Hi Catter! Thanks for taking the trouble to leave such a positive review. I am so glad that you and your students had fun with this activity!

Hi, Thanks for posting a review. I’m glad you are having fun so far. For Clue 3, remember to do (Across, Up) for each coordinate pair. Thus for (2, 4) you should find the letter I. For Clue 4, you just have to find the correct way to read the message. The message itself is not in code. I hope that helps! Maths126

Also, if you are stuck with any clue, please see the Answers provided. Hope that helps!

Delighted you found it! Thank you, too, for taking the trouble to leave a positive review. It means a lot.

Wow! So pleased to hear that your Maths Club had such fun with this. I know that since I originally posted this back in 2009 (!) there have been many similar ones created, so if your students have got the 'code-breaking bug' do get them to try others - or even write their own!

Thanks for the fantastic review!
