The Semaphore signalling system uses the position of a pair of hand-held flags to represent letters of the alphabet. Print these Semaphore alphabet cards to help kids learn the alphabet - they can practise on their own or maybe send messages to their friends using flags!

This coded message uses a simple letter transposition code to hide a message for St Patrick's Day. Can the kids work it out?
Crack the code to work out what Oliver has asked Santa to bring him this Christmas. We haven't provided any clues at all, so children will need to think about how they might write a letter to Santa to get them started.
