K-12 Lesson Prep

Skill last updated August 28, 2026

​

Overview

The K-12 Lesson Prep ↗ skill helps a teacher prepare for, and internalize, an existing lesson before teaching it:

• Build mastery of what’s important about the lesson and why
• Anticipate how to distinguish between student mastery and a need for more support
• Walk into class confident in their understanding of the lesson’s content and focus

This skill’s output is not a rendered file – it is the conversation itself. The skill presents the teacher one small piece of student work at a time, then waits for the teacher’s read before offering its own. A short teacher-only prep note may be produced at the end, but this is a byproduct of the conversation, not the point of it.
