In standards 5.NBT.7, the last part of the standard states, "relate the strategy to a written method." What does "written method" mean? In the standard before 5.NBT.6 is clear by stating, "illustrate and explain the calculation by using equations, rectangular arrays, and/or area models." So, does "written method" mean to explain why you chose a particular strategy?
Thank you.

      Written method would mean "labeling" the strategy (model, picture, cubes, etc.) with numbers, to show numerically what the mathematical strategy, or thinking, was. This is a bridge between a strategy or model, and a mathematical procedure.
