You don’t need a screen, expensive software, or even a computer to learn the basics of coding!
This Halloween, trade the spooky stories for some top-secret spy work. With our free “Create a Code” printable activity, kids can step into the shoes of a master cryptographer. Whether they swap letters for numbers, invent bizarre hieroglyphics, or shift the alphabet around like a super spy, they’ll be learning the core logic behind computer science without even realising!
