I can answer questions on today's skill on my own, without help.
I can explain each step and say why it works.
I can check my answer and spot a mistake.

Before and after

Needs first: Summarising

Leads to: Main idea of a short academic text (SAT)

Materials: A short text or extract (one copy each), Highlighters, Question cards, Mini whiteboards, A short model text on the board, Printed student sheet (below).

Warm-up · 4 min

Quick retrieval from earlier learning (Summarising). Students answer on mini whiteboards.
Show answers together and note who needs support in the main task.

Mangrove trees grow along tropical coasts where land meets sea. Their tangled roots trap mud, protecting shores from storms and erosion. The roots also shelter young fish, crabs and shrimp. Yet mangroves are being cut down for farms and resorts faster than many other forests. Which is the best summary? (Crabs live in mangrove roots. / Mangroves protect coasts and shelter sea life but are being destroyed quickly. / Mangroves grow in the tropics. / Resorts are popular with tourists.) → Mangroves protect coasts and shelter sea life but are being destroyed quickly.Prompt: What is the WHOLE text mostly about, not just one part?
The first bicycles had no pedals; riders pushed along with their feet. Later models added pedals to a giant front wheel, which made them fast but dangerous. Eventually, the safety bicycle, with two equal wheels and a chain, became the design we use today. Which is the best summary? (Early bicycles were dangerous. / Bicycles have two wheels. / Riders pushed with their feet. / Bicycles developed over time from pedal-less models to the safer chain-driven design used today.) → Bicycles developed over time from pedal-less models to the safer chain-driven design used today.Prompt: What is the WHOLE text mostly about, not just one part?
In 2019, pupils at Hill School noticed that the stream behind the school was full of plastic. They organised monthly clean-ups, wrote to the council, and persuaded local shops to stop using plastic bags. Within a year, the stream was clear and ducks had returned. Which is the best summary? (The council owns the stream. / Pupils cleaned up a polluted stream through action and persuasion, and wildlife returned. / In 2019, plastic bags were popular. / Ducks live near Hill School.) → Pupils cleaned up a polluted stream through action and persuasion, and wildlife returned.Prompt: What is the WHOLE text mostly about, not just one part?

Hook · 3 min

Read the first lines of a short text aloud and ask what students predict will happen and why.
Share the objective: Central ideas in complex texts. Read the success criteria together.

I do: model it · 7 min

Work through the example out loud, saying why you do each step, not just what you do.
Example: The invention of refrigerated shipping in the late 1800s did more than keep food fresh. It allowed meat from Argentina and New Zealand to reach European tables, reshaping farming, trade and diets across continents. Which choice best states the central idea?
Step 1: The main idea covers the whole text; details only cover a part.
Step 2: So the answer is: Refrigerated shipping had wide-reaching effects on global trade and food.
Answer: Refrigerated shipping had wide-reaching effects on global trade and food.
Pause after each step and ask a student to say what comes next.

We do: guided practice · 6 min

Do these together. Students try each step on whiteboards before you reveal it.
Use the hints as prompts rather than giving the answer.

Many people assume that creativity is a rare gift. Psychologists, however, increasingly describe it as a skill that grows with practice, feedback and a willingness to fail. Which choice best states the central idea? (Creativity may be a learnable skill rather than an inborn gift. / Feedback is always negative. / Most people are not creative. / Psychologists study failure.) → Creativity may be a learnable skill rather than an inborn gift.Prompt: What is the WHOLE text mostly about, not just one part?
For centuries, lighthouses guided ships with flame and later electric lamps. Satellite navigation has made many of them technically unnecessary. Yet communities have fought to preserve them, not for their function but for what they represent: safety, history and a sense of place. Which choice best states the central idea? (Ships no longer sail near coasts. / Lighthouses used flames. / Although lighthouses are less needed for navigation, people value them for their symbolic and historical meaning. / Satellite navigation is unreliable.) → Although lighthouses are less needed for navigation, people value them for their symbolic and historical meaning.Prompt: What is the WHOLE text mostly about, not just one part?

You do: independent practice · 7 min

Students work on the student sheet. Circulate and check the first two answers of every student early.
Students who finish: write a question of their own for a partner, with the answer.

The 5 questions are on the student sheet below, with answers in the key.

The invention of refrigerated shipping in the late 1800s did more than keep food fresh.

Two Texts on Memory

TEXT 1 For much of the twentieth century, many people imagined memory as a kind of recording device. An experience, according to this view, was stored somewhere in the brain like a film on a shelf; remembering meant taking the film down and playing it again. Forgetting was simply the film fading with age. This model was appealing because it matched how memory often feels: vivid, detailed and certain. TEXT 2 Decades of experiments have undermined the idea that memories are fixed recordings. In one well-known type of study, participants watch a video of a car accident and are later asked how fast the cars were going when they "smashed" or when they "hit" each other. Those who heard "smashed" not only gave higher speed estimates but were more likely, a week later, to report seeing broken glass – although there was none in the video. Such findings suggest that each act of remembering is partly an act of reconstruction, shaped by later information, expectation and language. A memory can feel certain and still be wrong.

Rethinking Screen Time

Few debates generate as much anxiety among parents as the question of screen time. Headlines warn that smartphones are "destroying a generation", while technology companies insist that their products connect and empower young people. The truth, as so often, is more complicated than either side admits. Part of the problem is that "screen time" is a crude measure. An hour spent video-calling a grandparent, coding a game or researching a school project is not the same as an hour spent scrolling through an endless feed of short videos. Researchers increasingly argue that what young people do on screens matters more than how long they spend on them. That said, quantity is not irrelevant. Several large studies have linked very heavy use – more than five or six hours a day of recreational screen time – to poorer sleep and lower wellbeing. Screens can displace other activities that support health: exercise, face-to-face friendship and, crucially, sleep. Light from devices and the stimulation of social media late at night can delay sleep for teenagers, whose body clocks already push them towards later bedtimes. It is worth noting, however, that most of these studies show correlation, not causation. Teenagers who are already unhappy may turn to their phones more, rather than their phones making them unhappy. Untangling cause and effect is notoriously difficult. What, then, should families do? Rather than fixating on a single number, experts suggest asking three questions. Is screen use getting in the way of sleep? Is it crowding out exercise and real-world relationships? And does the young person feel in control of it, or controlled by it? If the answers are reassuring, the exact number of minutes may matter less than we fear.

- B. Urban foxes have benefits as well as drawbacks, which should shape how cities treat them.
- C. Rats are a growing problem in cities.
