Mini 45‑minute lesson plan you can try tomorrow

Topic: Simple interest and savings (9–10 grade example)
Learning goal: Calculate simple interest and explain how changing rate/time affects total.

0–5 min — Hook: Two real-world examples (choose one). Quick poll: “What would you do with $500?”
5–10 min — Diagnostic: 3 rapid questions to check prior knowledge (percent → decimal conversions). Use results to suggest tier choices.

10–15 min — Mini teaching (whole group): model simple interest formula and one example.

15–35 min — Tiered work (students choose or are assigned)

• Bronze (guided): Fill a worksheet with 5 fill‑in calculations; follow step prompts.
• Silver (apply): Given 6 problems with different rates and times, calculate totals and graph one example.
• Gold (extend): Create a 2‑year savings plan and an advice blurb: “If you want to double X in Y years, what rate is needed?” Explain reasoning; present as a 1‑minute peer pitch.

35–40 min — Quick peer check: students swap answers with same-tier partner or cross-tier buddy for one feedback point.

40–45 min — Exit slip: “One thing I learned + one question.” Teacher reads slips and plans follow-up (small group reteach or confirm mastery).

Final tips — keep it simple and student‑centered

• Start small: tier one activity in a week before trying a whole unit.
• Use neutral labels, keep dignity high.
• Always link the tier to a common learning objective.
• Make choices meaningful and linked to real life (novelty and usefulness boost intrinsic motivation).
• Use data from quick checks/exit slips to adapt next lesson.

If you want, you can ask AI (ChatGTP, Gemini, etc.) to:

• Draft three tiered tasks for a specific lesson you’re teaching this week.
• Make a short rubric you can paste into your gradebook.
