🎬 Explorers: Didn't & Did You?

A fully interactive A2.1 Explorer Club grammar lesson that teaches the negative and question forms of the regular past. Students start with four warm-up questions, then study three grammar blocks: The -ed Falls Off (didn't + base verb for negatives, with a past-signal-words panel: yesterday, last night, last week, an hour ago, on Saturday), Did You…? (Did + subject + base verb for questions, plus Yes, I did / No, I didn't short answers), and Watch the Machine (a rules table lining up affirmative, negative, question and short-answer shapes of one verb so only the affirmative keeps -ed). Ten regular verbs (play, watch, cook, walk, talk, help, clean, jump, want, visit) appear with their -ed past and example sentences, and six get review flashcards showing the base-verb reset. The reading, 'A Rainy Saturday', is a magazine-style Team File in which Zeynep, Leo, Mia and Kofi talk about what they did and didn't do, packed with natural didn't and Did you…? and seven hover-tooltip words. Practice has 8 contextualised fill-in-the-blank items (didn't, did, and base verbs) with live green/red validation, hints and a running score; speaking offers five Did you…? prompts plus a Truth-or-Lie game and a six-line Team Compass model dialogue; a guided 25-45 word writing task asks for two things you did/didn't do, a question and a short answer, with a four-point checklist, live word counter and auto-save; and a full 8-question multiple-choice quiz mixes negatives, questions, base-verb discipline and two reading-comprehension questions, with a progress bar, per-question explanations, a conic-gradient result circle and localStorage persistence.
