Code Maker & Breaker

Why

Kids explore alphabet letters, words, and metric measurements with colorful Code Makers and Breakers. Your whole family can create coded messages to decipher.

Steps

1. To make the code maker use Crayola® Scissors to cut a rectangle about 7 cm (3 inches) by 19 cm (7 1/2 inches) from recycled cereal box cardboard.

2. Fold the rectangle in half so the long ends meet. Snip into the fold at 3 cm (1 inch) from each end. Unfold. Cut into each snip to make a 4 cm (1 1/2 inches) opening centered and running parallel to each short end.

3. To make the code breaker, cut a 23 cm (9 inches) by 4 cm (1 1/2 inches) piece of construction paper to fit in the code maker's slots. Trim the sides of the code breaker so it will glide easily when you put it into the code maker.

4. Use Crayola Fine Line Markers to mark 1 cm (1/2 inch) spaces to the right and left of the code maker. Write A through M to the left and N through Z to the right in the spaces.

5. Write the code letters on the code breaker strip so they line up with your code maker alphabet. You can make several codes by sliding the code breaker up so each letter is aligned with a different letter. Write the top two letters that disappear in the new spaces at the bottom. Mark lines on the construction paper strip at the top to show how to line up the letters for the particular message you are sending, then be sure to tell the message's recipient at which line to arrange the code breaker.

Safety Guidelines

Adult supervision is required for any arts & crafts project. Observe children closely and intervene as necessary to prevent potential safety problems and ensure appropriate use of arts and crafts materials. Some craft items, particularly beads and buttons, are potential choking hazards for young children. Avoid use of such small parts with children younger than 3 years. Craft items such as scissors, push pins and chenille sticks may have sharp points or edges. Avoid use of materials with sharp points by children younger than 4 years. Read all manufacturers' safety warnings before using arts and craft supplies.

Scissors—ATTENTION: The cutting edges of scissors are sharp and care should be taken whenever cutting or handling. Blunt-tip scissors should be used only by children 4 years and older. Pointed-tip scissors should be used only by children 6 years and older.

Where & When

"My kids took their Code Makers to a restaurant so they could write secret messages to each other on paper placemats."
Penelope G., mom of kids 7 and 9.

"Older children write messages to each other while younger ones rest. Some kids invent symbols to use instead of letters."
Seema K., family child care provider.


Interesting Info

Cryptography is the study of making and decoding secret messages. When you substitute one letter for another letter you are actually using a cipher. A code is technically a message in which one word substitutes for another word.
