Recently we did a unit for homeschool on the conquistadors, Aztecs, Incas, Myans and pirates. We read this great book about the Lost City, learned about Pizarro and Cortez, made some Spanish doubloons and finished off with some gold Inca masks.
We used gold foil to create our Inca masks and our Spanish doubloons. We learned about symmetry while drawing our masks, and then texture as we pushed the foil in and out to create the textures of the facial features and designs.
We added a bit of color with some colored permanent markers and additional decorations such as feathers and beads.
And yes... that mess you see on the table is what you see at our house on a regular basis during school time.
