SECRET CODES

Today in library we read Henry and Mudge and the Sneaky Crackers by Cynthia Rylant. Henry buys a spy kit and then he and Mudge begin to spy in the neighborhood. When Henry finds a secret message, he has to use his secret code card to figure it out. We discussed what secret codes are and why they might be used.

Would you like to try writing your name in a code? Use the code below to write your name in code.

Ms. Bradley's name in code is: 13-19. 2-18-1-4-12-5-25

Do you see how it works? Now you try:

My name is_________________________________________________________.

My name in this code is________________________________________________.

One secret code is:

A = 1
B = 2
C = 3
D = 4
E = 5
F= 6
G = 7
H = 8
I = 9
J = 10
K = 11
L = 12
M = 13

N = 14
O = 15
