"Guess Who?" Chatbot

Victoria, Diana, Huyen

Lesson Aims

• Written Reception (A2 level): “Can understand short, simple texts containing the highest frequency vocabulary, including a proportion of shared international vocabulary items.”

• Overall Written Production (A2 level): “Can write a series of simple phrases and sentences linked with simple connectors like ‘and,’ ‘but’ and ‘because’.” Specifically, this task aims to create competency in writing question structure. 

• Grammatical Accuracy (A2 level): “Uses some simple structures correctly, but still systematically makes basic mistakes – for example tends to mix up tenses and forget to mark agreement; nevertheless, it is usually clear what he/she is trying to say.” 

Learning objectives (SWBATs)

Students will be able to :

• write yes/no questions using the Present Simple (do/does) the verb be (am/is/are) and modal verb ( can) , showing control of basic question structure.

• distinguish between using do/does and am/is/are and can to ask correct yes/no questions.

• use correct word order, auxiliaries, and target vocabulary (descriptive adjectives) when forming yes/no questions.

• sustain a short information-exchange game by combining yes/no questions and answers until they identify the correct character.

• collaborate with classmates, taking turns while working on the guessing game in pairs or small groups.

Preparation for the app task cycle

Preparation Steps (Before Lesson)

• Teacher: explore EduCafe features, how to set up the “Guess Who” chatbot, prepares the “Guess Who” character database (e.g., famous people, cartoon characters), test sample interactions, and identify possible technical issues.

• Ensure questions students can ask are suitable and scaffolded for their level.

• Estimated time: Teacher prep: 30–40 minutes; Students: 5–10 minutes in class.

In-Class Preparation

• Students scan the QR code to access the chatbot.

• Teacher models one quick “Guess Who” round with the chatbot so students see how to ask questions and narrow down options.

• Estimated time: 10 minutes.

Materials

• Link to the app: EduCafe 

• Handouts

  • Students will be given a handout with basic, descriptive, vocabulary of people, places, and things that a standard A2 learner would have in their textbook. 

• Equipment

  • The instructor will need a computer. 

  • A projector is needed to show the game on the board so that other students can see the game in action. 

  • Students need a smartphone to interact with the chatbot and type their questions. 

The task cycle

[2 min] Introduction

Passing out vocabulary list to students (this vocabulary has already been taught to a target A2 learner), introducing the game and how the ChatBot works.

[10 min] Play Game

Students will work in groups to brainstorm questions to ask the ChatBot about their given target. They take turns typing questions to the ChatBot. The goal is to guess the target correctly before other groups (optional competitive element).

[8-10 min] Post-task: Assessment

• Each group shares how they identified the target (e.g., “We asked if it were a certain color, then if it could swim, then guessed…”).

Language Focus

• Teacher highlights good examples of student questions.

• Quick correction of common errors (e.g., “You are…?” → “Are you…?”).
