Fun, educational worksheet where children decode a prayer-related phrase using a number-to-letter cipher.

Problem Description:

The task involves decoding a secret code using a provided "Code Key." Each number corresponds to a letter of the alphabet, and the goal is to fill in the blanks with the correct letters to reveal a hidden phrase. The Code Key maps numbers to letters as follows:

- A1, B2, C3, D4, E5, F6, G7, H8, I9
- J10, K11, L12, M13, N14, O15, P16, Q17, R18
- S19, T20, U21, V22, W23, X24, Y25, Z26

Solution Approach:

1. Understand the Code Key: Each number from 1 to 26 corresponds to a specific letter of the alphabet.
2. Decode Each Number: Replace each number in the given sequences with its corresponding letter using the Code Key.
3. Form Words and Phrases: Once all numbers are replaced, read the resulting sequence of letters to form words and phrases.
4. Identify the Final Phrase: The last sequence of numbers represents the final decoded phrase.
