💬 Builders: Agreeing & Disagreeing with Grace

A fully interactive B1.1 Teens grammar-and-speaking lesson that teaches concession and extension moves — how to respond to another person's opinion politely. Students begin with four thoughtful warm-up questions about kind disagreement, then study a three-box Graceful Response Toolkit: Agree & Extend (acknowledge + 'and also / on top of that' + a new point), Disagree with Grace (a concession such as 'I see your point' + 'but / however' + your different view, plus the never-say-'You're wrong' rule), and the Response Recipe table (Acknowledge → Link → Add, with although as a concession word and the golden rule of arguing with the idea, not the person). Ten key words (opinion, agree, disagree, point, reason, however, although, admit, fair, respect) appear in a scrollable table with full B1 definitions and examples, and six become review flashcards. The reading is a Builders' Studio round table starring Priya, Marco, Aylin and Sam debating whether students should choose their own homework, modelling every response phrase in natural context with hover-tooltip vocabulary. Practice includes 8 single-word fill-in-the-blank items (point, true, admit, fair, with, however, but, and) with live green/red validation, hints and a running score; a speaking section with five opinion-ping-pong prompts and a six-line model rally between the cast; a guided 40-70 word writing task (a graceful reply to 'Summer holidays should be longer') with a four-point checklist and a live word counter with auto-save; and a full 8-question multiple-choice quiz mixing the response phrases with two reading-comprehension questions, featuring a progress bar, per-question explanations, a conic-gradient result circle with tiered feedback, and localStorage persistence.
