If you’ve ever run a ‘treasure hunt’ activity before, then you will be familiar with the concept. However, the principle is to place the sheets around the room and then students begin at a sheet, writing down the sheet number, work out the answer to the question and find which other sheet has that answer at the top and then write down the sheet number. So on and so forth. This will create a loop until they get back to where they started. A nice way to revise or consolidate the topic of functions in maths. It covers the key areas of function notation, domain and range, inverse functions and composite functions.
