Code Breaking

Saturday, 05 May 2012 | 0 Comments

I recently received an email from the AAMT:

National Mathematics Day is Friday 18 May and looks at codes and code-breaking — to celebrate the centenary of the birth of Alan Turing.

The AAMT have a number of code-breaking exercises on their web-site: National Mathematics Day 2012.
Which reminded me to share the file below. I made this earlier in the year for a Year 7 enrichment maths program. The interactive Excel file contains six code-breaking activities.
