Lesson Plan: Adding and Subtracting Vectors in 2D Mathematics • 12th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to add and subtract vectors in 2D.

Objectives

Students will be able to

  • add vectors in 2D, when given algebraically,
  • subtract vectors in 2D, when given algebraically,

  • find the components of an unknown vector given the result of the addition or subtraction with a known vector.

Prerequisites

Students should already be familiar with

  • magnitude of a 2D vector,
  • component form and unit vector form of a vector.

Exclusions

Students will not cover

  • scalar multiplication,
  • vectors in 3D,
  • adding and subtracting matrices.
