Summary
This resource pack covers the Year 7 transformations curriculum: translation using vector notation, reflection in mirror lines (including coordinate axes), rotation about a given centre, and symmetry. The materials were developed for the Tiffin School Year 7 scheme of work and do not include enlargement. Three resource packs are available.
Core Ideas
- A translation slides every point the same distance in the same direction, described by a column vector
- A reflection flips a shape over a mirror line with each point equidistant from the line
- A rotation turns a shape about a fixed centre and must be described with centre, angle, and direction
- Line symmetry: a shape can be folded along a line so both halves match
- Rotational symmetry: a shape looks the same after rotation through less than 360°
Teaching and Assessment Focus
- For each transformation type, students should both perform and describe transformations
- Use coordinate grids extensively for practical work
- Emphasise the formal language: “translation by vector (x, y)”, “reflection in the line y = …”, “rotation of 90° clockwise about (0, 0)”
- The Sherlocked Transformations puzzle activity provides engaging consolidation
- QQQ (Quick Quiz Questions) assess key knowledge efficiently
