This is a brand new set of activity cards to unleash the inner
code-breaker in all of us! The cards contain a combination of codes
such as Semaphore and Morse code, as well as historical codes
including the 'Grid code' used in the American Civil War and
Ancient Egyptian hieroglyphics and traditional codes such as number
replacement and alphabet switching codes. Each card contains
information about the code, including a full explanation of how it
works, and fun activities in which readers can use the code. The
cards are wipe clean and the pack includes a special pen with which
to write the answers on the cards, making the pack entirely self
contained and easily portable. The cards are robust and durable,
ensuring repeated use.
