What Students See

Each round shows a historical photograph paired with a written geographic clue — something like "a fortified city on a broad tidal river, near the southeastern corner of a large island off northwestern Europe." Students decode the spatial language, combining absolute location reasoning (specific coordinates, named places) with relative location reasoning (positioned relative to neighbouring features). They study the image for additional visual context — architecture, vegetation, signage, clothing — then place a pin on the world map and guess the year using a slider. Points are awarded for accuracy in both location and time.

Variable rounds per session — pick 5 to 30 events per pack-published session, or play the daily 5-round activity. Each round scores out of 5,000. After the session, students see their total, performance badges, and the class leaderboard — but not the answers, so it's safe to project.

Inquiry opener for a new unit. End-of-unit review. Sub-day session that runs itself. Geographic-reasoning and spatial-thinking practice. Chronological-thinking review. Geography-skills practice.

Build Your Own Session

By default, students play the same daily EraPin as players worldwide. But you can publish your own session to override it for your classroom.

Pick a pack: Browse 100+ curriculum packs, choose exactly the events you want, and publish for any date.

Add specific events: Search Wikipedia by name and add them to your session — or generate events by topic for anything we don't cover yet (a daily generation limit applies).

Frequently Asked Questions

Is EraPin really free?

Do students need accounts?
No. Students click a link, enter their first name, and play. No email, no password, no downloads.
What devices does it work on?
Chromebooks, iPads, phones, laptops — any device with a browser. No app to install.
How long does a session take?
Variable — pick the round count when you publish a pack (5 to 30 events). The daily activity is 5 rounds, untimed. Sized to fit any time you have.
Can I see my students' scores?
Yes. Live leaderboard updates as students complete rounds. Project it on a smartboard.
Can I run sessions about specific topics?
Yes. Browse 2,500+ events across APUSH, AP World, KS3, NY Regents, and other curricula. Pick a pack, choose a length (5–30 events), publish.
How is it different from generic map tools?
EraPin uses real historical events tied to curriculum frameworks instead of random Street View locations. Students practice absolute and relative location reasoning, chronological thinking, and historical reasoning. Each clue is written to teach geographic literacy — students decode descriptions like "between the Yellow Sea and the Sea of Japan" or "directly across the Channel from southern England" to locate specific events. Includes live class leaderboard. Completely free.
What subjects does it cover?
World history, geography, chronological thinking, and spatial reasoning. Aligned with AP World History, APUSH, GCSE, KS3, KS4, IB History, NY Regents, and general social studies. Particularly strong for absolute and relative location practice — a core requirement in the C3 Framework and most geography standards.
Is content appropriate for all ages?
Events sourced from Wikipedia. Teachers preview all rounds before publishing and can remove any they consider unsuitable.
Can students see each other's answers?
The final screen shows scores and performance dots but not the actual answers (city, country, year). It's safe to project on a classroom screen.
