Common mistakes

What learners typically get wrong, and how to fix it.

  • Adds x of one vector to y of the other.

    Correction: Add x with x, y with y.

  • Forgets that a negative component means the opposite direction.

    Correction: Draw the vector to check.

Teacher tips

  • · Draw vectors on squared paper end to end.

Parent tips

  • · Give directions as '3 steps right, 2 steps up'.

Real-life applications

  • · Navigation, forces in physics, game movement.
