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.
TEACHER FEEDBACK
"I tried GeoGuessr but it was too hard for the kids and just random points. EraPin is 5 historical locations with unlimited time — the kids like the game aspect and I debrief them about the events when they finish."
— BROCK SANITER, 7TH GRADE, ELMWOOD SCHOOLS
WHAT STUDENTS SAY
"They play a lot of different games in school. They said this was really amazing and they really saw value in it as a school tool."

- 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 800+ 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-context retrieval. 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.
