Triangle)
Grade: 8
Sample Activities:
·
Students investigate the natural shapes that are
produced by growth. They look at how nature produces complex structures in
which basic shapes occur over and over. For example, spider webs, honeycombs,
pineapples, pinecones, nautilus shells, and snowflakes grow larger in a
systematic way (iteration).

Students learn about the natural shapes that are
produced by growth. They investigate how nature produces complex structures in
which basic shapes occur over and over. For example, spider webs, honeycombs,
and snowflakes grow larger in a systematic way (iteration). Students measure
the age of a tree by looking at its rings; this illustrates approximation.
Students produce geometric designs that illustrate these principles, as well as
fractals, where miniature versions of the entire design are evident within a
small portion of the design.
·
Students view the slides which accompany the activity
book, Fractals for the Classroom, Vol. 1, and determine why each picture might
have been included in a book about fractals.
