📏 Explorers: Bigger, Faster, Taller

A fully interactive A2 Kids grammar lesson that opens the comparing unit. Students begin with four warm-up questions comparing pencils, animals, friends and vehicles. The language focus has three clear blocks: The -er + than Machine (short adjective + -er + than, with the full sentence frame A is adjective-er than B, correct/careful examples, and a signals panel that models the weak musical pronunciation of than), a Spelling block with a three-row rules table (just add -er for tall/fast/slow/old/young/short/small; double the last letter for big to bigger; -er always partners with than), and Question Power (a four-row table of compare-questions: Who is taller, Kofi or Leo? Which is faster, a bike or a bus? with model answers). Ten key words (the 8 comparatives plus than and compare) appear in a scrollable table with kid-friendly definitions and examples, and six get detailed review flashcards. The reading is a magazine-style Team File (~220 words) about card-battle day: Zeynep compares an elephant and a cat, Leo learns a turtle is slower but older than a cheetah, and the team builds a height and age line-up, with seven tricky words defined in hover tooltips. Practice includes 8 fill-in-the-blank comparisons (bigger, faster, than, slower, younger, shorter, older, smaller) with live green/red validation, hints and a running score; a speaking section mirroring the classroom card battles and line-ups with five prompts and a model battle dialogue; a guided 25-40 word writing task comparing two things, pets or people at home with a four-point checklist (two things, three -er words, than everywhere, double-letter spelling) and a live word counter with auto-save; and a full 8-question multiple-choice quiz (forms, spelling, than vs then, question word order, and two comprehension questions about the card battle story) featuring a progress bar, per-question explanations, a conic-gradient result circle with tiered motivational feedback, and localStorage persistence.
