Group Activity for One Class Period

ROLE: Act as a maths teacher who runs lively, well-organised group activities that keep every student involved.

CONTEXT: I teach [CLASS/GRADE] under [BOARD e.g. CBSE / ICSE / State Board]. I want one GROUP ACTIVITY on [TOPIC e.g. fractions / linear equations / probability] for groups of [GROUP SIZE e.g. 4]. It must fit a [PERIOD LENGTH e.g. 40] minute period and keep all students active, not just the strongest.

YOUR TASK:
1. Design one collaborative activity (a challenge, a game, or a build) on the topic.
2. Give each group member a named role with a clear job.
3. Provide a minute-by-minute timeline that adds up to the period length.
4. State the rules clearly so the class runs smoothly.
5. Include the actual maths content groups will work on (questions, cards, or data).
6. Add a fast 5-mark assessment to grade each group.

INPUT: Here is my topic and class size: [PASTE TOPIC AND CLASS DETAILS HERE]. If blank, choose a strong activity for the class and board above.

HOW TO WORK IT OUT: Plan internally and make sure the timeline truly adds up to the period length; list each stage's minutes and show the total. Ensure every maths question or value is correct, and VERIFY any answers by a second method. Never invent formulas. Keep all maths legible in clean plain text or simple LaTeX.

OUTPUT FORMAT (use these exact headings in this order):
1. ACTIVITY TITLE
2. GOAL (one line)
3. GROUP ROLES (role name + job)
4. MATERIALS NEEDED
5. MINUTE-BY-MINUTE TIMELINE (stage | minutes; final Total)
6. THE ACTIVITY CONTENT (the questions/cards/data, with answers in a separate ANSWER KEY block)
7. RULES FOR THE CLASS
8. QUICK ASSESSMENT (5 marks, what earns each mark)
9. TEACHER TIPS

RULES: Every student must have something to do at all times. Be concrete; no vague 'discuss'. Keep language short and friendly.

FORMAT THE OUTPUT — PRIMARY DELIVERABLE:
Return one complete, editable document ready to paste into Word or Google Docs. Use a descriptive title, short section headings, readable paragraphs, numbered actions and tables only where they make the material easier to use. Include every requested section; do not return formatting advice instead of the document.


MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.

CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.

GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
