Lesson plan

Goal

Teach (10 min)

  • Some are adding and some are taking away, so look at the sign first.
  • + puts together and makes more. − takes away and leaves fewer.
  • 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.mixFacts?lesson=2-facts&at=2
