💼 Explorers: No Need vs No Way

A fully interactive A2.2 Kids grammar lesson that nails the classic obligation confusion: don't have to means 'no need — it is your free choice', while mustn't means 'no way — it is forbidden'. After four warm-up questions about rules and free choices, students study three clear focus blocks: Don't Have To = No Need (don't/doesn't have to for things that are not necessary), Mustn't = No Way (forbidden actions, danger and firm rules) with a spot-the-difference signals panel, and a Two Sentences, Big Difference contrast table. Ten key words (rule, forbidden, allowed, optional, choice, break a rule, dangerous, safe, duty, free) appear in a scrollable table and six get review flashcards. The reading is a magazine-style Team File in which Ranger Ada teaches Team Compass the Night Sky Camp rules — mixing don't-have-to free choices with mustn't safety rules — with seven hover-tooltip words. Practice includes eight contextualised fill-in-the-blank items (don't, doesn't, mustn't and lesson words) with live validation, a speaking section with five prompts and a five-line Team Compass model dialogue, a guided 30-50 word writing task about weekend rules with a four-point checklist and live word counter, and an eight-question quiz with progress bar, per-question explanations, a result circle and localStorage persistence.
