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

Students investigate circles and compound locus. For this geometry lesson, 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 instructional activity, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students 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. Students solve...

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.
