Oh how I loved secret codes when I was a kid. The ability to write a coded letter without anyone but the recipient was just plain fun.
Today on Kids Activities Blog we have 5 secret codes for kids to write their own coded letter.
5 Secret Codes for Kids
1. Reverse the Words
This is a simple code to solve – just read the words backwards! Even though it seems simple once you know the secret, it can be a hard one to figure out when you don’t.
Decode: REMMUS NUF A EVAH
Answer: Have a fun summer
2. Half-Reversed Alphabet
Write out the alphabet letters from A to M then write the letters from N to Z directly below them. Simply exchange the top letters for the bottom letters and vice versa.
Decode: QBT
Answer: DOG
3. Block Cipher
Write the message in a rectangular block, one row at a time – we used 5 letters in each row (alphabet letters in order A-E).
Can you figure out what the KEY is to the block cipher pictured above? Each letter is shifted one place in the second row. You can make any key correspond to the rows making it as simple or complex to figure out. Then write down the letters as they appear in the columns.
Decode: AEC
Answer: BAD
4. Read Every Second Letter
Read every second letter starting at the first letter, and when you finish, start again on the letters you missed.
Decode: WEEVLEIRKYE – STUOMCMAEMRP (mistake made on lower line)
Answer: We Like to camp every summer
5. PigPen
The PigPen code is easier than it looks and is my children’s favorite. First, draw out the two grids below and fill in the letters:
Each letter is represented by the lines around it (or pigpen).
Decode: image above
Answer: I LOVE SUMMER
Write a Coded Letter
We practiced writing our names and silly words before moving to coding whole sentences.
The letters and messages you can write can be fun, but make sure you send along a key so the recipient can figure it all out!
