🏊 Can You Swim? What Can You Do?

A fully interactive A1 Teens grammar lesson built around abilities — what students can and can't do. Students warm up with four questions about their own skills, then study 'can' for ability through clear formula blocks for affirmative, negative, question, and short-answer forms. Key rules are made explicit: 'can' is the same for every subject (no -s for he/she), it takes the base verb (no 'to'), and 'can't' is the short form of 'cannot'. A visual action-verb grid presents twelve skills with emoji (swim, ride a bike, play guitar, play piano, cook, dance, sing, play football, draw, run fast, climb, skateboard). The reading text is an extended, double-length story (around 525 words) about a school talent show, featuring four students: Diego who can dance, Lucia who can sing, Sam who can do magic, and Priya whose message is 'today you can't, but tomorrow, with practice, you can!' — all rich with can/can't in natural context. Ten key vocabulary items appear in a horizontally-scrollable table with part of speech, A1-friendly definition, and example, while six receive detailed flashcards. Practice includes 8 contextualised fill-in-the-blank questions with hints, live validation, and score tracking; a speaking section where students ask each other 'Can you...?'; a guided 50–70 word writing task with a checklist and live word counter; and a full 8-question multiple-choice quiz featuring a progress bar, per-question explanations, a result circle with motivational feedback, and localStorage persistence.
