“When your child 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?”
Full guide and materials
- Activity. Make sense of complex multi-step problems involving large numbers, fractions, decimals, and percentages by analysing what is known and unknown, planning multi-step strategies, and evaluating reasonableness through estimation and inverse operations
What to notice. 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
