How to Teach Past Simple with a Thomas Edison Biography — A2 ESL Lesson Idea
Why a biography lesson lands at A2
Past simple is the single most useful tense for A2 learners, but textbooks often introduce it in flat, decontextualized drills:
Yesterday I (go) to the supermarket.
A biography flips the lens. The same verb forms now carry meaning that students care about — a real person, a real century, a real invention they use every day. And because the text is finite (≈100 words), every past-simple verb is on display in one place, ready to be sorted, drilled, and reused.
This works particularly well as the first lesson of a Famous Inventors unit, where each subsequent class can layer on a new past-simple feature:
- Lesson 1 — Edison → affirmative + Wh-questions (this lesson)
- Lesson 2 — Marie Curie → past simple negative
- Lesson 3 — Steve Jobs → past simple Yes/No questions + time markers
The lesson at a glance
- Level: CEFR A2 — Elementary (ACTFL Novice High)
- Length: 30–45 min
- Skill focus: Reading + Speaking, grammar-led
- Target language: Past simple — affirmative + Wh-questions; regular + irregular
- Stage budget: Warm-up (5) → Presentation (10) → Controlled (12) → Free (10) → Wrap-up (4) = 41 min
The reading passage — steal this
This is the exact 100-word passage to use. It has 11 past-simple verbs spanning regular (loved, worked, invented, called, died, changed) and irregular (was, built, made, had). Read it twice — once at natural pace, once with pauses so students can underline as they go.
The Wizard of Menlo Park
Thomas Edison was a famous American inventor. He was born in Milan, Ohio, in 1847. When he was young, he loved books and small experiments. He worked at many small jobs. In 1876, he built a big laboratory in New Jersey. There, he and his team invented many things. He made the first practical light bulb in 1879. He also invented the phonograph and the motion picture camera. He had more than 1,000 patents. People called him "The Wizard of Menlo Park." Edison died in 1931. His inventions changed the world.
Three teaching moves that make it stick
1. Color-code regular vs irregular
After the second read, draw two columns on the board — Regular and Irregular — and elicit verbs from the class. Color-code regular endings (-ed in red) so students physically see the pattern. This single move solves the #1 A2 error: dropping -ed on regular verbs.
2. Drill the three -ed sounds
The -ed ending is pronounced three ways: /t/, /d/, /ɪd/. Pick one verb of each type and drill chorally:
- worked /wɜːrkt/ — /t/ after voiceless sounds
- called /kɔːld/ — /d/ after voiced sounds
- invented /ɪnˈvɛntɪd/ — /ɪd/ after /t/ or /d/
Korean, Chinese, Vietnamese, and Thai L1 learners especially benefit because their L1s don't have final stop releases — they'll drop the -ed by default unless drilled.
3. Make the free practice transferable
Don't stop at Edison. In the free-practice stage, students interview a partner about any famous person they choose — often a singer, athlete, or scientist from their own country. The grammar transfers; the engagement skyrockets.
Real classroom examples: students have interviewed each other about 장영실 (Jang Yeong-sil) in Korea, 蔡伦 (Cai Lun) in China, 豊田佐吉 (Toyoda Sakichi) in Japan, and Morris Chang in Taiwan.
Anticipated learner problems
A few errors will show up no matter how clean your presentation is:
- "He invent the light bulb." — dropped -ed. Color-code and silently tap the missing ending.
- "When did he invented it?" — double past-marking. Drill: after did, use the BASE verb.
- "He become famous." — using the present form of an irregular. Pre-teach a 10-verb irregular list.

What about cultural context?
Edison is well-known across East and Southeast Asian curricula, but recognition isn't even:
- China · Korea · Japan · Taiwan — heavy textbook coverage; students often know multiple inventions by name.
- Vietnam · Thailand — less detailed coverage; lead with the visual warm-up to bridge.
Keep the biography factual at A2 (born, worked, invented, died). Save the Tesla rivalry and the employee-credit conversation for stronger classes — these are advanced themes that A2 learners can't yet discuss in English.
Wrap-up + next lesson
End with a tight exit ticket: each student writes one true sentence about Edison and one about their chosen person, both in past simple. Cold-call three students, get a class thumbs-up / thumbs-sideways, and address the top error you saw during pair practice.
Then preview Lesson 2: "Marie Curie didn't invent the light bulb. What did she do?" — and you've planted the seed for the past simple negative.
FAQ
How long does this take?
41 minutes with the stage budget above. Cut the free-practice share to fit a 30-minute slot, or extend with the project-based capstone for a 60-minute class.
Is this for young learners or adults?
Both. The passage is age-neutral. For young learners, pre-teach the vocab with flashcards; for adults, lean into the Why and How questions during the pair interview.
Can I use this with mixed levels?
Yes — the premium pack includes Lower-level, Higher-level, and Mixed-class worksheet versions so you can run the same lesson across an ability spread.
What if my students already know past simple affirmative?
Push them to the Higher-level worksheet and require Why and How questions in the pair interview. Then jump ahead to Lesson 2 to introduce the negative.
