What are secret messages?

A secret message is like hiding a note inside your lunch box so only you and your best friend can read it.

Imagine you and your friend have a special way to write notes that only the two of you understand. You might use a code, like turning every letter into another one, or drawing little pictures instead of words. That’s how secret messages work: they’re like invisible letters that only certain people can see.

When you write a note, it's easy for anyone to read. But if you use a code, like changing "A" into "B," or "Hello" into "24567," then others won’t know what it says, unless they also know the code.

Sometimes people even use things around them to help hide messages, like leaving clues in a drawing, or hiding letters inside another letter. It’s like playing a game of hide-and-seek with words!

People use secret messages when they want to talk without others knowing, like passing notes in class or sending coded letters during a treasure hunt!
