You are under pressure to break your enemy's code. You know that the letters have been encoded as numbers using:

You have a message coded by the enemy coding machine. Your secret network of spies has found out that the message is part of a nursery rhyme. Your job is to look at the coded text and try to guess what numbers the enemy is using for A and B. Good luck!

Think carefully about what guesses to make for A and B. Look at the coded phrase and think about patterns. There is scratch space below for you to record your ideas. The students who guess the A and B correctly in the shortest amount of time win!
