Introduction

  • Ask students if their families are ever late to gatherings or events.
  • Call on a few students to share family stories.
  • Ask students to think about how you can plan to be on time - take suggestions (i.e. plan ahead, prepare things the night before, leave earlier, etc.).
  • Tell students that if they learn to count time backwards, they can use that skill to plan a timely arrival.

Beginning

  • Pair students with a supportive peer to share stories and suggestions.
  • Allow them to use their home language (L1) or English as they share.

Intermediate

  • Provide sentence starters for discussion, such as "We were late when ________." and "You can plan to be on time by ________."
