AI4K12 Five Big Ideas crosswalk

Plio's AI track is organized around 27 concepts. Each is mapped to one primary AI4K12 Big Idea and, where it carries real weight elsewhere, a secondary one. The lesson IDs are the ones that exist in the product today — this table is generated from the curriculum source, not written by hand.

Plio Academy's own alignment claim at the concept level. Plio is not affiliated with or endorsed by AI4K12. The Five Big Ideas framework is published by AI4K12 (AAAI/CSTA, NSF-funded) under CC BY-NC-SA; referenced, not reproduced. Generated 2026-09-10.
