Activities (for students)
Activities for Students: Exponential Growth through Pattern Exploration

Betty Brown 

February 2005, Volume 98, Issue 6, Page 434

Abstract:
An activity using iterations to form the Sierpinski Triangle and connecting algebra, geometry, and arithmetic. Activities are hands-on, open-ended activities that encourage problem solving, reasoning, communication, and mathematical connections. Activities is a regular feature of Mathematics Teacher and highlights activities that develop conceptual understanding of mathematics topics. Students use geometric constructions to create the Sierpinski triangle and to explore the concepts of similarity, self-similarity, area, and perimeter while reinforcing exponent and rational number operations.
