The problem with most ESL speaking activities is that both students already know the answer. "Discuss your weekend with your partner" - both students know their own weekend, and neither genuinely needs the other's information to complete the task. The conversation is performed, not real.
Information gap activities solve this structurally. Student A has information Student B needs. Student B has information Student A needs. To complete the task, they must actually communicate. That structural necessity produces the kind of natural, purposeful language that teachers spend entire careers trying to engineer.
YapYapGo is a classroom speaking practice tool for ESL and EFL teachers built around structured pair communication. But information gap activities are one of the most versatile formats you can run with no materials at all. Here are 15 that work across levels.Why information gap works so well
The research on information gap activities traces back to Long's Interaction Hypothesis - the idea that acquisition is driven by the "negotiation of meaning" that happens when communication breaks down and speakers work to re-establish understanding. Information gaps create exactly this condition: both students are genuinely uncertain about something, and both must speak to resolve it.
This is different from discussion activities (where students already know their own opinion) or question-answer activities (where one student performs and the other evaluates). In a well-designed information gap, both students are simultaneously producers and receivers of genuinely novel information.
No-materials information gaps
These require nothing except a clear instruction from you.
1. The hidden object
Student A thinks of an object anywhere in the classroom (or in their bag, or at home). Student B asks yes/no questions to identify it in under 20 questions. Then swap roles. Simple, universally accessible, works at A2 and above.
Language focus: question formation, especially yes/no questions with correct auxiliary verbs.2. Directions to an imaginary place
Student A thinks of a place they know well (their home neighbourhood, their old school, their workplace). Student B asks questions and tries to build a mental map. After three minutes, Student B describes what they imagine. Student A confirms or corrects.
Language focus: prepositions of place, spatial vocabulary, giving and following directions.3. My week vs. your week
Student A thinks of a typical day in their week and keeps it in their head. Student B asks specific questions to reconstruct it: "What time do you usually wake up?" "What do you do between 12 and 2?" After three minutes, Student B summarises what they've learned. Student A corrects any errors.
Language focus: present simple for habits, question formation, time expressions.4. The opinion interview
Student A is told (silently, by you) that they hold a specific opinion: "You think social media should be regulated by governments." Student B doesn't know this and must ask questions to figure out Student A's position on a given topic. Only yes/no answers until the position is clear. Then open discussion.
Language focus: indirect questions, hedging, expressing certainty and uncertainty.5. The news story
Student A is told a news story headline (written on a slip of paper): "Mayor bans cars from city centre." Student B doesn't know the headline and asks questions to reconstruct what happened. Student A can only answer questions, not volunteer information.
Language focus: past tense, question formation, news vocabulary.Tool tip: YapYapGo serves discussion questions automatically so you can run the conversation phase without any materials. For the gap-filling phase, a classroom countdown timer visible to the whole class keeps all pairs working at the same pace.
One-card information gaps
These require one written card per pair - worth the two minutes of prep.
6. Describe and draw
Student A has a simple diagram, map, or picture. Student B has a blank piece of paper. Student A describes their picture in words; Student B draws what they hear. No showing until the end. Compare results.
This is one of the most reliable information gap formats ever tested: it forces precise language, generates immediate comprehension feedback, and is genuinely fun when the drawings don't match.
Language focus: spatial vocabulary, shapes, precise description, clarification strategies.7. The missing information table
Create a table with two columns: "Student A knows" and "Student B knows." Student A's column has some cells filled; Student B's column has the rest. They ask each other questions to complete their tables. Classic for B1+.
Example topics: comparing two countries, two historical events, two products.
Language focus: question formation, numbers, comparison language.8. The story sequencing gap
Write six sentences from a story on two cards. Student A gets sentences 1, 3, and 5. Student B gets sentences 2, 4, and 6. Without showing their cards, they reconstruct the full story by reading their sentences aloud and agreeing on the order.
Language focus: narrative sequencing, time connectors, listening for detail.9. The alibi game
A "crime" has been committed at 7pm on Tuesday. Student A is the suspect. Student B is the detective. Student A must construct a plausible alibi (where they were, what they did, who they were with) and stick to it consistently. The detective asks detailed questions to find inconsistencies. Then swap.
Language focus: past simple and past continuous, storytelling under pressure, question formation.10. Spot the difference
A classic: two similar pictures with 10 differences. Students describe their picture to find what's different without showing each other. The constraint that they cannot look at each other's picture forces genuine description.
Language focus: there is/are, spatial vocabulary, hedging ("I think mine has... does yours?").Longer information gap projects
These take 15-20 minutes and work well as the centrepiece of a lesson.
11. The job interview (asymmetric roles)
Student A is a job applicant with a CV in their head (they invent it). Student B is an interviewer with a job description in their head (they invent it). Neither knows the other's information. They conduct a genuine job interview, each working with information the other doesn't have.
Language focus: professional vocabulary, question formation, expressing ability and experience.12. The travel planning gap
Student A wants to travel somewhere and has a budget, a set of preferences, and some constraints (must avoid flying, has 10 days, vegetarian). Student B is a travel agent with three destination options they've been assigned (written on a card). Through conversation, they must find which destination fits best.
Language focus: conditional language, expressing preferences, recommendations.13. The problem-solving pair
Student A has a problem described on a card: "You need to move house in two weeks and you have no car, no money, and three large items of furniture." Student B has three possible resources they can offer (also on a card): "You have a van, a day free next Saturday, and a friend who's a professional mover." Through conversation, they must negotiate a solution.
Language focus: modal verbs, negotiation language, conditional structures.14. The witness and detective
One student witnessed an event (described on a card). The other is a detective who must reconstruct exactly what happened through questioning. The witness can only answer questions - they cannot volunteer information. The detective must piece together the story.
Language focus: past tense, question formation, clarification.15. The product pitch gap
Student A has invented a product (described on a card). Student B is an investor who has specific requirements (also on a card: must be eco-friendly, must solve a real problem, must cost under £50 to make). Student A must pitch their product; Student B must decide whether to invest.
Language focus: persuasive language, product vocabulary, agreeing and disagreeing professionally.Designing your own information gaps
Any information gap activity needs three elements:
A genuine asymmetry: Each student must have something the other doesn't. If both students can see all the information, the gap disappears. A communicative goal: There must be a reason to close the gap - a decision, a drawing, a story, a table to complete. Without a goal, the activity becomes artificial. A constraint on information transfer: Students can't just show each other their cards. The constraint forces language production. "Describe without showing" is the most common constraint and almost always works. YapYapGo handles the question delivery and pair rotation automatically - so you can focus on designing the activity rather than managing logistics. A random student picker is useful for sharing interesting examples. A class timer keeps all pairs on the same schedule. For related ideas, see our post on speed conversation activities.
