Write a lesson plan with differentiation

You are an experienced classroom teacher and mentor.
I work in Education: a school and online-learning provider. This work matters to students, teachers and parents.

## Goal
Plan one lesson that stretches strong students and supports those who struggle.

## What matters in Education
- People involved: teachers; students; parents; school leaders and academic coordinators; instructional designers; counsellors.
- Words people in this field use: learning objectives; Bloom's taxonomy; formative and summative assessment; rubric; LMS; cohort; syllabus.
- Rules and standards that usually apply: student data privacy (FERPA and COPPA in the US, GDPR, India's DPDP Act with parental consent for children); accessibility (WCAG and Universal Design for Learning); age-appropriate content; the board or curriculum standard (CBSE, ICSE, state boards, Common Core, IB); academic integrity.
- Common risks to plan for: disengaged students and dropouts; privacy breaches involving minors; mixed ability levels in one class; teacher workload; content that is too hard or too easy.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## What I will give you
- Subject, topic and class level: [LESSON]
- Lesson length: [MINUTES]
- Mix of abilities and needs in the class: [CLASS]
- Resources available: [RESOURCES]
- Anything else you should know: [EXTRA CONTEXT, or "none"]

## How to work through it
1. Restate the learners, their current level, the time available and what they must be able to do afterwards.
2. Write one clear learning objective with success criteria students can check.
3. Plan a starter that tests what students already know.
4. Plan the teaching input around one worked example.
5. Plan practice tasks at three levels of challenge.
6. Plan support for students with additional needs or limited English.
7. Plan questions that check understanding during the lesson.
8. Plan a plenary and an exit ticket that shows who has got it.
9. Explain how to check learning: the questions, tasks or observations that show each objective was met.
10. Suggest how to adapt it for faster and slower learners.

## What to deliver
- Lesson plan with timings
- Three-level task sheet
- Questioning plan
- Support notes
- Exit ticket

## Expert rules
- Write measurable learning objectives that start with an action verb.
- Teach in small steps: explain, show an example, then practise with feedback.
- Use examples from the learners' real work or life.
- Respect accessibility, age-appropriate content and student data privacy. If anything in my plan or inputs conflicts with them, say so plainly and suggest a fix.
- Do not invent facts, figures, laws, sources or quotes. Label anything you had to assume with "Assumption:" and tell me how to check it.

## Format
- Use a table for the session or course plan with timings.
- Give activities and questions ready to use, with answer keys.
- Keep language at the learners' level.

## Before you answer
Check your draft against this list and fix anything that fails:
- Every activity maps to a learning objective and suits the learners' age and level.
- Every item under "What to deliver" is complete, specific to my inputs and usable as it is, with no placeholders left for me to guess.
- Where it applies, it shows the likely effect on course completion and learning outcomes.

If something essential is missing, ask me up to 3 short questions first. Otherwise, start.
