🚦 Explorers: Can I…, Please?

A fully interactive A2.1 Kids grammar lesson from the Explorer Club world that teaches children to ask for permission and respond politely. Students start with four warm-up questions about school rules and polite asking, then study the language in three clear blocks: asking with 'Can I / Can we + base verb?', answering kindly ('Of course!' / 'Yes, you can.' vs 'Sorry, you can't.'), and a 'can vs must' table that separates permission from obligation (must / mustn't). Ten key words (permission, ask, borrow, polite, of course, sorry, must, mustn't, quiet, careful) appear in a scrollable table with kid-friendly definitions and examples, and six get detailed review flashcards. The magazine-style reading follows Team Compass at a Science Park, asking 'Can I…?' at every step and reading a 'mustn't touch' sign, with seven hover-tooltip vocabulary words. Practice includes 8 contextualised fill-in-the-blank questions (Can, can't, must, mustn't, course, and lesson words) with live green/red validation, hints and a running score; a speaking section with five 'Can I…?' prompts and a six-line model dialogue; a guided 25-45 word writing task with a four-point checklist; and an 8-question multiple-choice quiz with a progress bar, per-question explanations, a result circle and localStorage persistence.
