Learning journey

Your child is developing advanced problem-solving skills, learning to choose the best mathematical tools and methods for complex problems, and communicating their mathematical reasoning clearly.

Evidence of understanding

  • Break a three-step problem involving unit conversion and multiplication into sub-problems and solve systematically
  • Estimate 4,832 × 7 as roughly 5,000 × 7 = 35,000 to check a calculated answer of 33,824
  • Identify that a percentage answer over 100% doesn't make sense in context

Assessment prompt

When Complex Multi-Step Problems faces a complex multi-step maths problem involving percentages, large numbers, or fractions, do they pause to identify what's known, estimate an answer, and then check their final result makes sense?
