Code Cracker — Break the Secret Cipher
Child deciphers a secret message encoded with a simple letter substitution cipher. The agent guides the parent to create the cipher and observe the child's pattern recognition, systematic approach, hypothesis testing, and persistence with abstract problems. This activity reveals logical reasoning, abstract thinking, and the child's approach to problems that require patient, iterative solving.
Free to do together whenever you like.
What you'll need
Parent writes a short message (4-6 common words, all capitals) and encodes it with a Caesar cipher shift of +3 (A->D, B->E, etc.). Write the coded message clearly on paper with spaces between words. Have a second piece of paper and pencil ready for the child to work on. Write out the full alphabet on a separate piece of paper as a reference. For easier difficulty, include one given letter (e.g., write 'D=A' as a starter clue). Have a backup simpler message ready in case the first is too hard.
How it works
