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

  1. Ask children to cut out the template and use a tack to fasten disks together.
  2. To “encode” or create a code, ask one child to think of a secret message.
  3. 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.
  4. 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.
