Let's get cracking!

Built by teachers using the latest research in pedagogy, Code Cracking is Barefoot’s adventure into the exciting history of World War Two coding through code cracking, researching and filmmaking. Created for pupils aged 9-11, Code Cracking brings problem-solving skills to life through the power of logical thinking, creativity and teamwork.

Code Cracking is made up of six ‘top secret lessons’ that help pupils to think, work together and have fun. As with everything Barefoot, Code Cracking comes complete with a suite of materials that help teachers and pupils fully engage with this intriguing resource toolkit.

We also have some great prizes to win, so read on to get started with Code Cracking!
