Which method will I use? Can I work it out in my head? Can I round the numbers up or down? Can I add, subtract, times or divide by 10 then adjust? Will my single-digit number facts or my times tables help? Do I need to use jottings? Do I need to record it in any way? Is there a resource I can use? Can I work it out using a written method? Shall I use a number line? Will partitioning help? Shall I use the grid method? Shall I use a column method? Is there more than one step? What do I need to remember (e.g. BODMAS)? Do I need a calculator? How am I going to check my answer? Estimation? Use the inverse operation? Re-read the question?
