Lesson plan

Goal

  • Students can do this: ratio language ("3 to 2").

Teach (10 min)

  • A ratio compares two amounts. 3 red beads and 5 blue beads is the ratio 3 : 5, with red named first.
  • "For every 3 red there are 5 blue" says the same thing. The order matters: 5 : 3 is blue to red.
  • 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/ratio6.language?lesson=6-ratio6-language-1&at=6
