Nova Scotia has Afrocentric math for black students that teaches them using Egyptian pyramids because they waz kangz (note - blacks arent egyptian and are from the sub-saharan thousands of kilometers away with huge environmentally unpassable terrain and would not have the skill or knowledge to create the pyramids nor be able to en masse travel there during flood season to be used as labour to work the blocks and float them down the flood planes).

An example in the Imhotep's program of bringing African culture into math is using the Egyptian pyramids to teach trigonometry.
