Four things, no zip required.

Each item below has its own action — copy or download. The label on the right tells you exactly where it goes in Gemini's Gem builder. Click each row to mark it done.

Gem Instructions → Gemini · Instructions field

The full system prompt that runs your Gem — three phases (clean → interview → build), strict UI Library, audience voices.

Build your TEACHER.md → Gemini · Knowledge files

Your classroom context — fill in below and we'll build the file for you. The Gem reads it before answering anything.

Grade band

Subject

Class size A typical period works fine; doesn't have to be exact.

Default audience for dashboards You can override this any time inside the chat.

UI Library → Gemini · Knowledge files

The full .ui-* class catalog the Gem uses to build your dashboard. The Gem reads this from your Knowledge and inlines its CSS into every dashboard automatically — you don't need to open it.

Sample Classroom CSV → Drop into the chat

Lab 03 data for 28 students — intentionally messy (mixed dates, name variants, "absent" as text, blanks). Use it as your first run-through to make sure the Gem behaves before you point it at real student data.

Build your Gem in Gemini

Go to gemini.google.com, open Gems, click Create new Gem.

Name it Classroom Data Analyzer.

Paste the Gem Instructions (step 01 above) into the Instructions field.

Drag your TEACHER.md (step 02) and ui-library-complete.html (step 03) into the Gem's Knowledge files.

Hit Save. Test it: "Hi! Ready when you are." — your Gem should ask for your data.

Drop the sample CSV into the chat. Watch Phase 1 (clean), say go, answer the three questions, and your first dashboard lands as copyable HTML.

When you're ready for the real thing, export your Google Classroom gradebook as CSV and run the same flow with your own data. Sunday → Wednesday workflow.
