Lesson plan

Goal

  • Students can do this: equivalent fractions in simple cases (½ = 2/4) with models.

Teach (10 min)

  • Equal fractions land on the same spot on the number line.
  • 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/numsense.g3_fracLine?lesson=3-numsense-fracline-1&at=3
