Activity:

 

Students choose a basic shape (ideally one that is not regular with equal angles and equal sides) and create a design by sliding and/or turning the shape.

Example:

 

 

slide

 

flip

 

 

 

Teacher Notes:

Students should learn about the flip (a mirror image of the original shape) since it is the most basic transformation (change in position), and other transformations can be obtained by combining flips. Additionally, a shape resulting from a slide (orienting the shape the same way but sliding it to a different position) should also be explored at this level.3
