In maths we are doing cryptography. This means we can cipher and decipher messages that are mixed up or in codes. We watched the movie "National Treasure" which is all about deciphering clues and codes.
It is really interesting learning about all of this and there is a lot more involved than we first thought. There is a lot of different ways to decipher a code and we have to learn about a lot of them. It is fun to do something in maths outside of the curriculum and something new and fun!
