This is a Level 2 Geometry activity from the Figure It Out Series.
make a pattern by translating or rotating a shape
This activity gets students to apply translational and rotational symmetry to create freeze-type patterns. The method suggested uses a printing block.
The patterns created by translation need to preserve the orientation of the figure. For example:
By contrast, the patterns created by rotation involve a change in orientation. For example:
Students may find that they can apply translation and rotation in combination. For example:
Another way of making patterns by reflection is to cut a tracing block from a square of card. Note that it is wise to mark the original corners of the square before cutting to help keep track of the original shape. For example:
The pattern can be duplicated across the whole page by repeated reflection.

Making Patterns
In this unit students explore patterns involving transformations of shapes. . Students make and identify patterns that involve translation, reflection, and rotation. They make their own patterns to show the transformations. The unit concludes with students making a picture and discussing with others how they included the different transformation elements.
