A history teacher in Illinois took on my offer to build her a custom pack sent me her unit materials for end-of-year teaching, and I built Maya, Aztec, and Inca packs from them overnight. She ran the Maya pack with 27 students yesterday and emailed back saying her 6th graders "LOVED" it (her caps).
The packs run on EraPin — a free classroom tool where students see archival photos, drop a pin on a world map, and guess the year. Five rounds, ~5 minutes per session. No student accounts, just a 4-character room code.

If you have an end-of-year topic not covered in the library,
send me your scope or unit notes and I'll build a pack. That's how the Maya one happened.
