Symbol cipher

Every letter is a little picture. A treasure-hunt note that even new readers want to crack.

When to use it

The first clue of a playground treasure hunt, for a class that is just starting to read. A code to crack at a birthday party or a scout evening. A phonics lesson where decoding the note is the reading practice.

What makes it this

Built on the Cryptogram generator with these changed. Everything else is the default.

  1. Only show letters that occur

    The key leaves out letters the sentence never uses.

  2. Letters given for free

    Characters left unencrypted, as a way in.

Treasure hunt: the picture code

A treasure-hunt clue written in pictures: every letter of the note has been swapped for a drawing, and working out which drawing is which letter tells you where to go next. The vowels are filled in already, to give you a way in.

Why the example is built this way

  1. A short note built from few letters.

    Every different letter needs its own picture. Two short instructions that reuse the same ten letters mean ten drawings, so reword before you add an eleventh.

  2. Pictures that differ in outline and colour.

    Symbols are drawn small on the board. A compass, a ship's wheel and a life ring would all read as circles, so pick shapes that can't be confused.

  3. The vowels are given as the way in.

    Young readers start from words whose shape they can already sound out. Only show letters that occur then leaves one letter chip for each picture still to name.
