About This Practice

Rounding is the everyday way to find approximate numbers: keep a chosen place, then look at the next digit — 0 to 4 rounds down, 5 to 9 rounds up. Pick the place to keep and watch a large number get rounded step by step.

How to Play

  1. Read the large number on screen, digit by digit.
  2. Choose which place to round to (ten thousands, hundred millions…).
  3. Look at the digit just after it: is it 0–4 or 5–9?
  4. 0–4 drops the tail; 5–9 bumps the kept digit up by one first.
  5. Write the approximate number and connect the original with it using “≈”.
