Vector Addition and Subtraction (2D)
Students will perform addition and subtraction of 2D vectors graphically (triangle/parallelogram rule) and algebraically.
Key Questions
- How do we add and subtract vectors graphically using the triangle and parallelogram rules?
- How do we add and subtract vectors using their column components?
- What is the resultant vector when two or more vectors are combined?

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.
