Subject: Mathematics Title: Learning about Properties of Vectors and Vector Sums Using Dynamic Software: Sums of Vectors and Their Properties
Add Bookmark
Description: This is part two of a twopart eexample from Illuminations that illustrates how using a dynamic geometrical representation can help students develop an understanding of vectors and their properties. In this part, Sums of Vectors and Their Properties, students extend their knowledge of number systems to the system of vectors. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards for School Mathematics (PSSM). Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath Investigations.

Description: In this twolesson unit, from Illuminations, students manipulate a velocity vector to control the movement of an object in a gamelike setting. They develop an understanding that vectors are composed of both magnitude and direction, and extend their knowledge of number systems to the system of vectors.
