Respect to you.
One of the things I would recommend is exposing them to the food, the music, the language, etc. Depending on what kind of school it's at will probably impact things in terms of teaching religion/spirituality but there are practical applications that can be taught.
When you talk about the food and let them taste it you can talk about where it came from and how it is important that we try to live naturally with the Earth, not against it.
It would also be interesting if you could trace one or more people's DNA back to Africa and kind of blend the science in with the movement of people.
Most importantly... teaching them about H.I.M and Marcus Garvey; showing them great modern cities in Africa their art and architecture and showing how African Kings and queens lived, how we had castles in Africa, not just pyramids. And ultimately, that they shouldn't forget where they came from but build upon that history as well as their other histories to build wealth and success for themselves as well as their communities. And Hopefully, soon there will be a Garvey movie that we can show our children.
