Introduction to Vectors (2D)
Students will define vectors as quantities with magnitude and direction, and represent them graphically and as column vectors in 2D.
About This Topic
Students will define vectors as quantities with magnitude and direction, and represent them graphically and as column vectors in 2D.
Key Questions
- How does extending vectors from two to three dimensions affect operations such as addition, scalar multiplication, and magnitude calculation, and what new geometric considerations arise?
- Explain how a position vector in three-dimensional space uniquely locates a point relative to the origin, and how this representation connects to the Cartesian coordinate system.
- Analyse how unit vectors and direction cosines characterise the orientation of a three-dimensional vector, and apply this to decompose a vector along specified directions.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
