#### Ellipse Elements and Equations

Challenge your class to provide an ellipse when given two points and two lines. The lesson presents both graphical and analytical methods to writing the equation of an ellipse. The class investigates its components, how they relate to...

Lesson Planet

#### Transformations with Circles and Ellipses

High schoolers use problem solving skills to rotate, reflect, translate, and dilate a given ellipse and circle. Students graph their circles and ellipses and practice writing and solving equations based on their graphs.

Lesson Planet

#### Ellipses: The Ellipse

Learners explore ellipses by changing the lengths and orientation of the major and minor axis. Using the interactive, they determine the equation of the ellipse and its eccentricity. Given an equation the scholars identify the center,...

#### Constructing an Ellipse

Investigate the equation of an ellipse. In this equation of an ellipse equation lesson plan, students construct an ellipse by dragging a point around two foci. They derive the equation of an ellipse by finding the distance between the...

Lesson Planet

#### The Line and the Ellipse

What do a line and an ellipse have in common? Maybe zero, one, or two points! Learners consider the equation of an ellipse and a line to determine if their graphs have any shared points. They then write a system of equations, including...

#### What is an Ellipse?

This video answers the question, �What is an ellipse?� It gives a definition of an ellipse, shows the ellipses relation of a plane to a cone, and the names of different parts of the ellipse.

Lesson Planet

#### Ellipse

High schoolers explore the concept of ellipses. In this ellipses lesson plan, they construct ellipses on their paper and follow directions on a worksheet that allow them to investigate an ellipse in more depth by looking at the major...

Lesson Planet

#### Ellipse

Students find the center, vertices, foci, and eccentricity of ellipses using the subscriptions website www.explorelearning.com. They graph elliptical functions and solve application problems involving ellipses.

Lesson Planet

#### Foci of an Ellipse

The foci of an ellipse are explored in this video. First, foci are shown as the two points on the major axis such that the sum of the distance from a point on the ellipse and the foci points is the same as the distance from any point on...

Lesson Planet

#### Conic Sections: Intro to Ellipses

In this video, the equation and graph of an ellipse is explored by first centering the ellipse at the origin, and then shifting it and showing how that change is reflected in the equation. The terms minor axes, major axes, semi-minor...

#### Introduction to Conics - The Ellipse

High schoolers identify and graph ellipses. After a teacher led discussion on shapes created when intersected by a plane and the use of conic sections, learners create a graphic organizer containing the information. A United Streaming...

Lesson Planet

#### The Ellipse

This is a practical sheet with the instructions to draw a set of ellipses. After following the diagrams, there are ten questions to complete, with calculations expected for alternate orbits and comparisons related to actual planets in...

Lesson Planet

#### Ellipses and Kepler's First Law

The class examines graphs in the form r = F(Â¿Â¿) in polar coordinates (r, Â¿Â¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...
