⭐ Builders: Have You Ever...?

A fully interactive B1.1 teens grammar lesson that opens the Perfect module. Students build the present perfect for life experiences: have or has plus the past participle, with no exact time because the time is your whole life until now. Four warm-up questions activate real experiences, then a three-box language focus teaches the form (have/has + participle, short forms 've/'s, negatives with never), Ever & Never (ever in questions, never meaning not-at-any-time, short answers Yes I have / No I haven't), and Participle Bricks (a base-to-participle table for be/been, see/seen, try/tried, eat/eaten, fly/flown, do/done), plus a life-until-now timeline signal panel. Ten key words (ever, never, experience, participle, been, seen, tried, eaten, flown, abroad) come with full B1 definitions and examples, and six get review flashcards. The reading is an Experience Wall with four first-person truths from Aylin, Priya, Marco and Sam, packed with present perfect and eight hover-tooltip words. Practice offers eight single-word fill-ins (participles, have/has, ever/never) with live feedback and hints; speaking is a five-prompt Have-You-Ever circle with a six-line model dialogue; the guided 40-70 word writing task asks for honest have-done and never-done lines with a four-point checklist and live counter; and an eight-question quiz mixes present perfect grammar with two comprehension questions about the Experience Wall, with progress bar, explanations, a result circle and localStorage saving.
