Treasure Hunt!

For the past few maths classes we have bee learning about cryptography and how to use it.  Cryptography is an art of writing and solving codes. lets say you have a message that you want to put into code, you first encrypt the message and then decrypt the code if you wish to find out what the message reads. 

Ms. O'B aloud us watch the National Treasure as part of our study on cryptography. everyone really enjoyed the film and it showed us how cryptorgraphy can be used in lots of different situations.
