Introduction

(5 minutes)
Modeling Division Using Number Lines
  • Show the following expression to your students: 12 ÷ 5.
  • Have them think, pair, and share how this expression is related to multiplication.
  • Have students share with the whole class. Ask students to draw connections of how this expression can be rewritten as an improper fraction: 12/5.
  • Further note to your class that since 12/5 = 12 x 1/12, it follows that 12 ÷ 5 = 12 x 1/12.
  • Answer any clarifying questions and announce that this translation is central to today’s lesson.
