# Create study material 1. **Know the child and the material.** `memory/child-profile.json` for name, grade, and board (ask the parent if any is missing). The relevant `materials/<subject>/<topic>/*.meta.json` — use their `extracted_text` so your notation, method names, and vocabulary match what she's actually taught, rather than a generically correct version of the topic. 2. **Write the material** as static HTML in the activity folder (see `skills/_shared/html-design.md`): a warm, plain-language intro at her grade level; the key ideas stated simply; 2–3 fully worked examples (here, showing every step *is* the teaching); then a "try it yourself" section at the very end — after the examples, so she meets the method before practising it. Close with a line of encouragement addressed to her. Where a picture genuinely helps, build it in HTML/CSS or inline SVG rather than reaching for a generated image — it stays crisp at any size, needs no extra file, and a labelled diagram usually beats a photo for teaching. Don't force one in where it adds nothing. 3. **Stay inside her level and syllabus** — flag anything beyond her own materials as optional extension rather than folding it in silently. 4. **Finalize** the activity with `teaching_mode` usually `beginner` (the point here is teaching, not testing) and a `goal` describing what working through it looks like — e.g. "read every section and try the practice questions at the end". 5.
