This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit, pupil understanding of vectors is deepened with pupils exploring column vector notation and arithmetic procedures.
Lesson Summary
You will learn to find the sum and difference with vectors written algebraically.
Key Notes
- Addition and subtraction with vectors follows the algebraic manipulation rules you know.
- Vectors that are like terms can be collected.
- The resultant vector can be drawn by sketching.
Vocabulary To Learn
- Resultant vector: A resultant vector is the single vector that produces the same effect as a combination of other vectors.
Common Mistakes To Avoid
- When calculating the resultant vector, pupils can incorrectly sum vectors due to opposite directions or proportions of vectors.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Addition and subtraction with vectors follows the algebraic manipulation rules you know. Vectors that are like terms can be collected.
2. Use this key word in a maths sentence and explain it clearly. 'Resultant vector'
A resultant vector is the single vector that produces the same effect as a combination of other vectors. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: When calculating the resultant vector, pupils can incorrectly sum vectors due to opposite directions or proportions of vectors. Correction: Encourage pupils to write a clear vector pathway; sometimes using highlighters can help visualize this pathway.
