📏 Explorers: Which Is Faster?

A fully interactive A2.1 Kids grammar lesson from the Explorer Club world that teaches children to ask comparison questions and justify their answers. After four warm-up compare questions, students study three language blocks: asking 'Which is …er?' with short adjectives (faster, bigger, stronger), asking 'Which is more …?' with long adjectives plus the special forms better/worse, and answering with 'because' to give a reason (a four-row question-and-reason table). Ten key words (compare, which, because, reason, faster, slower, stronger, heavier, lighter, taller) appear in a scrollable table with kid-friendly definitions and examples, and six get review flashcards. The reading is a magazine-style 'Quiz Night at Base Camp' in which Kofi hosts and Team Compass asks 'Which is…?' questions and answers with 'because', with key words highlighted on hover. Practice includes eight contextualised fill-in-the-blank items (comparatives, than, or, because, which, more) with live green/red feedback, hints and a running score; a speaking section where partners host their own compare-quiz using a model dialogue; a guided 25–45 word writing task (three 'Which is…?' questions answered with because) with a four-point checklist and live word counter with auto-save; and a full eight-question multiple-choice quiz mixing comparison grammar with two reading-comprehension questions, complete with a progress bar, per-question explanations, a conic-gradient result circle and localStorage persistence.
