ESL Activities for C2 (Proficiency) Students
Every ENK game calibrated to CEFR C2, with what it actually asks a C2 student to say — free to browse, no login required.
C2 is the smallest and most demanding tier on the platform — 12 of ENK's 26 apps — reserved for what's genuinely proficiency-level output: analysing complex social, ethical or political scenarios, conveying irony or understatement, shifting register and tone for rhetorical effect, and critiquing a methodology or philosophy rather than just disagreeing with a conclusion. The grammar at this level is closer to written academic register than everyday speech: cleft sentences ("It was... that..."), nominalization, rare modal combinations (might well have, ought to have), and complex discourse markers like "not only... but also."
Most classes will use C2 sparingly — it's calibrated for the small number of students genuinely operating near-native, not as a stretch goal for a B2 class.

Core Language Skills

New Word Order
Jumbled words, one correct sentence. Students physically rearrange AI-generated phrases until the grammar clicks — and their instinct for word order builds.
Teaching guide →
Phrasal Quest
Language through story, not lists. Students pick up phrasal verbs by reading them in context — the way real acquisition actually happens.
Teaching guide →
Grammar Smash
Pick a grammar point, pick a level. Students get a fresh drill instantly — no worksheet, no prep, no repeating the same examples.
Teaching guide →
Sentence Lab
Three random words. Students build one sentence that uses all of them — then defend it to the class.
Teaching guide →
Names, Things, Cities
One letter, every category. Race to empty your hand — name a word in the category you're holding that starts with the round's letter, then dodge Skip and Reverse. And no, "because my aunt said so" doesn't count as a word.
Conversation & Creativity

Dialogue Factory
Two speakers, one scene, no script. Students rehearse an AI-generated dialogue, then progressively lose the lines — until they own it from memory.
Teaching guide →
Say Mean Quotes
A quote appears. Students say what it means, argue whether it's true, and explain why anyone today should still care about it.
Teaching guide →
Argumentation & Debate

BubbleTalk
A topic, some keywords, no full sentences written down. Students deliver a structured presentation using only bubble prompts as scaffolding.
Teaching guide →
You're Wrong
A statement. Two sides. No neutral ground. Students pick a position and defend it — then the class tries to tear it apart.
Teaching guide →
Class Clash
A structured debate, scored in real time. Teams argue, rebut, and face cross-examination — the class votes on who argued best.
Teaching guide →
Mock Trial
A classroom courtroom, a unique case. Students play prosecutors, defenders, and witnesses — and the class delivers a live verdict.
Teaching guide →
Persuasion Arena
AI generates both sides of a debate. Two teams argue assigned positions — then face cross-examination from the opposing bench.
