Students define the five rules of loci. In this geometry instructional activity, students identify the locus of points that creates a circle. They calculate the distance from a fixed line and point.

Learners investigate circles and compound locus. In this geometry lesson plan, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students differentiate between ellipse and hyperbola. In this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Young scholars review the definition of a parabola. They trace a parabola by locating points the same distance from a point as they are to a line. Students develop an equation for a parabola with its vertex at the origin. Young scholars...

NOT A LESSON Students

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.
