 Learning about Properties of Vectors and Vector Sums Using Dynamic SoftwareORC# 1471Resource InformationResource URL: http://www.nctm.org/standards/content.aspx?id=26888Resource Type: Content Supports -- TechnologiesDiscipline: MathematicsGrades: Grades 9–12Professional Commentary: With this NCTM E-Example, students manipulate a velocity vector to control the movement of a car to keep it from crashing into a wall. In the first of two activities, students understand that vectors are composed of both magnitude and direction, each of which can be manipulated in the game applet....MORE...
 Elementary Vector Analysis ORC# 3358Resource InformationResource Type: Content SupportsDiscipline: MathematicsGrades: Grades 11–PostsecondaryProfessional Commentary: This site is essentially a reference for the basic definitions and graphical interpretation of coordinate vectors, norm (or length) of a vector, vector addition, scalar multiplication, dot product, projection of a vector, and cross product of vectors. Some properties are illustrated and some examples are given....MORE...
 VectorsORC# 9828Resource InformationResource URL: http://mathforum.org/~klotz/Vectors/index.htmlResource Type: Content SupportsDiscipline: MathematicsGrades: Grades 11–12Professional Commentary: This site offers interactive explorations using Geometer's Sketchpad (a link to a free demo version is provided), as well as static pictures of vector models. Both are intended as supplementary material to help students in their first encounter with vectors....MORE...
 Straight Lines in 3-SpaceORC# 9787Resource InformationResource Type: Content SupportsDiscipline: MathematicsGrades: Grades 9–12Professional Commentary: This applet features five 3-D diagrams, each of a line in coordinate space. Each diagram can be rotated to show the line in reference to all planes in an x-y-z system....MORE...
 Spatial CoordinatesORC# 9786Resource InformationResource Type: Content SupportsDiscipline: MathematicsGrades: Grades 8–12Professional Commentary: This applet offers graphing in 3-dimensional space. A dynamic 3-D diagram shows the x, y, and z axes, which can be translated or rotated....MORE...
