📏 Explorers: Bigger & Smaller

A fully interactive A2 Kids grammar lesson that opens the Comparing unit with short-adjective comparatives. Students begin with four warm-up questions about who is taller, bigger, faster and older, then study the language in two clear blocks: The -er + than Pattern (add -er to a short adjective and always follow with 'than': an elephant is bigger than a mouse, Leo is taller than Mia, a cheetah is faster than a dog) and a spelling-rules table (most adjectives add -er; words ending in -e add -r; short vowel + consonant doubles the consonant like big to bigger; words ending in -y change to -ier like happy to happier). Ten key comparatives (bigger, smaller, taller, faster, slower, older, younger, heavier, longer, than) appear in a scrollable table with kid-friendly definitions and examples, and six get detailed review flashcards. The reading is a magazine-style Field Report — a Measuring Day starring Team Compass (Zeynep, Leo, Mia, Kofi) that compares people, pets and animals with -er + than in natural context, with key words highlighted on hover. Practice includes 8 contextualised fill-in-the-blank questions (bigger, than, taller, older, smaller, heavier, longer, slower) with live green/red validation, hints and a running score; a speaking Compare Battle with five prompts and a model partner dialogue; a guided 25-45 word writing task with a four-point checklist and a live word counter with auto-save; and a full 8-question multiple-choice quiz mixing comparative forms, spelling rules and two reading-comprehension questions, with a progress bar, per-question explanations, a conic-gradient result circle with tiered feedback, and localStorage persistence.
