Transformations & Vectors

Scheme of work: GCSE Foundation: Year 10: Term 6: Transformations & Vectors

Prerequisite Knowledge

  • Use conventional terms and notations: points, lines, vertices, edges, planes, parallel lines, perpendicular lines, right angles, polygons, regular polygons and polygons with reflection and/or rotation symmetries;
  • identify an order of rotational and reflective symmetry for two-dimensional shapes
  • use the standard conventions for labelling and referring to the sides and angles of triangles; draw diagrams from the written description
  • Recognise linear functions in the form y = ± a and x = ± a

Success Criteria

  • Identify, describe and construct congruent and similar shapes, including on coordinate axes, by considering rotation, reflection, translation and enlargement (including fractional scale factors)
  • apply addition and subtraction of vectors, multiplication of vectors by a scalar, and diagrammatic and column representations of vectors

Key Concepts

  • An object is transformed to create an image.
  • Rotation, Translation and Reflections involve congruent objects and images whereas enlargement leads to the object is similar to the image.
  • Translation vectors are used to describe movements along Cartesian axes.
  • When reflecting objects the image is always the same distance from the line of reflection as the object.
  • Rotations and enlargements are constructed from a centre.
  • A scalar has direction only whereas a vector has direction and magnitude.
  • A vector has a magnitude and direction but its starting point is variable.
  • Parallel lines have vectors that are multiples of each other.
  • To add and subtract vectors is similar to collecting like terms.

Common Misconceptions

  • Translation vectors can incorrectly be written using the name notation as coordinate pairs.
  • Translations, Rotations, Enlargement and Reflections all come under the umbrella term of transformation. Students often confuse the term translation for transformation.
  • Students often have more difficulty describing single transformations rather than performing them.
  • Writing vectors in their simplest form by collecting like terms is often a problem in examinations.
