| name | lesson-plan-builder |
| description | Build a standards-aligned K-12 lesson plan with clear objectives, a timed activity sequence, checks for understanding, and differentiation. Use when asked to plan a lesson, write a lesson plan, align a lesson to a standard, or turn a topic into a class period. Produces measurable objectives, a bell-to-bell timeline (hook → instruction → practice → close), formative checks, differentiation for varied learners, and the materials list. |
Lesson Plan Builder Skill
A good lesson plan is not a topic and a worksheet — it's a designed arc where every minute has a purpose and the teacher knows, before the bell, how they'll tell if it worked. This skill builds a plan backward from a measurable objective, with the checks for understanding and differentiation that make it survive a real classroom.
Working from a brief
Given a topic, grade, and standard (or just a topic), write the full plan — infer the grade-appropriate objective and align to a plausible standard, labeling the assumption. Fit it to one class period unless told otherwise.
Required Inputs
Ask for (if not provided, else infer and label):
- Grade level and subject, and the topic or standard
- Class length and any constraint (materials, tech, class size, mixed levels)
- Where students are — prior lesson / what they already know
Output Format
Objective(s)
Measurable and student-facing: "Students will be able to [verb] [content] as measured by [evidence]." Use observable verbs (identify, compare, model), not "understand."
Standard alignment
The standard code + a one-line note on how the lesson meets it (labeled as inferred if you supplied it).
Lesson timeline (bell-to-bell)
| Time | Phase | Teacher does | Students do |
|---|
| 0–5 | Hook / do-now | | |
| 5–15 | Direct instruction | | |
| 15–30 | Guided → independent practice | | |
| 30–40 | Check + close | exit ticket | |
Checks for understanding
The formative moments — a question, a quick write, an exit ticket — and what answer tells you to move on vs. reteach.
Differentiation
Concrete moves for students who need support, who finish early, and for language learners (not "give more time").
Materials
Everything needed, ready to gather.
Quality Checks
Anti-Patterns
- "Students will understand X" — not observable, not assessable
- A topic and a worksheet with no arc or timing
- No check for understanding until the summative test
- Differentiation that's only "more/less time"
- Activities that don't produce evidence of the stated objective
