Check understanding

  • Given a three-digit number, state what is 10 more and 10 less
  • Given a three-digit number, state what is 100 more and 100 less
  • Explain the strategy using place-value understanding (e.g. only the tens/hundreds digit changes)
“Can your child quickly work out '10 more than 342' or '100 less than 875' in their head — knowing which digit changes and which stays the same?”
