8 ) (+) Add and subtract vectors. [N-VM4]

a. (+) Add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes. [N-VM4a]

b. (+) Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum. [N-VM4b]

c. (+) Understand vector subtraction v - w as v + (-w), where -w is the additive inverse of w, with the same magnitude as w and pointing in the opposite direction. Represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise. [N-VM4c]

Title: Adding and Subtracting Vectors Lesson
Description:

This learning activity will be used during a lesson on Adding and Subtracting Vectors. Students will explore how to add vectors end-to-end, component-wise, and by the parallelogram rule, determine the direction of their sum, represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise. The teacher will use the Adding and Subtracting Vectors Lesson to cover the “I DO” and “We Do” portions of the lesson.

This activity was created as a result of the ALEX Resource Development Summit.

Title: Proof I Know How to Add and Subtract Vectors
Description:

This learning activity will be used to add and subtract vectors and is intended for an assessment activity. The students will complete the Adding and Subtracting Vectors Assessment to demonstrate mastery of how to add vectors end-to-end, component-wise, and by the parallelogram rule, determine the direction of their sum, represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise. 

This activity results from the ALEX Resource Development Summit.

Title: Precalculus and Advanced Topics Module 2, Topic D: Vectors in Plane and Space
URL: https://www.engageny.org/resource/precalculus-and-advanced-topics-module-2-topic-d-overview
Description:

Module 2, Topic D opens with a formal definition of a vector. The arithmetical work for vector addition, subtraction, scalar multiplication, and vector magnitude is explored along with the geometrical frameworks for these operations. Students solve problems involving velocity and other quantities that can be represented by vectors. Parametric equations are introduced allowing students to connect their prior work with functions to vectors.

Title: PhET: Vector Addition
URL: https://phet.colorado.edu/en/simulation/vector-addition
Description:

In this PhET activity, students will explore vectors in 1D or 2D, and discover how vectors add together. Students will specify vectors in Cartesian or polar coordinates, and see the magnitude, angle, and components of each vector. Students will experiment with vector equations and compare vector sums and differences. This activity could be used to help teach a lesson on probability. This PheET activity can be downloaded and assigned to Google Classroom.
