Put together the pieces and model a parabola. Learners work through several examples to develop an understanding of a parabola graphically and algebraically. 

Explore the properties of parabolas in this lesson. Construct a parabola given a focus and a directrix on the Ti-Nspire. Write equations of parabolas in vertex form and determine the a value of a parabola given a focus and directrix.

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

A deceptively simple question setup leads to a number of attack methods and a surprisingly sophisticated solution set in this open-ended problem. Young geometers of different strengths can go about defining the solutions graphically,...

Learn to identify the properties of parabolas. Students define parabola as the locus of all points equidistant from a fixed point and a fixed line. Also, interpret the equation for a parabola in vertex form and gain a visual...

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

Students are introduced to the construction geometrically of parabolas. Using a software program, they identify lines, segments and midpoints. They label the parabolas properties and characteristics and use a formula to determine the...

Sixth graders discover the ways archaeologists examine artifacts and where they are found. After being introduced to new vocabulary, they use artifacts from their own lives and discover what could be told about their life from them. ...

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

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...

Students engage in a lesson that focuses on analytic geometry. The lesson asked them to apply skills of relating equations when plotting them on the coordinate plane. Students construct the equations using specific criteria and apply them.

Students slve a case of unclear heredity using three lines of evidence and knowledge gained from the lesson in this biology lesson about Mendelian inheritance. The lesson includes handouts and a question sheet for final, individual...
