I hope the kids enjoyed working with the pigpen codes last night. You can download the sheet we used last night here. My son made his coded message “THESE ARE ALL EMBARRASSING,” so dad-mission accomplished.
If you want to try out a simpler code that younger kids will grasp, start with a simple letter-number substitution cipher. Each letter is assigned a number in order:
So to code “DO YOUR BEST” would be “4-15 25-15-21-18 2-5-19-20.”
You can create or solve this type of cipher online using this link.
