Multi-Step Problem Solving

Mathematics · Mathematical Thinking · meta

With teacher support, make sense of multi-step problems involving larger numbers or mixed operations by breaking them into parts, choosing strategies, and checking answers for reasonableness — children at this stage are developing the habit with guidance; independent strategy evaluation comes later

What mastery looks like

  • Break a two-step word problem within 1000 into sub-problems and solve each part
  • Estimate an answer before calculating to set a reasonableness benchmark
  • Check an answer using a different method or inverse operation and revise if needed

Check your understanding

If Multi-Step Problem Solving gets an answer that seems way too big or too small for a maths problem, do they notice and go back to check, even without you pointing it out?
