Encourage children to write a word or letter then watch it disappear and reappear before their very eyes.
Materials
- Tacks
- Cardstock
- Scissors
Framing
Write secret message that only you and the people who know how to decipher them can read.
Instructions
- Ask children to cut out the template and use a tack to fasten disks together.
- To “encode” or create a code, ask one child to think of a secret message.
- He/she should turn the small ring to find the first letter of their secret word, inside the rectangle cut-out. Now, instead of writing down this letter, they should write down the letter on the small ring.
- He/she continues until their message is complete.
Modify
- The template will work best on cardstock, or glued to cardboard.
Safety
- There are no foreseeable safety concerns for this activity.
Wrap-up
Participants can invite someone to decode their message, by finding the code letter on the inside ring, and the correct letter in the rectangle.
