Lessons using the Image_and_Cursor applet
How Far Between Cities?
Part I is a step-by-step activity encouraging students to "see" how an applet can be used to form a right triangle on a map. Part II shows students how to apply the Pythagorean Theorem to calculate the distance between two points on a map.
Teacher Lesson Plan: Part I and Part II || Student Page: Part I and Part II || Applet Page

Suggestions for Finding Maps
Four possible sources of maps are explained so that teachers can find local maps.
Directions

How to Change Maps/Photos
A "how-to" for changing the current map or portrait photo to one of your choosing.
Directions

How Much Wider is a Smile?
Students use the coordinate system to determine the percentage increase of a smiling mouth from a resting mouth.

Lessons using the Parameter_Plane applet
Exploring Roots of a Quadratic Equation
Students view the graph of the quadratic equation, x^2 + x - 6 and they are able to manipulate a second graph of x^2 - bx + a on the same plane. Explorations include identifying the roots, the connection between the graph and factoring, etc.
