For people who teach in a school or train adults: lessons, tests, simplified texts, marking with a mark scheme, letters to parents and carers, marks, course timetables, a tutor that does not give the answer, minutes of meetings. Nine cases, each with the request to copy and adapt and with what to check before the material reaches pupils.
The examples use fictional documents. Each case lists the stages of the manual that teach the move. The cases were tested in Claude in the Italian edition of this guide, and the cases that report what the model did in a test were tested again in English on these documents, in November 2026. Where a test showed a typical mistake, the case says so.
Where the test used a fictional document, the case offers it for download: you can redo the test and compare the answer with what the case describes.
Before you start: pupils' data and the mark
People who teach work with people, often children, and their data needs more care than an adult's. Four rules apply to every case below.
- No pupils' names, no diagnoses, no information about families in a personal tool. Upload a piece of work without the name; a list of marks with codes (S01, S02).
- If your school or training provider gives you its own tool, ask what you are allowed to upload (fact sheet "If the tool comes from your office").
- The mark stays yours. The model can propose a mark with the reasons next to it; the teacher decides the assessment and signs it.
- Whatever a pupil reads, a test, a simplified text, a comment, goes through you first, in full.
1. Planning a lesson from a text
The situation. A page of the textbook and a fifty-minute lesson to build.
The request. Upload or paste the page, then:
"Plan a 50-minute lesson on this text for a Year 8 class: objectives, an opening question, the explanation split into steps, a pair activity, and a final check with three questions. Give the minutes for each part, and the total. Use only the content of the text; if you suggest something the text does not say, flag it."
To redo the test. The fictional document used: case1_water_cycle_text.txt.
What to check. The total of the minutes: 50-minute lessons that last 65 are a classic. The added content: numbers, examples and facts the text does not contain are possible errors, and in any case things the class will not find in the book. The activity: can it really be done, with that material, in that time?
Stages. 2 (the same request, done well), 3 (a document of your own).
2. A test with the answer key
The situation. From the same text you need a test: closed questions, two open ones, the answers and the marking criteria.
The request.
"From the text, prepare a test: 8 multiple-choice questions with 4 options each and 2 open questions. Then the answer key, with the line of the text each answer comes from, and the marking criteria for the open questions. No questions on content that is not in the text."
What to check. Every question against the text: the line quoted must really answer it. The wrong options: sometimes a "wrong" one is also right, and the pupil who picks it is correct. Take the test yourself before you hand it out: it is the quickest check. In the English test the eight closed questions were right, and the model wrote the wrong options so that none was true in real life and simply missing from the text. On the same text in Italian, one question had come out reversed: it asked what feeds infiltration and gave groundwater as the answer, when it is infiltration that feeds the groundwater, while the line quoted in the key was right. You only see it by answering.
3. The same text, made simpler
The situation. Some pupils need a more accessible text: short sentences, common words, the same substance.
The request.
"Rewrite this text in a simplified version: short sentences, one piece of information per sentence, common words. Keep all the concepts and the technical terms, explained the first time they appear. At the end, list the technical terms, so I can check they are all there."
What to check. Lost concepts: a simple version tends to drop the hard step, which is the one to learn. Compare the list of terms with the original text. The explanations of the terms: correct, with no content errors. In the English test the terms were all there and explained correctly, and the model listed three definitions it had added that were not in the text (vapour, hail, cycle): those are the lines to check. On the same text in Italian, vapour had become water "as light as air": simple, and imprecise, the kind of sentence a pupil remembers. Use the simplified text alongside the original. The support for a pupil with special educational needs is agreed with the school's SENCO (special educational needs co-ordinator) and, where the pupil has one, set out in the EHC plan.
4. Marking with a mark scheme
The situation. Thirty pieces of written work and a mark scheme. The scheme has to be applied to all of them in the same way.
The request. Paste the task, the mark scheme and one piece of work, without the name, then:
"Apply this mark scheme to the piece of work. For each criterion: the mark you propose and the sentence from the work that justifies it. Then the total and a comment for the pupil, four lines, with one thing that went well and two to improve, each with an example. I decide the mark: yours is a proposal."
To redo the test. The fictional document used: case4_essay_and_mark_scheme.txt.
What to check. The quotations: a mark without the sentence that justifies it does not count. Consistency: try the same scheme on two pieces you have already marked and compare. The scheme itself: in the test the model noticed that levels 1 to 4 were not described and said the marks depended on its own reading. It proposed 8 out of 16, quoted a sentence for each mark, and said which criterion it was least sure of (vocabulary, which a stricter reading would bring to 7). A scheme with the levels described leaves less room for interpretation, by the model and by colleagues. The comment: it has to speak to that pupil, about that piece of work, in the tone you would use.
Stages. 2, 14 (a custom assistant).
5. The letter to parents and carers
The situation. An educational visit: dates, times, costs, consent. The letter has to be written, and clear.
The request. Paste your notes, then:
"Write the letter to parents and carers for this visit: what, when, times, the voluntary contribution with the breakdown, how and by when to pay, consent, what to bring, which staff are going. One page, polite tone. Use only the facts in the notes. At the bottom, the consent slip to sign and return."
To redo the test. The fictional document used: case5_trip_notes.txt.
What to check. Dates, times and amounts, against the notes: the total has to match the items. The deadlines, repeated on the consent slip. The wording of the payment: if your notes say "voluntary contribution", the letter must not turn it into a charge parents have to pay. Additions: a phone number, a meeting point or lunch arrangements that were not in the notes. In the test the letter kept "voluntary contribution" with the breakdown and the confidential route for families who cannot pay, and left the school name, date and signatory as gaps to fill.
Stages. 2, 6 (Word and Outlook).
6. The class's marks
The situation. The mark book exported, three tests, a few absences. You need the averages, the test that went worst, and who is struggling.
The request. Upload the file with codes instead of names, then:
"Use a program to calculate each pupil's average on the tests they actually sat, the average of each test, and the list of pupils below 60%. An empty cell is an absence, not a zero. List separately the pupils with only one test."
To redo the test. The fictional document used: case6_marks.csv.
What to check. The empty cells: if they become zeros, an absent pupil lands on the "below 60%" list without belonging there. The pupils with only one test: their average cannot be compared with the others. The list is a starting point for the progress review meeting; the assessment stays with the teachers.
Stages. 7 (Excel: formulas, data and charts), 4.
7. The timetable for a training day
The situation. A course for adults at a company: the modules exist, and the day has to be built with times and breaks.
The request. Paste the modules, their length and the constraints, then:
"Build the timetable for the day with the start and end time of each module and each break, keeping to the constraints. Use a program to calculate the total time and tell me how much margin is left. If the modules do not fit, tell me instead of shortening them."
To redo the test. The fictional document used: case7_course_modules.txt.
What to check. The times, one after another: a module that ends at 11:15 and the next one starting at 11:00 is a mistake you only see by reading. The constraints (the order of the modules, the test at the end). The margin: a day with no margin cannot absorb participants' questions.
8. A tutor that does not give the answer
The situation. You want pupils to use the model to practise, without it doing their homework for them.
The request. In a project or an assistant (stage 14), in the instructions:
"You are a tutor for Year 8 pupils. Never give the solution to an exercise, even if the pupil insists. Ask one question at a time to lead them to find it themselves, and if they get it wrong, tell them where to look. When they reach the solution, ask them to explain it in their own words."
Then try it yourself, playing the pupil who insists: "Just give me the answer, I'm in a hurry."
What to check. Insistence: that is where tutors give in. Try it three times, with different requests. The level: the questions must suit the pupils' age. Remember that a pupil can always open a chat with no instructions: the tutor works if the homework asks for the reasoning, and not only the result.
Stages. 11 (getting it to know you), 14.
9. The minutes of the progress review meeting
The situation. The notes taken during the meeting have to become the minutes, with what was decided and what was only proposed.
The request. Paste the notes, with codes instead of pupils' names, then:
"Write the minutes in the usual form: date, time, present and absent, items discussed, decisions. Keep the decisions separate from the proposals. Do not include pupils' health information: write 'confidential matter, on file'. List the actions separately, with who and by when."
To redo the test. The fictional document used: case9_meeting_notes.txt.
What to check. Proposals that became decisions: "we will ask the headteacher whether there is budget" does not mean "the sessions are approved". Health information: a diagnosis does not go into ordinary minutes. The actions: each with a name and a date, if the notes give them; otherwise "to be confirmed".
Cases tested on 7 November 2026.
