⏰ Explorers: The Empty Classroom Mystery
A fully interactive A2.1 Kids reading lesson from the Explorer Club 'Was/Were' unit. Students become detectives and solve a short mystery by tracking past-state clues (was, were, wasn't, weren't). Part 2 is a reading-skill focus: how clues hide in was/were (one vs many), how positive, negative and question clues each help, and a tips panel (underline every was/were, wasn't/weren't means NOT there, ask who/where/when, read it twice). Ten mystery words (mystery, clue, empty, detective, note, board, missing, solve, corridor, garden) come with kid-friendly definitions and examples, and six get review flashcards. The reading, 'The Empty Classroom' (about 120 words), is a warm mystery packed with was/were clues and hover-tooltip vocabulary, with a richer eight-tooltip glossed text and three reading-comprehension quiz questions. Practice offers 8 clue-based fill-in-the-blanks (was/were/wasn't/weren't plus two lesson words) with live validation, hints and a score. Speaking has a solve-it-together retell with five prompts and a five-line model dialogue; the writing task is a 25-45 word retell of the solution with a four-point checklist and live word counter with auto-save. An 8-question quiz (five grammar, three reading-comprehension) closes the lesson with a progress bar, per-question explanations, a conic-gradient result circle and localStorage persistence.

Key Vocabulary
Grammar Points
- Reading clues: was = one person/thing in the past; were = many
- Negative clues: wasn't (was not) and weren't (were not) show what was NOT there
- Question clues: Where were the children? — verb before subject
- Positive clue: The bags were on the chairs (they weren't at home)
- Reading strategy: underline every was/were and read the text twice
- A negative clue is often the biggest clue in a mystery
