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: It's Just the Beginning...Adding And Subtracting Vectors
Description:

This learning activity will be used to introduce adding and subtracting vectors and is intended as an introduction or engagement activity. The students will watch the Adding and Subtracting Vectors video to learn how to add and subtract vectors. This activity will lead to learning 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 was created as a result of the ALEX Resource Development Summit.

Subject: Mathematics (9 - 12)
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
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.
