Ancient Aztecs
Is it a calendar? A religious symbol? A political statement? One thing for certain is that Aztec sun stone designs remain an important symbol in Mexican cultural art. Young artists craft their own Aztec Sun design incorporating ideas...
Balanced Assessment
On Averages and Curves
Determine the average on a curve. The class finds graphical representations of averages and expresses them both symbolically and on the graph. The assessment requires class members to justify using average to describe graphs.
Curated OER
Symmetry in Butterflies
Students create a butterfly displaying a mirror image of itself to show that it is symmetrical. In this symmetry lesson plan, students go over symmetry in different shapes and identify patterns in butterflies.
