Puzzle: Algebraic Thinking Practice with Excel

In this simple math puzzle (created after I saw another teacher use a set of commercially produced cards with the same purpose) learners are given three or four random numbers that can form a true equation, and they have to find the equation as quickly as they can! The spreadsheet provides immediate feedback and a new problem after every attempt. Pairs well with intense music, a little friendly competition in teams and a countdown timer!
