Introduction

(5 minutes)
  • Lead the students in a quick brainstorm of events that have starting and ending times (e.g. school schedule, sports events, airplane flights, etc.).
  • Tell the students that they are going to be learning how to calculate elapsed time, which is the amount of time that passes between two different times.

Beginning:

  • Have students brainstorm with a supportive peer or one with the same home language (L1), if possible.
  • Allow students to share their ideas in their L1.

Intermediate: Provide a sentence frame to support student sharing, such as " ________ has a start and end time."
