Clever little activity.
A simple but brilliant idea. Looks easy, but is actually fiendishly complicated to do by trial and error and requires students to think through a strategy.
Update - Macro Guide added. A single page guide to turning on Macros in Excel. Essentially it involves setting the Macro security to Medium (or Low) and then re-starting Excel.
seems good but. seems good but i can't work it, i open it and bits are cut off and won't co-operate, and a message pops up about 'macros'?!? :(
