Do you mean the Great Law of the Haudenosaunee [1]? I.e., the constitution of the Iroquois Confederacy? The place where the founding fathers of the US got the idea of separation of powers? The form of government of one of the major regional powers at the time the US was formed? Don't know why your daughter's teachers would bother teaching her about that. Sure, it's awful if they were neglecting all those other things, but seriously, anyone learning American colonial-era history needs to learn about the Iroquois Confederacy.
