Which planning approach is recommended for a multi‑step word problem to maintain clarity?

• A. Solve first and then check whether the result makes sense.
• B. Begin with the most complex formula you know.
• C. Outline steps first, but skip identifying knowns and unknowns.
• D. Identify knowns and unknowns, outline steps, solve in the simplest sequence.

Answer: (D)

Identifying what you know and what you need to find, then outlining a plan before solving, is the key here. Knowing the knowns and unknowns helps you map all the data and relationships in the problem, so nothing essential is missed. Outlining the steps first gives you a clear path to follow, showing how the pieces fit together and which relationships or formulas to apply. Solving in the simplest sequence keeps the work organized and makes it easy to verify each part—checking units, reasonableness, and how the pieces connect—before moving on. For example, in a travel problem with two legs, you’d first list the knowns (distance and speed for each leg) and the unknown (total time). Then you outline steps: find each leg’s time using time = distance/speed, then add the times to get the total. Solve in that order: compute times, then sum. This structure makes it straightforward to check plausibility and catch any mistakes early. That combination—identify knowns and unknowns, outline steps, and solve in the simplest sequence—provides a clear, reliable path through a multi-step word problem.
