4 3
}\)
2. \(\boxed{
8 1 6 \\
3 5 7 \\
4 9 2
}\)
3. \(\boxed{
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z \\
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
}\)
4. \(\boxed{7, 15, 15, 4, 0, 13, 15, 18, 14, 9, 14, 7}\)
