🔀 Builders: Finished Time vs Life Time

A fully interactive B1.1 grammar lesson that opens the Builders’ Studio Pivot module — the signature skill of the B-band. Learners meet the two time zones that control everything: closed, finished time (yesterday, last night, in 2020, two years ago, when I was seven) which demands the past simple, and open time still connected to now (ever, never, in my life, this week, today, so far, recently, already, yet) which demands the present perfect. Part 2 teaches this in three boxes: Zone 1 vs Zone 2 with formula chips and closed/open examples; a Read-the-Signal rules table pairing each signal with its zone and tense plus a flags-at-a-glance panel; and a Golden Rule box that shows the classic error (I have seen it yesterday) beside its cure (I saw it yesterday) in both directions. Ten key words (finished time, open time, signal word, past simple, present perfect, ago, so far, recently, ever, experience) appear with full B1 definitions and examples, and six get review flashcards. The reading, The Wall of Firsts, stars Aylin, Marco, Priya and Sam sharing life experiences (present perfect) whose details — last month, in 2023, two years ago — always pull back to the past simple, with seven hover-tooltip words. Practice offers eight single-word fill-ins (saw, eaten, ago, have, made, yet, far, did) with live validation, hints and a score; speaking pairs a present-perfect opener with a past-simple detail question and a six-line Aylin-and-Sam model; a 40–70 word writing task asks for one closed-time and one open-time sentence with a four-point checklist and live counter; and an eight-question quiz mixes signal-spotting, tense choice and two reading-comprehension items, with per-question explanations, a result circle and localStorage persistence.
