Multiple transformations

I can carry out multiple transformations on a shape.

Lesson details

Key learning points

  1. A shape can be transformed more than once.
  2. The first transformation is performed on the object.
  3. The second transformation is performed on the image.
  4. The third transformation is performed on the new image etc.

Common misconception

The number of spaces to translate a shape can be worked out by counting the squares on the grid.

If there are axes, then it is important to check the scales. The length of one square does not always represent one unit.

Keywords

  • Object - The object is the starting figure before a transformation has been applied.

  • Image - The image is the resulting figure after a transformation has been applied.

  • Vector - A vector can be used to describe a translation.

  • Polygon - A polygon is a flat (2D), closed figure made up of straight line segments.

Learning cycle 2 includes activities in Desmos (geometry). The links to the activities can be shared with pupils so that they can access them on their own or school device.
