Lesson Plan: Scalar Projection Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the scalar projection of a vector onto another vector.


Students will be able to

  • find the component of a vector 𝐴 in the direction of another vector 𝐵 when given
    • the components of vectors 𝐴 and 𝐵,
    • the magnitude of vector 𝐴 and the angle between vectors 𝐴 and 𝐵.


Students should already be familiar with

  • finding the magnitude of a vector,
  • the scalar (dot) product,
  • unit vectors,
  • vectors in 3D.


Students will not cover

  • vector projection,
  • vector (cross) product.
