⭐ Builders: The Experience Exchange

A fully interactive B1.1 Builders' Studio task lesson that closes the Present Perfect module by putting the grammar to work live: a speed-exchange event where students collect classmates' most surprising experiences and report the top three to the class. Students begin with four warm-up questions about surprising experiences and why 'I have' becomes 'she has' in a report, then study a three-stage Task Toolkit: Stage 1 is the exchange cycle (Have you ever...? then react, then a past-simple follow-up, then note it) run at speed; Stage 2 teaches reporting in the third person, turning 'I have been' into 'she has been / she's been' with an explicit warning against 'She have been'; Stage 3 is a top-3 report frame table with four bricks (opener, perfect statement, past detail, why it's surprising). Ten key words (exchange, surprising, discover, report, classmate, rotate, common, unique, memory, impressive) appear in a scrollable table with full B1 definitions and examples, six as review flashcards. The reading, 'Exchange Day at the Studio', models the whole task: Marco, Priya, Sam and Aylin rotate at the bell, and Aylin delivers a top-3 report that visibly converts 'I have' into 'he/she has' and adds a past detail each time. Practice offers 8 contextualised fill-in-the-blanks (has, participles, past, exchange, discover, rotate) with live green/red validation, hints and a running score; a speaking section with five exchange-and-report prompts and a six-line model showing one exchange plus its report; a guided 40-70 word writing task drafting a top-3 report with a four-point checklist and live word counter with auto-save; and a full 8-question quiz (six on third-person perfect plus past, two on the reading) with a progress bar, per-question explanations, a conic-gradient result circle with tiered feedback, and localStorage persistence.
