Introduction

(5 minutes)
Multiplication: Fraction of a Whole
  • Hook students with a scenario: "My favorite TV show is 27 minutes long. Usually I watch it on Friday evenings, but last Friday I fell asleep after watching only ⅓ of the show. I want to finish watching it, but I need to figure out how many minutes I’ve already watched so I can start in the right place."
  • Tell students that in order to figure out how many minutes were watched, we will have to find one-third of 27. So today, we are going to learn how to find fractions of a whole number.

Beginning

  • Provide a translation of the introductory scenario in students' home language (L1) if possible.

Intermediate

  • Define any unknown terms in student-friendly terms in L1 and English (L2), such as "fraction," "improper fraction," "repeated addition," "bar model," "whole number," "numerator" and "denominator."
  • Have students talk to a partner about a time they didn't finish watching a TV show.
