This resource is based on a selection of 17 questions on trace tables taken from past papers. The first document contains the exam questions, which can be printed for your pupils. The second document is a spreadsheet designed to help the students get the trace tables correct before they fill in the printed document - as they fill in each cell within a trace table, it will stay black if it is correct, but turn red if it is wrong. This means they will be aware of any error as soon as they make it, rather than working through the whole table and only realising at the end that they need to make corrections. The third document is the answers (mark schemes) to the questions.
