I set up an Easter egg hunt every year and each time the kids find the eggs within five minutes, so this year I made it a little harder by asking the children to crack a code to tell them where the next egg would be.
I made a separate card for each egg using a different code to write the clue.
Examples of Codes
Replace each letter with a number corresponding to its place in the alphabet.
Reverse the Alphabet ( Z becomes A, A becomes Z etc )
Move each letter one along ( A becomes B )
Move each letter 2 places along ( A becomes C )
Write in invisible ink
Write in white crayon on white paper so the children have to find a way to reveal the clue ( colour over the writing with a different colour crayon )
Replace each letter with a symbol
Can you think of any more codes?
This activity is a lot of fun and great for improving logic skills.
