This spreadsheet puzzle leads pupils through a series of interactive screens in which they need to find missing numbers in a series of Fibonacci-style sequences, known as 'Fibs and truths&'. As the puzzle progresses the algebraic demands become greater, giving pupils the opportunity to access many objectives. The teacher has the opportunity to differentiate the numbers within the sequence, and there is an opportunity to try an extension sequence.

    Quite challenging but a brilliant way of showing that algebra is a useful way of solving certain problems. Could easily take a lesson and the discussions involved will be worth while.
