This activity investigates concepts such as the shortest distance between two points in a plane, and the shortest distance between a line and a point not on the line. The analytical explanation of these concepts is supported with visual...

Seventh graders find the distance between points on a number line by counting and by using subtraction. They then use subtraction to find differences in temperatures. Students discover that the distance between any two points on the...

Practice finding the distance between two points on the coordinate plane that share the same x- or y-coordinate. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

MathWorld offers a definition of vanishing point; contains diagrams of one, two, and three point perspective drawings with arrows pointing to the vanishing points.

Absolute Value is the distance from zero on the number line or the distance between two points. This site from the University of Saskatchewan has examples and learning exercises for a better understanding of absolute value. Site by...

Students make connections between the coordinate grid and Geometry by finding the distance of line segments using the coordinate plane. This lesson includes a detailed lesson plan, slides containing notes and problems, and a...

Find the midpoint of a segment on the coordinate plane, or find the endpoint of a segment given one point and the midpoint. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...
