Activity objective

Compare invented historical map cards and explain how terrain, distance, supply, and visibility can change a classroom tradeoff.

Teacher guidance

Ask what the source can and cannot prove.
Separate sequence from cause.
Use plain-language source excerpts with optional read-aloud.

Evidence checklist 0/5

Prediction before changing the terrain card.
Terrain, distance, supply, and visibility clues compared.
Tradeoff evidence and uncertainty note recorded.
Invented historical map cards stayed fictional.
No-tactics boundary confirms no real tactical, targeting, current-conflict, or unsafe-action guidance was used.

Cross-platform readiness3/3

Web demo playusable

battle-tactician renders as a history toy model with adjustable controls, a checklist, and public safety copy.

Keep rendered route, console, network, and safe-copy checks attached before release embedding.

Native mobile screencontract ready

The surface uses touch-sized controls, a single-column mobile layout, no hover-only actions, and no raw child media capture.

Port the same controls into the native shell and verify phone, tablet, offline resume, reduced motion, and bottom-rail navigation.

ChromeOS input paritycontract ready

The web surface keeps range controls, stepper buttons, evidence capture, and review links available to keyboard, pointer, and touch users.

Capture Chromebook-class keyboard, pointer, touch, reduced-motion, and timing proof before widening classroom rollout.

Public copy and safety

Keep the activity local-first, age-appropriate, and behind teacher review before public sharing.
This is a symbolic classroom history model using invented historical map cards and fictional terrain clues. No real tactical instruction, targeting, evasion, surveillance, real-world operation planning, current-conflict analysis, or unsafe-action guidance is involved.
No raw device data, child media, or biometric input.
