Psst! We’ve got a secret message to share with you. CBBC’s Ben Shires and extra special guest Olive are here to reveal all in your Family Mission briefing.


Oh no! Ben forgot the message, didn’t he? Luckily Olive knows how forgetful Ben can be and got in touch with the humans at IWM to cleverly hide the message amongst these mathematical puzzles. Are you ready to decipher the message in our mathematical menagerie? You’ll find everything you need below, including the code breaking key. Good luck!

Code Breaking Key

Have you solved all the puzzles? Now it’s time to decipher the message. Use the code breaking key with the numbers from your answers in the order that you found them to reveal the message!
