In an article published in the November 2016 issue of At Right Angles we had seen how geometrical fractal constructions lead to algebraic thinking. The article had highlighted the iterative construction processes, which lead to the Sierpinski triangle and the Sierpinski Square carpet. Further the idea of self-similarity within these fractals was reinforced through the recursive and explicit relationships between various stages of the fractal constructions.

This article describes how pre-service teachers explored fractal constructions using pictorial, numerical, symbolic and graphical representations. 

Here is Volume 16, No. 4 of Vigyan Prasar's monthly Science magazine Dream 2047 with articles on fractals - the fabric of nature and other topics.
