Find curves in monuments, buildings and water jets and fit a parabola to them using dynamic geometry software." Quadratic graphs are everywhere you look. They can describe the paths of rockets, balls and jets of water. Because of their symmetry you will see parabolas in bridges, buildings, sand dunes... Understanding their equations is hence hugely important in the fields of engineering and science. This...

I use this performance task assessment at the conclusion of our unit on triangle properties. Ultimately the unit is about making strategic use of mathematical tools, an idea that is explored through the following content items:* Perpendicular bisectors and angle bisectors.* Triangle medians and midsegments.* Triangle centers: circumcenter, incenter, orthocenter, centroid.* Geometric constructions: compass & straightedge, paper folding, geometry software, and coordinate geometry.This…
