Explore the intrigue of why and how different civilizations built pyramids across millenniums of time and place. Connect functions with ancient and modern pyramidal buildings, considering their histories, geometries and building materials. Students will work in groups of approximately four to explore various pyramids and pyramidal buildings from ancient times to present day using videos and online resources around pyramids. Through the measurement, study of photographs, and data around varying pyramids, students will mathematically represent the silhouettes of pyramids using linear and piecewise functions, symmetries, and transformation.
