Students learn how to solve problems with vectors when ratio notation is used to define a magnitude.

As learning progresses they begin to consider how vectors can show whether two shapes are similar or congruent.

**Differentiated Learning Objectives**

- All students should be able to solve vector problems using addition and subtraction of like terms.
- Most students should be able to use ratio notation to solve problems involving vectors.
- Some students should be able to define geometrical properties between two shapes using vectors.
