What mastery looks like

  • A country's population is 8,274,500 — round to the nearest million for a headline
  • Order the depths of three ocean trenches given in metres including negative values
  • Estimate the total attendance at three events by rounding each to the nearest 100,000

Check your understanding

If Numbers to Ten Million reads that the distance to the Moon is about 384,400 km, can they round it to the nearest 10,000 km and say whether it's closer to 380,000 or 390,000?
