Lesson Plan Design

Purpose

Turn a topic, a group of learners, and a fixed time slot into a lesson someone else could teach without asking follow-up questions. One lesson, one main objective, evidence planned before activities, and a sequence where learners do the verb in the objective, not just hear about it.

This skill is for a single lesson. For a whole course or multi-week program, use a course outline skill first, then apply this skill lesson by lesson. For a training video or a self-paced module, the timing and practice rules still apply, but replace live checks with built-in pauses and self-checks.

The core method is backward design from Wiggins and McTighe: desired result first, acceptable evidence second, activities last. The sequence inside the lesson draws on Gagne's nine events, the BSCS 5E order where inquiry fits, and gradual release of responsibility from Fisher and Frey.

Workflow

1. Fix the frame

Collect, and ask only for what is missing:

• Learners: who they are, age or role, group size, what they already know, and any known misconceptions or common errors.
• Setting: classroom, workplace, or one-to-one. Live, online, or in person. Total minutes available, stated as a hard limit.
• Objective source: a standard, curriculum line, job task, exam, or requester goal the lesson must serve. Quote it back if one was given.
• Constraints: room, devices, materials on hand, language needs, accessibility needs, and anything that cannot be used.
• Follow-on: what the next lesson or the real-world task assumes this lesson delivered.

If total time is not given, propose one and state it: 45 to 60 minutes for a classroom lesson, 30 to 60 for workplace training, 25 to 50 for one-to-one. Do not plan an untimed lesson.

2. Write one objective, ABCD complete

Write one main objective. A second supporting objective is allowed only if it is a prerequisite step toward the main one. Three or more objectives in one short lesson usually means no objective gets practiced enough to stick.

Each objective must have all four parts:

• Audience: the learner, named once.
• Behavior: one observable verb plus its object. One verb per objective.
• Condition: the materials, situation, or limits given when the learner performs.
• Degree: how well, how many, or within what limit counts as success.

Pick the verb from the revised Bloom levels: Remember (define, list, identify), Understand (explain, classify, summarize), Apply (solve, demonstrate, use), Analyze (compare, differentiate, examine), Evaluate (judge, justify, critique), Create (design, build, compose).

Banned as objective verbs: know, understand, learn about, appreciate, be aware of, be familiar with. Replace them with the behavior that would prove them.

Worked rewrite:

• Weak: "Learners will understand fractions."
• Strong: "Given a set of paper strips and a number line (condition), the learner (audience) will place six unit fractions in order (behavior) with no more than one placement error (degree)." Verb level: Apply.

State the objective to learners at the start of the lesson, in plain language. Gagne lists informing learners of the objective as the second event for a reason: learners aim better when they know the target.

3. Plan the evidence before the activities

Decide how you will know the objective landed, before picking any activity. This is backward design stage two, and skipping it produces fun lessons that prove nothing.

• Closing check: one task at the end that requires the same verb, at the same level, as the objective. Exit ticket, worked problem, short demonstration, or oral explanation all count, if every learner produces one.
• Success rule: write what a passing response looks like, and what a near miss looks like. Name the specific error you expect to see most.
• Decision rule: write what happens next for each result. A usable default, framed as a planning rule not a research finding: most learners pass, move on and note the few who need follow-up; about half pass, reteach the missed part at the start of the next lesson; few pass, reteach this lesson a different way before advancing.
• Mid-lesson hinge: one quick check halfway, with responses from every learner (show of hands with options, mini whiteboards, a single poll question, thumbs with a reason). If the hinge fails, the plan must say which backup move runs. A check with no planned response is decoration.

A check is only formative if its result changes what you do. Write the change into the plan.

4. Build the sequence

Order the lesson so attention, recall, input, practice, and transfer happen in that broad flow. Use one of these spines, and name which one you used:

Spine A, gradual release. Best for skills and procedures, and the default for workplace and one-to-one lessons.

1. Open and recall, 5 to 10 percent of time. Hook tied to the objective, state the objective, recall the prior learning this builds on.
2. Focused instruction, I do it. Model the task while thinking aloud. Show one good example and, where errors are common, one flawed example with the error named.
3. Guided practice, we do it. Learners try with prompts, cues, and immediate feedback. Teacher or tutor corrects in the moment.
4. Collaborative or paired practice, you do it together. Learners work in pairs or small groups on a task that needs the new skill. Skip this step for one-to-one lessons and extend guided and independent practice instead.
5. Independent practice, you do it alone. Each learner performs the objective verb alone, under conditions close to the closing check.
6. Close, see step 6.

Spine B, 5E. Best for concept and inquiry lessons, mainly in science and discovery settings.

1. Engage: short prompt or phenomenon that surfaces prior ideas.
2. Explore: shared hands-on or data experience before any formal terms.
3. Explain: learners state their account first, then the teacher introduces the formal concept, term, or method.
4. Elaborate: apply the concept to a new case or a harder variant.
5. Evaluate: the closing check from step 3, plus learner self-assessment.

Rules that apply to either spine:

• Learners practice the objective verb for at least as long as they listen to input, at Apply level and above. If input is winning on time, cut input, not practice.
• Chunk input into blocks of about 10 minutes or less, each block followed by a learner action: answer, sort, solve, discuss, or do. Long unbroken explanation is the most common timing and attention failure.
• Every activity must name the segment of the objective it serves. An activity that serves no part of the objective gets cut, however engaging it is.
• Plan transitions explicitly: what learners do with materials, where they move, what the instruction sentence is. Transitions are where untimed lessons bleed minutes.
• Build in one flex move: a cut if time runs short (name the segment to drop) and an extension if the group finishes early (a harder variant, not busywork).

5. Time it so it survives contact

• Give every segment a minute range, not a single number, for example 8 to 10 minutes. Sum the top ends. The sum must fit the hard limit.
• Reserve a buffer of about 10 percent of total time. State it explicitly, either as its own line or as a named held portion of the closing segment. Buffer absorbs late starts, questions, and one reteach. Do not hide buffer silently inside other segments.
• Protect the close: the closing check and summary get their minutes first when cutting. A lesson that runs out of time before the check has no evidence.
• If the plan is over time, cut in this order: first enrichment examples, second a second practice round (keep the first), third shrink input by moving detail to a handout. Never cut the hinge, the independent practice, or the closing check to fit.
• Write a Plan B timing column for the predictable disruption in that setting: tech failure in a classroom, a late start at work, a learner who needs the prerequisite retaught one-to-one.

Validate a JSON version of the plan mechanically when you produce one:

python3 bin/lesson_check.py plan.json

The checker flags banned verbs, missing ABCD parts, missing hinge or closing check, segment sums over the limit, missing buffer, and missing materials. See references/worked-plans.md for the JSON shape.

6. Close the lesson on purpose

The last segment does three jobs, in order:

1. Summary in learner words: learners state what they can now do, tied back to the objective stated at the start.
2. Closing check: every learner completes the evidence task from step 3, collected or observed, not voluntary.
3. Bridge: one sentence on where this gets used next, in the next lesson, on the job, or in real life. This is Gagne's retention and transfer event, kept short.

Do not introduce new content in the close. New content in the final minutes gets neither practice nor a check.

7. Prep materials and access

List materials as a prep checklist, not prose:

• For the teacher: slides or board plan, worked examples, answer key or success criteria, hinge question with its options, closing check copies or link, timer.
• For learners: handouts, manipulatives, devices, logins, and anything that must be printed, charged, or booked ahead.
• Setup: room layout for the grouping you planned, grouping method (pairs assigned how), and what is on desks or screens when learners arrive.

Apply Universal Design for Learning from CAST at plan time, not as a retrofit:

• Representation: give the core content in at least two forms, for example spoken plus visual, or text plus diagram.
• Action and expression: where the objective allows, let learners show the skill in more than one format. If the objective fixes the format, say so and vary the practice format instead.
• Engagement: offer one real choice inside the lesson (which case, which problem set, which order) without changing the objective.

Also plan differentiation in three lines: support for learners missing the prerequisite (a scaffold, a worked example to keep, a reduced first task), core task for most learners, and extension for fast finishers. One line each is enough at lesson scale.

8. Run the quality checks

Before delivering, run every check. Fix failures, do not annotate them away.

• [ ] One main objective, ABCD complete, one observable verb, no banned verbs.
• [ ] Closing check requires the same verb at the same level as the objective, and every learner produces one.
• [ ] Hinge check at mid-lesson, with a named backup move if it fails.
• [ ] Decision rule written for pass, partial, and fail results on the closing check.
• [ ] Practice time is at least input time at Apply level and above.
• [ ] Segment ranges sum, at their top ends, within the hard limit, buffer stated explicitly.
• [ ] Flex cut and early-finisher extension both named.
• [ ] Every activity maps to the objective. No orphan activities.
• [ ] Materials list covers teacher, learners, and setup, with anything to print or book flagged.
• [ ] Representation, expression, and engagement each have one planned option.
• [ ] Close has summary, check, and bridge, and introduces no new content.
• [ ] Someone else could teach from this plan alone: instructions, questions, and expected answers are written out, not implied.

Output Contract

Deliver a lesson plan with these sections, in this order:

1. Header: title, learners, setting, total minutes, spine used (gradual release or 5E), objective source if any.
2. Objective: the ABCD objective, plus its Bloom level and the plain-language version stated to learners.
3. Evidence: closing check task, passing and near-miss descriptions, decision rule, and the mid-lesson hinge with its backup move.
4. Sequence: a timed segment list. Each segment has minutes (range), what the teacher does, what learners do, and grouping.
5. Materials and setup: the prep checklist from step 7, plus differentiation in three lines.
6. Timing safety: buffer line, flex cut, extension, and Plan B for the likely disruption.
7. Close: summary prompt, closing check delivery detail, and the bridge sentence.

Worked plans for a classroom, a workplace, and a one-to-one lesson, in full, are in references/worked-plans.md. Use them as shape and depth references, not as content to copy into a different topic.

If the requester wants a machine-readable plan, also deliver the JSON form described in references/worked-plans.md and run bin/lesson_check.py on it. Report the checker result with the plan.

Operating Rules

• One lesson means one sitting. If the request needs several sittings, say so, deliver the first lesson in full, and outline the rest in one line each.
• Never invent a standard, curriculum code, exam requirement, or workplace policy. If the requester names one, use their wording. If none is named, write "objective source: requester goal" and move on.
• Do not pad a short lesson to fill a long slot with unrelated content. Extend practice, add a transfer task, or end early and say why.
• Timing numbers in this skill are planning defaults, not research findings. Label them as defaults when a requester asks where they came from, and adjust them to the setting without apology.
• For young learners, shorten input chunks, add movement or material handling between segments, and make the closing check oral, drawn, or performed if writing would test writing instead of the objective.
• For workplace lessons, tie the condition in the objective to the actual job task, tools, and standard of performance used at work. A training example that differs from the real task must be flagged as a practice proxy.
• For one-to-one lessons, drop group segments, spend the saved time on guided and independent practice, and make the hinge a direct question the learner answers aloud or in writing every few minutes.
• Keep language plain. No jargon without a one-line plain explanation on first use.
