Lesson Overview

The apple doesn’t fall far from the tree! In this lesson, students will discuss appearances and relationships. This lesson features a video of a TV show host who challenges his audience members to guess the affiliation of different people on the street based on their looks. Students will learn and practice modals of deduction and vocabulary relating to this topic. The lesson includes plenty of engaging discussion activities and worksheets that have been developed for adult and teenage learners.

Lesson Objectives

  • Grammar: Learners will explore the use of modals of deduction (must, might, can’t) to express certainty, possibility, and impossibility about affiliations based on appearances. Through exercises and video interaction, students will practice constructing sentences to make guesses about relationships and states of being, enhancing their understanding of modal verb usage in context.

  • Listening: Students will develop their listening comprehension skills by engaging with a video featuring street interviews. They'll listen for cues and specific details to infer relationships between people (couples, siblings, or strangers). This activity aims to sharpen their ability to gather information and deduce relationships from spoken English in real-life scenarios.

  • Speaking: Participants will engage in discussion activities, sharing their thoughts on appearances, relationships, and the use of modals of deduction. They will practice speaking in structured scenarios, such as describing someone's appearance or discussing the likelihood of certain relationships, thereby improving their fluency and confidence in conversational English.

  • Vocabulary: The lesson introduces vocabulary related to appearances (e.g., "attractive," "slim," "bald," "chubby") and relationships ("siblings," "strangers," "couple"). Students will learn and apply new words in discussions, enhancing their ability to describe people and articulate observations about them.

  • Homework: In this section, students are tasked with reading sentences and determining their truthfulness. They must write "T" if the statement is true and "F" if it is false, focusing on vocabulary related to appearances and relationships.


Watch random people being interviewed on the street to see if you can guess who is who. Are they a couple, siblings, or strangers? Sometimes it is not easy to tell!
