Lesson plan

Goal

  • Students can do this: round to nearest 10 or 100.

Teach (10 min)

  • Rounding finds the closest ten. 34 is closer to 30 than to 40.
  • Exactly halfway, like 35, rounds up to 40.
  • Work one example on the board while students say each step aloud, then do one together.

Practise (15 min)

  • Students work the printable sheet in pairs, then alone.
  • Or practise it as a game with no sign-up: https://peabody.kids/math/whole.round?lesson=3-round-ten&at=3
