Lesson Plan Builder

Q: How do I know the Lesson Plan Builder output is good?

The skill verifies itself against its own quality checks: The objective is measurable with an observable verb and stated evidence; The plan fills the period bell-to-bell with a hook and an explicit close; At least one check for understanding, with a reteach trigger; Differentiation covers support, extension, and language needs — concretely.

🔵 Stable🕐 updated 2026-10-06 🔷 SkillSpec L3 pm-teaching

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.

What to give it

▸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

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓The objective is measurable with an observable verb and stated evidence

✓The plan fills the period bell-to-bell with a hook and an explicit close

✓At least one check for understanding, with a reteach trigger

✓Differentiation covers support, extension, and language needs — concretely

✓Activities actually produce the evidence the objective names

⚠️ What it refuses to do

"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
