⛓️ Builders: If This, Then That

A fully interactive B1.1 grammar lesson that opens the First Conditional module of the Builders' Studio. Learners warm up with four future-possibility questions, then study the language in three blocks: the Two-Half Machine (if + present simple joined to will + base for real results), the Comma by Breath (a comma when the if-half comes first, none when the result leads), and Keep the If-Half Real (never 'will' after 'if', with a matched conditions-and-predictions table). Ten B1 words for conditions, results and possibility appear in a scrollable table with full definitions and examples, and six become review flashcards. The reading is a 160-word Weekend File in which Aylin, Marco, Priya and Sam plan a Saturday around the weather, packed with natural first conditionals and hover-tooltip vocabulary. Practice offers eight contextualised fill-in-the-blank items (rains, will, don't, finishes, comma, will, if, probably) with live green/red feedback, hints and a running score. Speaking gives five real-plan prompts and a six-line model dialogue; the writing task is a 40-70 word plan for tomorrow with a four-point checklist and a live word counter with auto-save; and an eight-question quiz mixes first-conditional grammar with two reading-comprehension questions, each with a one-sentence explanation and a saved score.
