Today's Activity - Codebreakers!

Today's code is a different kind of code than last time.  If you remember, last time we did a substitution code where each letter was used to indicate a different letter.  This time, each letter will be replaced with a symbol.

To create your code key, first draw 3 tic-tac-toe boards.  Leave the first one plain, but in he second one, make 1 dot in each section (for the first 2 rows, you will put it on the bottom of the section, on the bottom row, you need to put it at the top of the box since the bottom is open.  In the third tic-tac-toe board, you will put 2 dots in each space.

Next, you will fill in the letters of the alphabet, starting in the plain box.  Go across the top row, then the middle, then the bottom, and then move on to the next tic-tac-toe board.

To use the code, you make the shape of your box including the dots if there are any.  Here is an example of some letters:

On this card, I have written some names in code.  Reply when you've figured out what the names are, and start using the code with your friends!
